A family of Bayesian STSA estimators for the enhancement of speech with correlated frequency components

Abstract

In Bayesian short-time spectral amplitude (STSA) estimation for speech enhancement, the spectral components are traditionally assumed uncorrelated. However, this assumption is inexact since some correlation is present in practice. We thus investigate a multi-dimensional STSA estimator that assumes correlated frequency components. Since the closed-form… (More)
