  • Distributed speech recognition with codec parameters
    Patent number: 7050969
    Abstract: A method extracts speech recognition features from a speech signal coded as a bitstream. First, the bitstream is decoded to recover linear predictive coding filter parameters, and a residual signal. Then, the linear predictive coding filter parameters and the residual signal are discriminatively combined into speech recognition features.
    Type: Grant
