  • Patent number: 7133827
    Abstract: A new word model is trained from synthetic word samples derived by Monte Carlo techniques from one or more prior word models. The prior word model can be a phonetic word model and the new word model can be a non-phonetic, whole-word, word model. The prior word model can be trained from data that has undergone a first channel normalization and the synthesized word samples from which the new word model is trained can undergo a different channel normalization similar to that to be used in a given speech recognition context. The prior word model can have a first model structure and the new word model can have a second, different, model structure. These differences in model structure can include, for example, differences of model topology; differences of model complexity; and differences in the type of basis function used in a description of such probability distributions.

  • Publication number: 20040260547
    Abstract: A method of processing speech in a noisy environment includes determining, upon a wake-up command, when the environment is too noisy to yield reliable recognition of a user's spoken words, and alerting the user that the environment is too noisy. Determining when the environment is too noisy includes calculating a ratio of signal to noise. The signal corresponds to of an amount of energy in the spoken utterance, and the noise corresponds to an amount of energy in the background noise. The method further includes comparing the signal to noise to a threshold.

  • Publication number: 20040210438
    Abstract: A method for speech recognition. The method uses a single pronunciation estimator to train acoustic phoneme models and recognize utterances from multiple languages. The method includes accepting text spellings of training words in a plurality of sets of training words, each set corresponding to a different one of a plurality of languages. The method also includes, for each of the sets of training words in the plurality, receiving pronunciations for the training words in the set, the pronunciations being characteristic of native speakers of the language of the set, the pronunciations also being in terms of subword units at least some of which are common to two or more of the languages. The method also includes training a single pronunciation estimator using data comprising the text spellings and the pronunciations of the training words.
