Multichannel speech enhancement using Bayesian spectral amplitude estimation
This paper introduces two shon-time spectral amplitude estimators for speech enhancement with multiple microphones. Based on joint Gaussian models of speech and noise Fourier coefficients the clean speech amplitudes are estimated with respect to the MMSE or the MAP criterion. The estimators outperform single microphone minimum mean square amplitude estimators when the speech is highly correlate...
متن کاملImproved Speech-Presence Uncertainty Estimation Based on Spectral Gradient for Global Soft Decision-Based Speech Enhancement
In this paper, we propose a speech-presence uncertainty estimation to improve the global soft decision-based speech enhancement technique by using the spectral gradient scheme. The conventional soft decision-based speech enhancement technique uses a fixed ratio (Q) of the a priori speech-presence and speech-absence probabilities to derive the speech-absence probability (SAP). However, we attemp...
متن کاملMicrophone Array Speech Enhancement by Bayesian Estimation of Spectral Amplitude and Phase
Microphone arrays provide new opportunities for noise reduction and speech enhancement. This paper presents a novel decomposition of the estimation problems for short-time spectral amplitude (STSA), log STSA, and phase in the Bayesian estimation framework. The decomposition is based on the notion of sufficient statistics for the microphone array case. It nicely generalizes the wellknown single-...
متن کاملMultichannel Direction-Independent Speech Enhancement Using Spectral Amplitude Estimation
This paper introduces two short-time spectral amplitude estimators for speech enhancement with multiple microphones. Based on joint Gaussian models of speech and noise Fourier coefficients, the clean speech amplitudes are estimated with respect to the MMSE or the MAP criterion. The estimators outperform single microphone minimum mean square amplitude estimators when the speech components are hi...
متن کاملSpeech Enhancement Based on a Microphone Array and Log-Spectral Amplitude Estimation
1. Introduction Microphone array systems are often used for high quality hands-free communication in reverberant and noisy environments [1]. Compared to single microphone systems, a substantial gain in performance is obtainable due to the spatial filtering capability to suppress interfering signals coming from undesired directions. In cases of spatially incoherent noise fields, beamforming alon...
