Testing some essential parameters of a word recognizer used in car noise

Mats Blomberg, Kjell Elenius

A speaker-dependent, pattern-matching word recognition system using dynamic programming has been modified to improve the performance in noise. Problems with word detection and noise compensation have been addressed by using a close-talk microphone and a "noise addition" method. The reference templates are recorded in relative silence. The additional environmental noise during the recognition phase is measured and is "added" to the reference templates before using them for template matching. The recognition performance has been tested in moving cars with references recorded in parked cars. Recordings of six male speakers have been evaluated in this report in an effort to test the sensitivity of the recognition system to some essential parameters.
