SOUND COLLECTION SYSTEM AND SOUND DISPLAY METHOD

摘要

PROBLEM TO BE SOLVED: To provide a sound collection system for confirming how a voice collected from a voice input part is suppressed for each sound source. SOLUTION: This sound collection system includes: a microphone array configured of two or more microphones; and a processing part for converting a signal to be output from the microphone array. The processing part includes: a sound source separation part for separating a signal output from the microphone in each direction where a sound source exists; a noise removal processing part for removing a noise from a signal output from the microphone array; and a direction-categorized residual signal calculation part for calculating the direction-categorized volume of the residual signal based on the signal output from the sound source separation part and the residual signal output from the noise removal processing part. The sound collection system includes a suppression volume display part for displaying the volume of the direction-categorized residual signal based on the calculation result by the direction-categorized residual signal calculation part.
