  • System and methods for using transcripts to train an automated directory assistance service
    Patent number: 7447636
    Abstract: An automated directory assistance (130) includes a training system (210). and a directory assistance system (220). The training system (210) trains and maintains the directory assistance system (220). The training system (210) includes a transcription module (310), a speech grammar estimation module (330), a listings statistics estimation module (340), and a required words determination module (350). The transcription module (310) obtains transcripts relating to directory service requests. The speech grammar estimation module (330) creates an n-gram grammar for multiple telephone numbers from the transcripts. The listings statistics estimation module (340) identifies words used to refer to each of the telephone numbers from the transcripts. The required words determination module (350) identifies at least one word that is required to request each of the telephone numbers from the transcripts.

  • Systems and methods for using one-dimensional gaussian distributions to model speech
    Patent number: 7295978
    Abstract: A system for recognizing speech receives an input speech vector and identifies a Gaussian distribution. The system determines an address from the input speech vector (610) and uses the address to retrieve a distance value for the Gaussian distribution from a table (620). The system then determines the probability of the Gaussian distribution using the distance value (630) and recognizes the input speech vector based on the determined probability (640).
