The voice signal processor according to the present invention features 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 relatively 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. <IMAGE> |
