Method and system for speech recognition based on phonetic transcriptions

摘要

A method and system for recognizing a speech utterance as a predetermined unit of speech. The method comprises generating a free-phone model of the speech utterance and calculating a free-phone score representing the likelihood that the free-phone model accurately represents the speech utterance, the method also comprises determining whether the speech utterance matches the predetermined unit of speech based upon its score. In an alternative embodiment, the determination of whether the speech utterance matches the predetermined unit of speech is based upon both a word score and the free-phone score. <IMAGE>
