Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Example, affect the Fund's performance.During the most recent fiscal year, the Fund's portfolio turnover rate was 177% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example shows costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-, five-, and ten-year periods. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:11.16pt;font-weight:bold;text-transform:uppercase;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal circumstances, the Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in bonds of issuers in a number of different countries, which may include the United States. For purposes of this 80% policy, bonds include, without limitation, bonds, debt instruments, and other fixed income and income-producing debt instruments, of any kind, issued or guaranteed by governmental or private-sector entities. The Fund may invest in securities of issuers located in developed and emerging market countries. Countries with emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, the United Kingdom, the United States, and most of the countries of western Europe. Securities may be denominated in foreign currencies or in U.S. dollars. The Fund may hedge its exposure to securities denominated in foreign currencies. The Fund may also borrow money from banks and invest the proceeds of such loans in portfolio securities to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder (the “1940 Act”). This investment technique is known as “leveraging.” The Fund invests primarily in securities, which, at the time of investment, are rated investment grade. Investment grade refers to a rating given by one or more nationally recognized statistical rating organizations (“NRSROs”) ( e.g ., rated Baa3 or above by Moody’s Ratings (“Moody’s”), or BBB- or above by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”)) or, if unrated, determined by the Fund to be of comparable quality. The Fund may also invest in preferred stocks, money market instruments, municipal bonds, commercial and residential mortgage-related securities, asset-backed securities, other securitized and structured debt instruments, private placements, and sovereign debt. The Fund may also invest its assets in bank loans and in floating rate secured loans (“Senior Loans”). Although the Fund may invest a portion of its assets in debt instruments rated below investment grade (sometimes referred to as “high-yield securities”, “high-yield bonds”, or “junk bonds”), the Fund will seek to maintain a minimum weighted average portfolio quality rating of at least investment grade. Below investment grade refers to a rating given by one or more NRSROs (e.g., rated Ba1 or below by Moody’s, or BB+ or below by S&P or Fitch) or, if unrated, determined by the Fund to be of comparable quality. The dollar-weighted average duration of the Fund will generally range between two and nine years. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the debt instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the debt instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%. The Fund may use derivatives, including futures, swaps (including interest rate swaps, total return swaps, and credit default swaps), and options, among others, to seek to enhance return, to hedge some of the risks of its investments in debt instruments, or as a substitute for a position in an underlying asset. The Fund may, without limitation, seek to obtain market exposure to the instruments in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls and reverse repurchase agreements). The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), to the extent permitted under the 1940 Act. The investment process focuses on allocating assets among various sectors of the global bond markets and buying bonds at a discount to their intrinsic value. The sub-adviser (the “Sub-Adviser”) utilizes proprietary quantitative techniques to identify bonds or sectors that it considers to be cheap relative to other bonds or sectors based on their historical price relationships. Teams of asset specialists use this relative value analysis to guide them in the security selection process. In evaluating investments for the Fund, the Sub-Adviser takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment. Among the factors considered, the Sub-Adviser expects typically to take into account environmental, social, and governance (“ESG”) factors to determine whether one or more factors may have a material effect. In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer’s ESG standing. ESG factors will be only one of many considerations in the Sub-Adviser’s evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in an issuer, if at all, will depend on the analysis and judgment of the Sub-Adviser. The Sub-Adviser may sell assets for a variety of reasons, such as to secure gains, in response to a change in the Sub-Adviser's original investment considerations, to limit losses, to adjust the characteristics of the Fund's overall portfolio, or redeploy assets into opportunities believed to be more promising. The Fund may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.

Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Bank Instruments Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Bank Instruments: Bank instruments include certificates of deposit, fixed time deposits, bankers’ acceptances, and other debt and deposit-type obligations issued by banks. Changes in economic, regulatory, or political conditions, or other events that affect the banking industry may have an adverse effect on bank instruments or banking institutions that serve as counterparties in transactions with the Fund. In the event of a bank insolvency or failure, the Fund may be considered a general creditor of the bank, and it might lose some or all of the funds deposited with the bank. Even where it is recognized that a bank might be in danger of insolvency or failure, the Fund might not be able to withdraw or transfer its money from the bank in time to avoid any adverse effects of the insolvency or failure. Volatility in the banking system may impact the viability of banking and financial services institutions. In the event of failure of any of the financial institutions where the Fund maintains its cash and cash equivalents, there can be no assurance that the Fund would be able to access uninsured funds in a timely manner or at all and the Fund may incur losses. Any such event could adversely affect the business, liquidity, financial position and performance of the Fund.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Borrowing Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Borrowing: Borrowing creates leverage, which may increase expenses and increase the impact of the Fund’s other risks. Borrowing may exaggerate any increase or decrease in the Fund’s net asset value causing the Fund to be more volatile than a fund that does not borrow. Borrowing for investment purposes is considered to be speculative and may result in losses to the Fund.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | China Investing Risks [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	China Investing Risks: The Chinese economy is generally considered an emerging and volatile market. Although China has experienced a relatively stable political environment in recent years, there is no guarantee that such stability will be maintained in the future. Significant portions of the Chinese securities markets may become rapidly illiquid because Chinese issuers have the ability to suspend the trading of their equity securities under certain circumstances, and have shown a willingness to exercise that option in response to market volatility, epidemics, pandemics, adverse economic, market or political events, and other events. Political, regulatory and diplomatic events, such as the U.S.-China “trade war” that intensified in 2018, could have an adverse effect on the Chinese or Hong Kong economies and on related investments. In addition, U.S. or foreign government restrictions on investments in Chinese companies or other intervention could negatively affect the implementation of the Fund’s investment strategies, such as by precluding the Fund from making certain investments or causing the Fund to sell investments at disadvantageous times. •Investing through Bond Connect: Chinese debt instruments trade on the China Interbank Bond Market (the “CIBM”) and may be purchased through a market access program, known as “Bond Connect,” that is designed to, among other things, enable foreign (non-U.S.) investment in the People’s Republic of China. There are significant risks inherent in investing in Chinese debt instruments, similar to the risks of investing in debt instruments in other emerging markets. The prices of debt instruments traded on the CIBM may fluctuate significantly due to low trading volume and potential lack of liquidity. The rules to access debt instruments that trade on the CIBM through Bond Connect are relatively new and subject to change, which may adversely affect the Fund's ability to invest in these instruments and to enforce its rights as a beneficial owner of these instruments. Trading through Bond Connect is subject to a number of restrictions that may affect the Fund’s investments and returns.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Company: The price of a company’s stock could decline or underperform for many reasons, including, among others, poor management, financial problems, reduced demand for the company’s goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Credit Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Credit: The Fund could lose money if the issuer or guarantor of a debt instrument in which the Fund invests, or the counterparty to a derivative contract the Fund entered into, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services, or otherwise) as unable or unwilling, to meet its financial obligations. Asset-backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Credit Default Swaps Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Credit Default Swaps: The Fund may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a credit default swap is generally obligated to pay the seller an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default, on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount if the swap is cash settled. As a seller of a credit default swap, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity, and leveraging risks, and the risk that the swap may not correlate with its reference obligation as expected. Certain standardized credit default swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that it will achieve that result, and in the meantime, central clearing and related requirements expose the Fund to different kinds of costs and risks. In addition, credit default swaps expose the Fund to the risk of improper valuation.

Risk [Text Block]	rr_RiskTextBlock	Currency: To the extent that the Fund invests directly or indirectly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those foreign (non-U.S.) currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged by the Fund through foreign currency exchange transactions.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Derivative Instruments Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying asset, reference rate, or index credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the asset, reference rate, or index being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Environmental Social and Governance Fixed Income [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Environmental, Social, and Governance (Fixed Income): The Sub-Adviser’s consideration of ESG factors in selecting investments for the Fund is based on information that is not standardized, some of which can be qualitative and subjective by nature. The Sub-Adviser’s assessment of ESG factors in respect of obligations of an issuer may rely on third-party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of the Fund’s assets that will be invested in obligations of issuers that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may choose not to invest in obligations of issuers that compare favorably to obligations of other issuers on the basis of ESG factors. It is possible that the Fund will have less exposure to obligations of certain issuers due to the Sub-Adviser’s assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Floating Rate Loans Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan (which can include certain bank loans), the Fund will experience a reduction in its income and a decline in the market value of such floating rate loan. If a floating rate loan is held by the Fund through another financial institution, or the Fund relies upon another financial institution to administer the loan, the receipt of scheduled interest or principal payments may be subject to the credit risk of such financial institution. Investors in floating rate loans may not be afforded the protections of the anti-fraud provisions of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, because loans may not be considered “securities” under such laws. Additionally, the value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the borrower’s obligations under the loan, and such collateral may be difficult to liquidate. No active trading market may exist for many floating rate loans and many floating rate loans are subject to restrictions on resale. Transactions in loans typically settle on a delayed basis and may take longer than 7 days to settle. As a result, the Fund may not receive the proceeds from a sale of a floating rate loan for a significant period of time. Delay in the receipts of settlement proceeds may impair the ability of the Fund to meet its redemption obligations, and may limit the ability of the Fund to repay debt, pay dividends, or to take advantage of new investment opportunities.

Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign (Non-U.S.) Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions (or the threat of new or modified sanctions) or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region.

Class A C I P R R6 T and W Shares | Voya Global Bond Fund | High Yield Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	High-Yield Securities: Lower-quality securities including securities that are or have fallen below investment grade have greater credit risk and liquidity risk than higher-quality (investment grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower-quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity risk and price volatility.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Interest in Loans Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Interest in Loans: The value and the income streams of interests in loans (including participation interests in lease financings and assignments in secured variable or floating rate loans) will decline if borrowers delay payments or fail to pay altogether. A significant rise in market interest rates could increase this risk. Although loans may be fully collateralized when purchased, such collateral may become illiquid or decline in value.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Interest Rate Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other debt instruments; conversely, values generally rise as market interest rates fall. Interest rate risk is generally greater for debt instruments than floating-rate instruments. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is to changes in market interest rates. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. The U.S. Federal Reserve Board recently lowered interest rates following a period of consistent rate increases. Declining market interest rates increase the likelihood that debt instruments will be pre- paid . Rising market interest rates have unpredictable effects on the markets and may expose debt and related markets to heightened volatility. To the extent that the Fund invests in debt instruments, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in debt markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in debt markets. Fiscal, economic, monetary, or other governmental policies or measures have in the past, and may in the future, cause or exacerbate risks associated with interest rates, including changes in interest rates. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose debt and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose debt and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Fund’s operations and return potential.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Investment Model Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Investment Model: The Sub-Adviser’s proprietary investment model may not adequately take into account existing or unforeseen market factors or the interaction among such factors, including changes in how such factors interact, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for the Fund. Funds that are actively managed, in whole or in part, according to a quantitative investment model (including models that utilize forms of artificial intelligence, such as machine learning) can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Liquidity Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity: If a security is illiquid, the Fund might be unable to sell the security at a time when the Fund’s manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Fund to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Fund, which could cause the Fund to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress. Certain securities that are liquid when purchased may later become illiquid, particularly in times of overall economic distress or due to geopolitical events such as sanctions, trading halts, or wars. In addition, markets or securities may become illiquid quickly.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt instruments. Additionally, legislative, regulatory or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs, and impair the ability of the Fund to achieve its investment objectives.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Market Capitalization Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Capitalization: Stocks fall into three broad market capitalization categories: large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Market Disruption and Geopolitical Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Disruption and Geopolitical: The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, tariffs and other restrictions on trade or economic sanctions, rapid technological developments (such as artificial intelligence technologies), and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and global economies and markets, generally. For example, the COVID-19 pandemic resulted in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of the Fund’s investments, including beyond the Fund’s direct exposure to Russian issuers or nearby geographic regions. Furthermore, the prolonged conflict between Hamas and Israel, and the potential expansion of the conflict in the surrounding areas and the involvement of other nations in such conflict, such as the Houthi movement's attacks on marine vessels in the Red Sea, could further destabilize the Middle East region and introduce new uncertainties in global markets, including the oil and natural gas markets. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund’s investments. Any of these occurrences could disrupt the operations of the Fund and of the Fund’s service providers.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Mortgage and or Asset Backed Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Mortgage- and/or Asset-Backed Securities: Defaults on, or low credit quality or liquidity of, the underlying assets of the asset-backed (including mortgage-backed) securities may impair the value of these securities and result in losses. There may be limitations on the enforceability of any security interest or collateral granted with respect to those underlying assets, and the value of collateral may not satisfy the obligation upon default. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of debt instruments.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Municipal Obligations Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Municipal Obligations: The municipal securities market is volatile and can be affected significantly by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities. Among other risks, investments in municipal securities are subject to the risk that an issuer may delay payment, restructure its debt, or refuse to pay interest or repay principal on its debt.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Other Investment Companies Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Other Investment Companies: The main risk of investing in other investment companies, including ETFs, is the risk that the value of an investment company’s underlying investments might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the Fund’s expenses. The investment policies of the other investment companies may not be the same as those of the Fund; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Fund is typically subject. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF’s shares, which could cause a material decline in the ETF’s net asset value.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Portfolio Turnover [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Portfolio Turnover: A high portfolio turnover rate may increase transaction costs, which may lower the Fund’s performance and may increase the likelihood of capital gains distributions.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Preferred Stocks [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Preferred Stocks: Preferred stock generally has preference over common stock but is generally subordinate to debt instruments with respect to dividends and liquidation. Preferred stocks are subject to the risks associated with other types of equity securities, as well as greater credit or other risks than senior debt instruments. In addition, preferred stocks are subject to other risks, such as risks related to deferred and omitted distributions, limited voting rights, liquidity, interest rate, regulatory changes and special redemption rights.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Prepayment and Extension Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This risk is heightened in a falling market interest rate environment. Prepayment may expose the Fund to a lower rate of return upon reinvestment of principal. Also, if a debt instrument subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Extension risk is the risk that the issuer of a debt instrument will pay back the principal later than expected. This risk is heightened in a rising market interest rate environment. This may negatively affect performance, as the value of the debt instrument decreases when principal payments are made later than expected. Additionally, the Fund may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Restricted Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Restricted Securities: Securities that are legally restricted as to resale (such as those issued in private placements), including securities governed by Rule 144A and Regulation S, and securities that are offered in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended, are referred to as “restricted securities.” Restricted securities may be sold in private placement transactions between issuers and their purchasers and may be neither listed on an exchange nor traded in other established markets. Due to the absence of a public trading market, restricted securities may be more volatile, less liquid, and more difficult to value than publicly-traded securities. The price realized from the sale of these securities could be less than the amount originally paid or less than their fair value if they are resold in privately negotiated transactions. In addition, these securities may not be subject to disclosure and other investment protection requirements that are afforded to publicly-traded securities. Certain restricted securities represent investments in smaller, less seasoned issuers, which may involve greater risk.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Securities Lending Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Securities Lending: Securities lending involves two primary risks: “ investment risk ” and “ borrower default risk. ” When lending securities, the Fund will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Fund will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks.
Class A C I P R R6 T and W Shares | Voya Global Bond Fund | Sovereign Debt Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Sovereign Debt: Sovereign debt is issued or guaranteed by foreign (non-U.S.) government entities. Investments in sovereign debt are subject to the risk that a government entity may delay payment, restructure its debt, or refuse to pay interest or repay principal on its sovereign debt due to cash flow problems, insufficient foreign currency reserves, political considerations, social changes, the relative size of its debt position to its economy, or its failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a government entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting amounts owed on sovereign debt, such as bankruptcy proceedings, that a government does not pay.
