A barge-in free spoken dialogue interface using sound field control and microphone array is proposed. In the conventional spoken dialogue system using an acoustic echo canceller, it is indispensable to estimate a room transfer function, especially wh

This paper proposes a method of monaural sound source separation by clustering based on the similarity of basis vectors decomposed by Non-negative Matrix Factorization (NMF). In the proposed method, the basis vectors are clustered on the assumption t

In this study, we propose a new method for improving speech intelligibility in a public space such as station concourse that focuses on the difference in ease of listening due to the individuality of a speaker's voice. The proposed method evaluates t

In the present paper, we propose a method of reference signal extraction for a semi-adaptive sound reproduction system based on semi-blind source separation under a noisy environment. Since the fluctuation of room transfer functions degrades the repr

In this paper, we propose a computationally efficient method of compensating temperature for the transaural stereo. The conventional method can be used to estimate the change in impulse responses caused by the fluctuation of temperature with high acc

In this paper, we describe a new interface for a barge-in free spoken dialogue system combining multichannel sound field control and beamforming, in which the response sound from the system can be canceled out at the microphone points. The convention
