Abstract
PURPOSE: To prevent malfunction due to influences of a breathing tone and ambient noise by detecting variation in short-period spectrum.
CONSTITUTION: This unit is provided with voice detection part 20 which detects a proposed voice period by examining an input signal wave, variation examination part 40 which discriminates and outputs information on whether or not the proposed voice period is for a significant voice by detecting variation in short-period spectrum in the proposed voice period, and discrimination part 30 which functions to discriminate a signal in the proposed voice period as a voice pattern and rejects the discrimination result when it is indicated by the signal from examination part 40 that the proposed period is not for the significant voice. As a result, a time-averaged spectrum variation is obtained and it can be avoided that a breathing tone and ambient tone continuing for a long time are approved as a significant voice.
