摘要： A signal processing unit separates voice signals and non-voice audio signals contained in a mixed audio signal. The mixed audio signal is channel divided, and the voice signal portions of the channel divided mixed audio signal are detected and extracted at one output. Non-voice audio signals contained in the voice signal portions are predicted based on the non-voice audio signal portions of the mixed audio signal. The thus predicted non-voice audio signals are combined with extracted non-voice audio signals to obtain continuous non-voice audio signals which are output at a second output. Alternately, instead of extracting the voice signals from the mixed audio signal, the predicted non-voice signals are removed from the mixed audio signal to obtain the voice signals which are output on the first output.

摘要： An intermittent analog voice signal is coded which is contained in an analog mixed signal having the intermittent analog voice signal mixed with a background analog noise signal. An analog-to-digital converter receives the analog mixed signal and generates a coded output signal by digitizing the analog mixed signal when a control signal is applied thereto and does not generate a coded output signal when the control signal is not applied thereto. A voice signal detector means receives the analog mixed signal and detects periods during which the analog voice signal is present in the analog mixed signal. A control signal generator generates the control signal applied to the analog-to-digital converter during voice periods detected by the voice signal detector during which the analog voice signal is present in the analog mixed signal. The analog mixed signal is thus digitized by the analog-to-digital converter only during the voice periods detected by the voice signal detector.

摘要： A voice signal coding system includes a voice signal detector for receiving a mixed signal of an intermittent voice signal and background noise signal and for detecting the presence and absence of the voice signal contained in the mixed signal. A voice signal period detector is provided for detecting a voice signal period in which the voice signal is present. A coding period control circuit is coupled to the voice signal period detector for producing a coding period control signal during the voice signal period. A coding circuit receives and encodes the mixed signal in response to the coding period control signal. Thus, the mixed signal is coded in the coding circuit only during the voice signal periods.

摘要： A voice signal processor features a particular improvement of the S/N ratio. In the voice signal processor, the signal level in the voice band of a signal from which noise is cancelled to some extent is emphasized relative to the signal level in the noise band. Moreover, a cancellation factor is utilized in cancelling the noise, so that the voice level in the voice band is emphasized, or the noise level in the noise band is attenuated, achieving a better noise-suppressed voice signal.

摘要： A band division process including a Fourier transformation is performed for an inputted speech signal, thereby outputting spectrum signals of plural channels. A cepstrum analysis process is performed for the spectrum signals, and a peak of the obtained cepstrum is detected in response to the cepstrum analysis result. Thereafter, a speech signal interval of the inputted noisy speech signal is detected in response to the detected peak, and a noise is predicted in the speech signal in response to the detected speech signal interval. Then, the predicted noise is canceled in the spectrum signals thereby outputting noise-suppressed spectrum signals. Finally, the noise-suppressed spectrum signals are combined and are inverse Fourier-transformed, thereby outputting a noise-suppressed speech signal.
