A Priori SNR Estimation Using Discriminative Non-Negative Matrix Factorization

Abstract: A priori signal-to-noise ratio (SNR) contains critical information about the single-channel mixture of a speech and noise signal, and can be used by speech enhancement algorithms. In this ...

A Priori SNR Estimation Using Air- and Bone-Conduction Microphones

Abstract: This paper proposes an a priori signal-to-noise ratio (SNR) estimator using an air-conduction (AC) and a bone-conduction (BC) microphone. Among various ways of combining AC and BC ...
