Use of stress in an isolated word recognizer for French

An isolated word recognition system for French is now being developed. This effort is part of an ongoing collaborative project between Dragon Systems, Inc. and Lernout and Hauspie Speechproducts n.v. to port and adapt Dragon's large vocabulary speech recogition system for American English to five European languages: French, Spanish, German, Italian, and Dutch.

In the American English recognition system, performance is enhanced when the syllable stress is taken into account. Whether taking stress into account will enhance performance of the French recognizer is now being investigated. The preliminary French system recognizes 1000 words and is speaker adaptable. In developing the system, 3000 tokens from one native speaker of French have been collected. The capabilities of the recogni...
