A priori SAP estimator based on the magnitude square coherence for dual-channel microphone system
ICASSP 2015accepted
In this paper, we present a time-frequency (TF)-dependent a priori speech absence probability (SAP) estimator utilizing the magnitude square coherence (MSC) between two microphone signals. It is shown that the normalized SNR can be numerically computed from the MSC by solving a quadratic equation. B…
