  • Publication number: 20050031312
    Abstract: This invention provides a method and apparatus for signal reproduction that can simultaneously reproduce N (N?2) signals which are previously multiplexed, and simultaneously reproduce N independent signals. This apparatus selectively inputs the independent N coded signals in time division, adds the corresponding stream information to the selected input signal among N kinds of stream information for identifying the input signals, detects the stream information from the respective input signal, decodes the respective input signal by a decoding method corresponding to the respective input signal, which is decided based on the detected stream information, and outputs the decoded signal.

  • Patent number: 5835890
    Abstract: In a speaker adaptation method for speech models, input speech is transformed to a feature parameter sequence like a cepstral sequence, and N model sequences of maximum likelihood for the feature parameter sequence are extracted from speaker-independent speech HMMs by an N-best hypothesis extraction method. The extracted model sequences are each provisionally adapted to maximize its likelihood for the feature parameter sequence of the input speech while changing the HMM parameters of each sequence, and that one of the provisionally adapted model sequences which has the maximum likelihood for the feature parameter sequence of the input speech is selected and speech models of the selected sequence are provided as adapted HMMs of the speaker to be recognized.

  • Patent number: 5721808
    Abstract: Noise-resistant speech HMMs are composed by: recording noise in the environment of utterance (S.sub.1); preparing HMMs of the noise (S.sub.2); transforming the output probability distribution of each of the noise HMMs and speech HMMs prepared from speech unaffected by noise and multiplicative distortion to a linear spectral domain (S.sub.31); multiplying the speech HMM distribution in the linear spectral domain by a multiplicative distortion W that is an unknown variable (S.sub.321); convoluting the multiplied value and the noise HMM distribution in the linear spectral domain (S.sub.322); inversely transforming the convoluted value to the original domain of the speech HMM (S.sub.33) to compose incomplete noise-resistant speech HMMs each containing multiplicative distortion as an unknown variable (S.sub.
