SELF-FAULT DETECTION SYSTEM AND METHOD FOR MICROPHONE ARRAY AND AUDIO-BASED DEVICE

摘要

Disclosed herein is a self-fault detection system and method in a microphone array system, in which features for self-fault detection of a microphone array are formed using internal values of a voice activity detector (VAD) with respect to audio signals respectively outputted from a plurality of microphones, the features generated with respect to each of the microphones are mutually and automatically compared without a special reference signal, thereby self-detecting fault microphones.
