WIPO Patent Application WO/2021/085174
Kind Code:
A1
Abstract:
The present invention pertains to a voice processing device and a voice processing method with which it is possible to minimize acoustic feedback more assuredly. Provided is a voice processing device equipped with a signal processing unit that processes a voice signal picked up by a microphone, that compares, with a given threshold, an index relating to the amount of wraparound of a sound going into the microphone according to a voice signal outputted from a speaker, and that performs a threshold value determination. Accordingly, it is possible to minimize acoustic feedback more assuredly. The present invention is applicable to, for example, a sound amplification system that performs off-microphone sound amplification.
