Refinement of Direction of Arrival Estimators by Majorization-Minimization Optimization on the Array Manifold
Robin Scheibler, Masahito Togami
We propose a generalized formulation of direction of arrival estimation that includes many existing methods such as steered response power, subspace, coherent and incoherent, as we…
Label-Synchronous Speech-to-Text Alignment for ASR Using Forward and Backward Transformers
Yusuke Kida, Tatsuya Komatsu, Masahito Togami
This paper proposes a novel label-synchronous speech-to-text alignment technique for automatic speech recognition (ASR). The speech-to-text alignment is a problem of splitting long…
Joint Dereverberation and Separation with Iterative Source Steering
Taishi Nakashima, Robin Scheibler, Masahito Togami +1
We propose a new algorithm for joint dereverberation and blind source separation (DR-BSS). Our work builds upon the IRLMA-T framework that applies a unified filter combining dereve…
