A priori SNR estimation and noise estimation for speech enhancement
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. DDBSE replaces the fixed weighting factor in the DD approach with an adaptive one calculated according to change of single-frequency entropy....
متن کاملImproved a Priori SNR Estimation for Speech Enhancement Incorporating Speech Distortion Component
The well known decision-directed (DD) approach drastically limits the level of musical noise, but the estimated a priori SNR matches the previous frame rather than the current one. Plapous introduced a novel method called two-step noise reduction (TSNR) technique to refine the a priori SNR estimation of the DD approach. However, the performance of this method depends on the accurateness of the ...
متن کاملSpeech enhancement using super-Gaussian speech models and noncausal a priori SNR estimation
Existing supergaussian speech models in the short-time Fourier transform domain are based on the assumption that distinct spectral components are statistically independent. The corresponding minimum mean-square error (MMSE) spectral estimators require an estimator for the a priori SNR. Unfortunately, the latter is often obtained by the decision-directed approach of Ephraim and Malah, which reli...

a r t i c l e i n f o a b s t r a c t A priori SNR A posteriori SNR SNR cells Spectral distortion Most speech enhancement methods based on short-time spectral modification are generally expressed as a spectral gain depending on the estimate of the local signal-to-noise ratio (SNR) on each frequency bin. Several studies have analyzed the performance of a priori SNR estimation algorithms to impro...
متن کاملNoise estimation for efficient speech enhancement and robust speech recognition
Different approaches of minima tracking based noise estimation algorithms are compared and modifications increasing their efficiency are proposed. Estimated noise is used by noise suppression algorithm that is a part of speech recognition system. Moreover, the algorithms are developed to be applied in feature extraction of Distributed Speech Recognition (DSR). Therefore we propose such modifica...
