Class A * Class B * Class C * Class R
Prospectus dated September 30, 2002

This Supplement updates the performance, expense and financial information contained in the Prospectus dated September 30, 2002 for Class A, Class B, Class C and Class R shares of the Delaware Strategic Income Fund (the "Prospectus"). This Supplement should be read in conjunction with the Prospectus. The Prospectus may be obtained by writing or calling your investment dealer or by contacting the Fund's national distributor, Delaware Distributors, L.P., at 2005 Market Street, Philadelphia, PA 19103-7094 or by calling 800 523-1918.

How has the Fund performed?

This bar chart and table can help you evaluate the risks of investing in the Fund. We show how returns for the Fund's Class A shares have varied over the past six calendar years, as well as the average annual returns of all shares for the one-year, five-year and lifetime periods. Returns are not shown for Class R shares because the class has not commenced operations. The Fund's past performance does not necessarily indicate how it will perform in the future. The returns reflect an expense limitation. The returns would be lower without the limitation.

Year-by-year total return (Class A)

[GRAPHIC OMITTED: BAR CHART SHOWING YEAR BY YEAR TOTAL RETURN (CLASS A)]

1997	1998	1999	2000	2001	2002
9.41%	2.24%	-2.47%	-3.01%	0.30%	13.35%

As of June 30, 2003, the Fund's Class A shares had a calendar year-to-date return of 12.83%. During the periods illustrated in this bar chart, Class A's highest quarterly return was 7.72% for the quarter ended June 30, 2003 and its lowest quarterly return was -2.23% for the quarter ended September 30, 2000.

The maximum Class A sales charge of 4.50%, which is normally deducted when you purchase shares, is not reflected in the total returns in the previous paragraph or in the bar chart. If this fee were included, the returns would be less than those shown. The average annual returns shown in the table below do include the sales charge.

Average annual returns for periods ending 12/31/02

	1 year	5 years	Lifetime**
Class A return before taxes	8.21%	0.99%	2.82%
Class A return after taxes on distributions	7.00%	-1.96%	-0.31%
Class A return after taxes on distributions and sale of Fund shares	4.98%	-0.71%	0.66%
Class B return before taxes*	8.22%	4.59%	2.80%
Class C return before taxes*	11.22%	5.66%	2.79%
Lehman Brothers Aggregate Bond Index (reflects no deduction for fees, expenses or taxes)	10.25%	7.55%	8.08%

The Fund's returns are compared to the performance of the Lehman Brothers Aggregate Bond Index. You should remember that unlike the Fund, the index is unmanaged and does not reflect the costs of operating a mutual fund, such as the costs of buying, selling and holding securities. Maximum sales charges are included in the Fund returns above.

After-tax performance is presented only for Class A shares of the Fund. The after-tax returns for other Fund classes may vary. Actual after-tax returns depend on the investor's individual tax situation and may differ from the returns shown. After-tax returns are not relevant for shares held in tax-deferred investment vehicles such as employer-sponsored 401(k) plans and individual retirement accounts. The after-tax returns shown are calculated using the highest individual federal marginal income tax rates in effect during the periods presented and do not reflect the impact of state and local taxes. Past performance, both before and after taxes, is not a guarantee of future results.

* Total returns assume redemption of shares at end of period. If shares were not redeemed, the returns before taxes for Class B would be 12.22%, 5.67% and 2.80% for the one-year, five year and lifetime periods, respectively. If shares were not redeemed, the returns before taxes for Class C would be 12.22%, 5.66% and 2.79% for the one-year, five-year and lifetime periods, respectively. Returns are not shown for Class R shares because the class has not commenced operations.

** Lifetime returns are shown if the Fund or Class existed for less than 10 years. Inception date for Class A, Class B and Class C shares was October 1, 1996. Lehman Brothers Aggregate Bond Index returns are for 10 years. Index return for Class B and Class C lifetimes was 8.08%. Returns are not shown for Class R shares because the class has not commenced operations.

What are the Fund's fees and expenses?

Sales charges are fees paid directly from your investments when you buy or sell shares of the Fund. You do not pay sales charges directly from your investments when you buy or sell Class R Shares.	CLASS	A	B	C	R
	Maximum sales charge (load) imposed on purchases as a percentage of offering price	4.50%	none	none	none
	Maximum contingent deferred sales charge (load) as a percentage of original purchase price or redemption price, whichever is lower	none1	4.00%2	1.00%3	none
	Maximum sales charge (load) imposed on reinvested dividends	none	none	none	none
	Redemption fees	none	none	none	none
	Exchange fees	none	none	none	none

Annual fund operating expenses are deducted from the Fund's assets.	Management fees	0.65%	0.65%	0.65%	0.65%
	Distribution and service (12b-1) fees	0.30%4	1.00%	1.00%	0.60%
	Other expenses	0.90%	0.90%	0.90%	0.90%
	Total annual fund operating expenses5	1.85%	2.55%	2.55%	2.15%
	Fee waivers and payments	(0.05%)	(0.00%)	(0.00%)	(0.00%)
	Net expenses	1.80%	2.55%	2.55%	2.15%

This example is intended to help you compare the cost of investing in the Fund to the cost of investing in other mutual funds with similar investment objectives. We show the cumulative amount of Fund expenses on a hypothetical investment of $10,000 with an annual 5% return over the time shown. 6 This is an example only, and does not represent future expenses, which may be greater or less than those shown here.	CLASS 7	A	B	B	C	C	R
				(if redeemed)		(if redeemed)
	1 year	$629	$258	$658	$258	$358	$218
	3 years	$1,006	$793	$1,019	$793	$793	$673
	5 years	$1,406	$1,355	$1,505	$1,355	$1,355	$1,154
	10 years	$2,522	$2,714	$2,714	$2,885	$2,885	$2,483

1 A purchase of Class A shares of $1 million or more may be made at net asset value. However, if you buy the shares through a financial advisor who is paid a commission, a contingent deferred sales charge will apply to certain redemptions made within two years of purchase. Additional Class A purchase options that involve a contingent deferred sales charge may be permitted from time to time and will be disclosed in the Prospectus if they are available.

2 If you redeem Class B shares during the first year after you buy them, you will pay a contingent deferred sales charge of 4.00%, which declines to 3.00% during the second year, 2.25% during the third year, 1.50% during the fourth and fifth years, 1.00% during the sixth year, and 0.00% thereafter.

3 Class C shares redeemed within one year of purchase are subject to a 1% contingent deferred sales charge.

4 Class A shares are subject to a 12b-1 fee of 0.30% of average daily net assets and Class B and Class C shares are each subject to a 12b-1 fee of 1.00% of average daily net assets. Class R shares are subject to a 12b-1 fee of 0.60% of average daily net assets. The Fund's distributor has contracted to limit the Class A shares' 12b-1 fee through March 31, 2004 to no more than 0.25% of average daily net assets.

5 The investment manager has agreed to waive fees and pay expenses through March 31, 2004 in order to prevent total operating expenses (excluding taxes, interest, brokerage fees, extraordinary expenses and 12b-1 fees) from exceeding 0.75% of average daily net assets. The fees and expenses shown in the table above do not reflect the voluntary expense caps by the manager. The following table shows operating expenses which are based on the most recently completed fiscal year and reflects the manager's current fee waivers and payments.

Fund operating expenses including voluntary expense caps in place through March 31, 2004.	CLASS	A	B	C	R
	Management fees	0.00%	0.00%	0.00%	0.00%
	Distribution and service (12b-1) fees	0.25%	1.00%	1.00%	0.60%
	Other expenses	0.75%	0.75%	0.75%	0.75%
	Total annual fund operating expenses	1.00%	1.75%	1.75%	1.35%

6 The Fund's actual rate of return may be greater or less than the hypothetical 5% return we use here. This example assumes that the Fund's total operating expenses remain unchanged in each of the periods we show. In addition, this example does not reflect the voluntary expense cap described in footnote 5.

7 The Class B example reflects the conversion of Class B shares to Class A shares after approximately eight years. Information for the ninth and tenth years reflects expenses of the Class A shares.

Financial highlights

The financial highlights tables are intended to help you understand the Fund's financial performance. All "per share" information reflects financial results for a single Fund share. This information has been audited by Ernst & Young LLP, whose report, along with the Fund's financial statements, is included in the Fund's annual report, which is available upon request by calling 800 523-1918. Financial highlights are not shown for Class R because the class has not commenced operations.

1 As required, effective August 1, 2001, the Fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies that require amortization of all premium and discounts on debt securities and the recording of paydown gains and losses on mortgage- and asset-backed securities as an adjustment to interest income. The effect of these changes for the year ended July 31, 2002 was a decrease in net investment income per share of $0.031, an increase in net realized and unrealized gain (loss) per share of $0.031, and a decrease in the ratio of net investment income to average net assets of 0.80%. Per share data and ratios for periods prior to August 1, 2001 have not been restated to reflect these changes in accounting.

2 The average shares outstanding method has been applied for per share information.

3 Total investment return is based on the change in net asset value of a share during the period and assumes reinvestment of dividends and distributions at net asset value and does not reflect the impact of a sales charge. Total investment return reflects a waiver and payment of fees by the manager and distributor, as applicable. Performance would have been lower had the expense limitation not been in effect.
