1.         BUSINESS

           Voice Control Systems, Inc. (the "Company" or "VCS") engages in the
design of voice recognition systems that allow for the voice control of
electronic machines and/or devices. Operating results for the nine months ending
September 30, 1998 are not necessarily indicative of the expected results for
the year. The unaudited financial statements include all adjustments, consisting
primarily of normal recurring accruals, which management considers necessary for
a fair presentation of such information.


2.         PER SHARE INFORMATION

           Net income (loss) per share is computed based upon the weighted
average number of outstanding shares of common stock. The Financial Accounting
Standards Board recently adopted, SFAS No. 128, Earnings Per Share (SFAS 128).
SFAS 128 requires a calculation of book "Basic" and "Diluted" earnings per
share. Basic earnings per share includes no dilution for common stock
equivalents.

3.         ACCOUNTS PAYABLE AND ACCRUED EXPENSES

           Accounts payable and accrued expenses consist of the following at
September 30, 1998:

<TABLE>
                  <S>                               <C>

</TABLE>

4.         INCOME TAXES

           The net operating loss (NOL) carryforwards of the Company expire from
1998 to 2012 and total approximately $36,620,000 as of September 30, 1998. The
Company has provided an allowance against its entire deferred tax asset relating
primarily to NOL carryforwards of approximately $12,450,000 since management
cannot determine that it is more likely than not that the deferred tax asset
will be realized. Approximately $1,225,000 in NOL carryforwards expired for the
year ended December 31, 1997. In connection with its merger and acquisition
activity the company and its predecessors have experienced an ownership change
as defined by Internal Revenue Code 382 the effect of such changes limits the
use of the Company's NOL in future years to approximately $1,405,000 annually.
Any portion of an NOL limited by IRC 382 not used in a given year can be carried
forward to subsequent years.

================================================================================

           The Company has provided an allowance for its entire deferred tax
asset as its realization is dependent upon future generation of taxable income
since management can not determine that it is more likely than not that the
deferred tax asset will be realized. Until such realization can be reasonably
determined based on established sources of earnings sufficient to utilize the
NOL carryforward, management will continue to provide an allowance for the
entire deferred tax asset.

           The following reconciles income tax expense at the federal statutory
rate to the actual tax expense for the nine months ended September 30:

           The Company's largest customer was also the holder of its short-term
convertible debt. The promissory note and accrued interest was converted to
1,300,694 shares of common stock on January 1, 1997. Accounts receivable from
the three largest customers were 21%, 13% and 13% of the total receivable

6.         NEW ACCOUNTING PRONOUNCEMENT

           In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income". This statement establishes standards for reporting and
display of comprehensive income, its components and accumulated balances.
Comprehensive income is defined to include all changes in equity except those
resulting from investments by owners and distributions to owners. Among other
disclosures, SFAS 130 requires that all Items that are required to be recognized
under current accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements.

           SFAS 130 is effective for financial statements for periods beginning
after December 15, 1997 and requires comparative information for earlier years
to be restated. The adoption of SFAS 130 had no effect on the financial
statements of the Company.

           In June 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards ("SFAS") No. 131, "Disclosures about
Segments of an Enterprise and Related Information" which is effective for the
Company for the year ending December 31, 1998. This statement establishes
standards for the way public business enterprises report information about
operating segments in annual financial statements and requires these enterprises
report selected information about operating segments in interim financial
reports issued to shareholders. The Company is currently evaluating the impact
that the adoption of SFAS 131 will have on its consolidated financial
statements.

7.         BUSINESS ACQUISITION

           On April 14, 1998 Voice Control Systems, Inc acquired 100% of the
common and preferred stock of Purespeech, Inc. in exchange for 2,016,920 shares
of Common Stock and cash of $2,140,000. This includes the conversion of
PureSpeech warrants to 317,608 of VCS warrants. The transaction was accounted
for using the purchase method of accounting. The preliminary allocation of the
purchase price is as follows:

           The acquired research and development was charged to expense as
research and development costs. Goodwill is being amortized over its estimated
useful life of five years.

PART I - FINANCIAL INFORMATION

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND 
         FINANCIAL CONDITION

RESULTS OF OPERATIONS

Nine months Ended September 30, 1998 vs. September 30, 1997

Sales increased 12% from $10,286,000 during the nine months ending September 30,
1997 to $11,529,000 during the nine months ending September 30, 1998. Three
customers, Dialogic Corporation, OKI Telecom and Intervoice accounted for 21%,
20%, and 10% respectively, of total sales for the nine months ending September
30, 1998. Dialogic Corporation, Glenayre and OKI Telecom accounted for 29%, 15%,
and 10% respectively, of total sales for the nine months ending September 30,
1997. Royalty, development and license fees, which increased 61% over the nine
months ending September 30, 1997, were 45% of total revenues for the nine months
ending September 30, 1998. Hardware sales, which decreased 9% over the nine
months ending September 30, 1997, were 51% of revenues in the nine months ending
September 30, 1998. The decrease in hardware sales is offset by the increase in
royalties, development and license fees as the company continues to transition
from primarily providing hardware to primarily providing software.

Cost of sales includes the cost of components and subcontracted manufacturing
related to hardware products. Gross profit as a percent of sales increased from
79% to 80% in the nine months ending September 30, 1997 and 1998 as a result of
the decrease in hardware sales.

Research and development expenses increased 2% from $3,919,000 in the nine
months ending September 30, 1997 to $4,009,000 in the nine months ending
September 30, 1998. This increase is a result of the merger with PureSpeech.

Selling, general, and administrative expenses increased 57% from $5,230,000 in
the nine months ending September 30, 1997 to $8,195,000 in the nine months
ending September 30, 1998. Additional sales personnel, operations and
administrative staff have been added to help support a growing customer base of
firms utilizing speech recognition technology with the addition of the
PureSpeech product line to VCS.

On April 14, 1998 VCS acquired 100 percent of the common stock and common stock
equivalents of PureSpeech in return for VCS stock. Pursuant to the terms of the
agreement, all shares of PureSpeech common and preferred stock outstanding
immediately prior to the closing of the Merger were converted into and exchanged
for 1,316,555 shares of VCS Common Stock. In addition, PureSpeech shareholder
debt assumed by VCS was converted into 322,878 shares of VCS common stock.
Options, warrants and other rights to acquire PureSpeech common stock were
converted to options and warrants to acquire 619,561 shares of VCS common stock.
The Merger was accounted for as a purchase with VCS acquiring PureSpeech in the
acquisition. The 


                                       9
<PAGE>   10


acquired in process research and development is expensed in the accompanying
financial statements.

The net operating loss (NOL) carryforwards of the Company expires from 1998 to
2012 and total approximately $36,620,000 as of September 30, 1998. The Company
has provided an allowance against its entire deferred tax asset relating
primarily to NOL carryforwards of approximately $12,450,000 since management
cannot determine that it is more likely than not that the deferred tax asset
will be realized. Approximately $1,225,000 in NOL carryforwards expired for the
year ended December 31, 1997. In connection with its merger and acquisition
activity the company and its predecessors have experienced ownership changes as
defined by Internal Revenue Code 382 the effect of such changes limits the use
of the Company's NOL in future years to approximately $1,405,000 annually. Any
portion of an NOL limited by IRC 382 not used in a given year can be carried
forward to subsequent years

Three Months Ended September 30, 1998 vs. September 30, 1997

Sales increased 83% from $3,689,000 during the three months ending September 30,
1997 to $2,021,000 during the three months ending September 30, 1998. Four
customers OKI Telecom, Inc., Dialogic Corporation, IBM, and Intel accounted for
19%, 18%, 14% and 14% respectively, of total sales for the three months ending
September 30, 1998. OKI Telecom, Glenayre, and Dialogic Corporation accounted
for 24%, 18% and 14%, respectively, of total sales for the three months ending
September 30, 1997. Royalty, development and license fees, which increased 157%
over the three months ending September 30, 1997, were 52 % of total revenues for
the three months ending September 30, 1998. Hardware sales, which increased 39%
over the three months ending September 30, 1997, were 42% of revenues in the
three months ending September 30, 1998.

Cost of sales includes the cost of components and subcontracted manufacturing
related to hardware products. Gross profit as a percent of sales increased from
78% to 84% for the three months ending September 30, 1997 and 1998 as a result
of the increased margin on software sales.

Research and development expenses decreased 1% from $1,323,000 for the three
months ending September 30, 1997 to $1,304,000 for the three months ending
September 30, 1998.

Selling, general, and administrative expenses increased 51% from $1,737,000 for
the three months ending September 30, 1997 to $2,620,000 for the three months
ending September 30, 1998. The increase is due to the introduction of the
Company's speech enabled auto-attendant product and additions to the selling,
marketing and administrative areas due to the PureSpeech acquisition.

On April 14, 1998 VCS acquired 100 percent of the common stock and common stock
equivalents of PureSpeech in return for VCS stock. Pursuant to the terms of the
agreement, all shares of PureSpeech common and preferred stock outstanding
immediately prior to the closing of the Merger were converted into and exchanged
for 1,316,555 shares of VCS Common Stock. 



                                       10
<PAGE>   11

In addition, PureSpeech shareholder debt assumed by VCS was converted into
322,878 shares of VCS common stock. Options, warrants and other rights to
acquire PureSpeech common stock were converted to options and warrants to
acquire 619,561 shares of VCS common stock. The Merger was accounted for as a
purchase with VCS acquiring PureSpeech in the acquisition. The acquired in
process research and development is expensed in the accompanying financial
statements.

LIQUIDITY AND CAPITAL RESOURCES

The Company's principal cash requirements to date have been to fund working
capital and capital expenditures in order to support its sales growth. Net
working capital at September 30, 1998 was $9,448,000. In the past, the Company's
working capital needs were financed primarily through cash flow from operations
and proceeds from the exercise of warrants and stock options.

At September 30, 1998, the Company held $6,461,000 in cash and cash equivalents.
Cash and cash equivalents are invested in institutional cash investment accounts
with preservation of capital being the primary consideration. All investments
currently have overnight liquidity. Historically, the Company's primary source
of liquidity has been the timely collection of its accounts receivable. The
average day's sales in accounts receivable was 97 days as of September 30, 1998.

The Company's inventory as of September 30, 1998 was approximately $655,000 net
of reserves of approximately $219,000 that have been established for
obsolescence.

The Company maintained $18,000 debt obligations as of September 30, 1998.

The Company's capital expenditures were $142,000 for the three months ended
September 30, 1998. The expenditures were primarily for computer equipment.

VCS believes that its existing sources of liquidity and funds generated by
operations will be sufficient to provide the capital resources necessary to
support its increased operating needs and finance continued growth in the
foreseeable future.
