Rotation-Robust Beamforming Based on Sound Field Interpolation with Regularly Circular Microphone Array

Yukoh Wakabayashi, Kouei Yamaoka, Nobutaka Ono

ICASSP 2021accepted

In this paper, we present a novel framework of beamforming robust for a microphone array rotation. In most array signal processing methods, the time-invariant transfer system from a source to a microphone is assumed for calculating a spatial filter. This assumption makes it difficult to use the micr…

Phase reconstruction method based on time-frequency domain harmonic structure for speech enhancement

Yukoh Wakabayashi, Takahiro Fukumori, Masato Nakayama, Takanobu Nishiura, Yoichi Yamashita

ICASSP 2017accepted

Speech enhancement in noisy environments has been widely investigated by modifying only the amplitude spectrum of the speech signal, while the phase spectrum, which is regarded as an unimportant feature, is ignored. However, it has recently been reported that the phase spectrum plays an important ro…
