Self-produced speech enhancement and suppression method with wearable air- and body-conductive microphones

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a self-produced speech enhancement and suppression method for multichannel signals recorded with both air- and body-conductive microphones. In processing auditory sound signals recorded with wearable microphones for memorizing conversation and acoustic scenes and events in daily life, source separation is a promising technique as only a mixing of various sound sources can be observed. To separate the recorded signals into self-produced speech, i.e., user's own speech and ambient environmental sounds, we propose a self-produced speech enhancement and suppression method using not only air-conductive microphones to record multichannel air-conducted signals but also body-conductive microphones to record body-conducted signals. A separation filter applied to the multichannel air-conducted signals is estimated while effectively using the body-conducted signals dominantly including self-produced speech components. We conduct an experimental evaluation to investigate the effectiveness of the proposed method, thereby demonstrating that the proposed method outperforms the conventional method using only the air-conductive microphones.
