Distributed multichannel speech enhancement with minimum mean-square error short-time spectral amplitude, log-spectral amplitude, and spectral phase estimation
In this paper, the authors present optimal multichannel frequency domain estimators for minimum mean-square error (MMSE) short-time spectral amplitude (STSA), log-spectral amplitude (LSA), and spectral phase estimation in a widely distributed microphone configuration. The estimators utilize Rayleigh and Gaussian statistical models for the speech prior and noise likelihood with a diffuse noise f...
متن کاملBeta-order minimum mean-square error multichannel spectral amplitude estimation for speech enhancement
In this paper, the minimum mean-square error (MMSE) ˇ-order estimator for multichannel speech enhancement is proposed. The estimator is an extension of the single-channel MMSE ˇ-order and multichannel MMSE short-time spectral amplitude estimators using Rayleigh and Gaussian distributions for the statistical models under the assumption of a diffuse noise field where the noise is estimated indepe...
متن کاملSpeech Prior Estimation for Generalized Minimum Mean-Square Error Short-Time Spectral Amplitude Estimator
In this paper, we introduce a generalized minimum meansquare error short-time spectral amplitude estimator with a new prior estimation of the speech probability density function based on momentcumulant transformation. From the objective and subjective evaluation experiments, we show the improved noise reduction performance of the proposed method. key words: generalized MMSE STSA estimator, spee...
متن کاملBlind Speech Prior Estimation for Generalized Minimum Mean-Square Error Short-Time Spectral Amplitude Estimator
In this paper, to achieve high-quality speech enhancement, we introduce the generalized minimum mean-square error shorttime spectral amplitude estimator with a new blind prior estimation of the speech probability density function (p.d.f.). To deal with various types of speech signals with different p.d.f., we propose an algorithm of speech kurtosis estimation based on moment-cumulant transforma...
متن کاملSpeech Enhancement Based on a Combination of Spectral Subtraction and a Minimum Mean-Square Error Short-Time Log-Spectral Amplitude Estimator in Wavelet Domain
The corruption of speech due to presence of additive background noise causes severe difficulties in various communication environments. This paper presents a novel noise reduction technique based upon a combination of cascaded spectral subtraction and minimum mean-square error short-time log-spectral amplitude estimator methods in the wavelet domain. The scheme’s performance is illustrated by e...
