SAPI-Compliant Software Uses Natural Language Technology for Fast, Intuitive Document Creation, Editing and Formatting; L&H Voice Xpress Plus Allows Dictation Directly into Microsoft® Word

BURLINGTON, MASS. -- April 28, 1998 -- Lernout & Hauspie (NASDAQ: LHSPF, EASDAQ: LHSP.ED) (L&H™), today shipped L&H Voice Xpress and L&H Voice Xpress Plus, the first software products to combine continuous speech recognition and Natural Language Technology (NLT) to provide document creation, formatting and editing capabilities. Industry influencers have heralded both products for their ability to let users employ conversational speech to execute formatting and editing commands in addition to providing a fast, accurate way to input text into documents. Today's competitive offerings do not have NLT and, as a result, require users to adhere to a strictly defined set of specific phrases for word processing command and control. In addition to supporting Microsoft's Speech Application Programming Interface (SAPI), L&H's Voice Xpress products incorporate specific extensions to Microsoft's speech platform that support NLT's advanced functionality. The estimated street prices for L&H Voice Xpress and for L&H Voice Xpress Plus, which include software on a CD-ROM, documentation, and a noise-canceling microphone, are $49.99 and $99.99, respectively.

"Continuous speech dictation products which employ natural language technology are much easier for users to learn and operate, permitting tasks to be processed in a more familiar and productive way," said Amy D. Wohl, president of Wohl Associates, a leading computer industry consulting firm in Narberth, Pennsylvania.

L&H Voice Xpress and L&H Voice Xpress Plus are L&H's first continuous dictation products aimed at the general consumer market and the first in the industry to employ L&H's breakthrough NLT. NLT is a form of artificial intelligence that allows L&H Voice Xpress and L&H Voice Xpress Plus to intelligently interpret users' commands and format a document as intended. Because NLT makes editing and formatting more intuitive, users can access much of the functionality found in Microsoft Word with voice commands. Formatting and editing by voice is easier to learn and more efficient than utilizing the keyboard or mouse because users can easily locate extensive word processing commands without spending time searching through menus and toolbars.

"L&H has been widely recognized for bringing high-quality voice recognition to key vertical markets where speech technology is a natural fit, such as medical reporting, computer telephony, automotive electronics, and other areas," said Koen Bouwers, president of L&H's dictation division. "Now, with the launch of the L&H Voice Xpress products, we are bringing the power of speech—complete with Natural Language command and control—to all desktops. The functionality built into these products will enable a new era of desktop computing for a broad consumer audience."

User Benefits

Most users who regularly draft documents on a PC will immediately derive benefits from L&H Voice Xpress and L&H Voice Xpress Plus, regardless of their skill level. Both content and commands can be spoken at a natural, conversational pace— enhancing productivity and boosting the performance of the average user. With L&H Voice Xpress users can achieve dictation rates of up to 140 words per minute. Users can issue editing and formatting commands while dictating because both products are modeless - meaning users do not have to "tell" the program whether their next words will be dictation or command phrases.

L&H Voice Xpress Plus gives users the added capability of dictating directly into and controlling Microsoft Word. With L&H Voice Xpress Plus, users can access the breadth of command functionality found in Word's various toolbars and menus by issuing flexible, natural commands.

"L&H's new Voice Xpress Plus product helps users realize the power of Word 97 with natural, intuitive voice commands," said Dennis Tevlin, director of Office Marketing at Microsoft Corporation. "Users can now create, edit and format Microsoft Word 97 documents using the power of speech."
