The language is composed using phonemes which is easy to separate in an environment of noise and disturbing sound. An acoustic signal comprising phonemes which is easy to separate in an environment of noise and disturbing sound fed to the acoustic signal analyzer is analyzed therein, and from the result of the analysis, the tone name is recognized in the tone name identifier, and after the tone name is recognized as a prescribed sentence, the sentence is fed to the utterance generator. Corresponding to these operations, the utterance generator generates a prescribed time series composed of tone names comprising phonemes which is easy to separate in an environment of noise and disturbing sound, and inputs it to the acoustic signal generator. The acoustic signal generator synthesizes an acoustic signal which corresponds to the time series and outputs the acoustic signal.
A speech recognition system for recognizing speech in an environment of noise and disturbing sound, comprising:
A speech synthesis system for synthesizing speech in an environment of noise and disturbing sound, comprising:
A speech recognition and synthesis system for recognizing and synthesizing speech in an environment of noise and disturbing sound, which system is provided with an analysis means for analyzing a sound signal including at least one of phonemes and time series of phonemes, and the sound signal further including at least one of noise and disturbing sound, and the system also being provided with a recognition means for recognizing a signal representative of said phonemes and time series of phonemes, wherein the analysis means analyzes the sound signal by performing a frequency analysis and the result of the frequency analysis is treated as a time series in determining if a feature point of the sound signal moves in a prescribed direction in a frequency analysis space relative to a time index axis for a prescribed time period, and wherein the analysis means separates said noise and disturbing sound from said phonemes and time series of phonemes based upon said analyzing and outputs a signal representative of said phonemes and time series of phonemes to the recognition means, and the system also being provided with a synthesis means coupled to said recognition means for synthesizing speech.
A method for separation of speech from noise and other disturbing sound, comprising the steps of:
