A priori SNR estimation and noise estimation for speech enhancement. [PDF]
EURASIP J Adv Signal Process, 2016 A priori signal-to-noise ratio (SNR) estimation and noise estimation are important for speech enhancement. In this paper, a novel modified decision-directed (DD) a priori SNR estimation approach based on single-frequency entropy, named DDBSE, is proposed.
