Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose an acoustic distance measurement method based on interference of speech presented by a dialogue system. The proposed method estimates the distances to talkers in speech segments using the results of voice activity detection. In addition, since ambient noise degrades the performance of acoustic distance measurement in real environments, the proposed method makes use of an acoustic distance measurement method based on subtraction and an acoustic distance measurement method based on the calibration and whitening processing. Finally, we confirmed the effectiveness of the proposed method through experiments in real environments.
