- Voice-based interaction generates a lot of interest for natural
human–robot interaction. Auditory information from microphones is an
essential clue for a robot’s attention to a person. Fault detection of microphones
is required in order to improve the reliability of the voice-based
human–robot interaction. This paper proposes a new approach for realtime
fault detection in a microphone array in conversation without a calibration
signal and a known sound source position by the intercorrelation of
features in voice activity detection. The approach is successfully applied to
a six-microphone system, and experimental results show an average fault
detection of 97.6%.
