Title:
SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/220768
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent deterioration of voice extraction performance when the positions of multiple microphones are changed. The signal processing device pertaining to the present invention is provided with a voice extraction unit for extracting voice from signals from multiple microphones. When the positions of multiple microphones are changed to positions where other microphone were previously located, the voice extraction unit uses the signal from each of the multiple microphones as signals from the other microphones. As a result, the influence of the positional change of each microphone on the voice extraction can be cancelled.
