  • Method and system for dynamic speech recognition using free-phone scoring
    Patent number: 6243678
    Abstract: A system performing a speech recognition process requests and receives a claim of identity. The system accesses a customer database and generates a subword spelling of a stored text string where the text string includes predetermined information. The system accesses a subword model database to construct a subword model comprising a series of phonemes. The system requests and receives a speech utterance. A free-phone model of the speech utterance is generated independently of the information stored in the customer database. The system generates a free-phone score. The system generates a word score. The system determines whether the speech utterance matches the stored text string based on the free-phone score and the word score.
