SYSTEM AND METHOD OF SPEECH RECOGNITION TRAINING BASED ON CONFIRMED SPEAKER UTTERANCES

摘要

An interactive speech recognition training process and system is disclosed. A speech recognition process is applied to a received speaker utterance. Utterance data are matched by the system with data in a grammar database and the speaker is requested to confirm a determined match. If the system determines from the speaker's response that the match is not confirmed, a negative score is assigned to the utterance data. If the match is determined by the system to be confirmed, a positive score is assigned to the utterance data. Scores for a plurality of such speaker utterances are accumulated in a log file, the accumulated scores used to adjust acoustic models for the grammar database.
