End-to-End Integration of Speech Recognition, Dereverberation, Beamforming, and Self-Supervised Learning Representation
Yoshiki Masuyama, Xuankai Chang, Samuele Cornell +2
Self-supervised learning representation (SSLR) has demonstrated its significant effectiveness in automatic speech recognition (ASR), mainly with clean speech. Recent work pointed o…
Inverse-free Online Independent Vector Analysis with Flexible Iterative Source Steering
Taishi Nakashima, Nobutaka Ono
In this paper, we propose a new online independent vector analysis (IVA) algorithm for real-time blind source separation (BSS). In many BSS algorithms, the iterative projection (IP…
Joint Analysis of Acoustic Scenes and Sound Events with Weakly labeled Data
Shunsuke Tsubaki, Keisuke Imoto, Nobutaka Ono
Considering that acoustic scenes and sound events are closely related to each other, in some previous papers, a joint analysis of acoustic scenes and sound events utilizing multita…
Joint Optimization of Sampling Rate Offsets Based on Entire Signal Relationship Among Distributed Microphones
Yoshiki Masuyama, Kouei Yamaoka, Nobutaka Ono
In this paper, we propose to simultaneously estimate all the sampling rate offsets (SROs) of multiple devices. In a distributed microphone array, the SRO is inevitable, which deter…
Estimation of Consistent Time Delays in Subsample via Auxiliary-Function-Based Iterative Updates
Kouei Yamaoka, Yukoh Wakabayashi, Nobutaka Ono
In this paper, we propose a new algorithm for the estimation of multiple time delays (TDs). Since a TD is a fundamental spatial cue for sensor array signal processing techniques, m…
