Abstract:
1. An Automatic Speech Recognition (ASR) method comprising: extracting utterances from each of one or more audio streams, each audio stream being associated with a particular context; one or more computers extracting said utterances; generating textual candidates for each extracted utterance, one or more utterances having a plurality of textual candidates generated as potential matches; winnowing potential matches automatically with a context model within each particular context to adjust the likelihood of potential matches; selecting a single textual candidate for said each extracted utterance as a match, any selected textual candidate not having been previously matched for the current context being a new match; and updating said context model responsive to each match, wherein updating either adds the selected said textual candidate to said context model for the new match, or increases the likelihood for the previously selected said single textual candidate for the same particular context in the updated said context model, and said updated context model is used for winnowing subsequently extracted utterances.
