Speech enhancement using a wiener denoising technique and musical noise reduction
نویسندگان
چکیده
Speech enhancement methods using spectral subtraction have the drawback of generating an annoying residual noise with musical character. In this paper a frequency domain optimal linear estimator with perceptual post filtering is proposed which incorporates the masking properties of the human auditory system to make the residual noise distortion inaudible. The performance of the proposed enhancement algorithm is evaluated by the Segmental SNR, Log Spectral Distance (LSD) and Perceptual Evaluation of Speech Quality (PESQ) measures under various noisy environments and yields better results compared to the Wiener denoising technique.

Speech Enhancement Perceptual Modification Of
A speech denoising technique based on subband noise estimation and a perceptual modification of Wiener filtering is proposed. The noisy speech is first decomposed into critical band signals by an auditory filterbank and the denoising is carried out on the subband signals. The time varying subband noise variance required for denoising is estimated by tracking the minimum variance of the subband ...
متن کاملAn Adaptive Noise Estimation Algorithm for Speech Enhancement
A fast and robust speech noise estimation technique is proposed. The noisy speech is decomposed using a critical-band-rate filterbank so that a perceptual modification of Wiener filtering can be applied in speech denoising. The subband noise estimate is updated adaptively using a smoothing parameter that depends on the estimated signal-to-noise ratio (SNR). This noise estimation technique can g...
متن کاملA New Speech Enhancement Technique to Reduce Residual Noise Using Perceptual Constrained Spectral Weighted Factors
This paper deals with residual musical noise which results from the perceptual speech enhancement type algorithms and especially using wiener filtering approach. Perceptual speech enhancement techniques perform better than the non perceptual techniques, most of them still return a trouble residual musical noise. This is due to that only noise above the noise masking threshold (NMT) is filtered ...
متن کاملSpeech Enhancement Using Gaussian Mixture Models, Explicit Bayesian Estimation and Wiener Filtering
Gaussian Mixture Models (GMMs) of power spectral densities of speech and noise are used with explicit Bayesian estimations in Wiener filtering of noisy speech. No assumption is made on the nature or stationarity of the noise. No voice activity detection (VAD) or any other means is employed to estimate the input SNR. The GMM mean vectors are used to form sets of over-determined system of equatio...
متن کاملPerceptual wavelet adaptive denoising of speech
This paper introduces a novel speech enhancement system based on a wavelet denoising framework. In this system, the noisy speech is first preprocessed using a generalized spectral subtraction method to initially lower the noise level with negligible speech distortion. A perceptual wavelet transform is then used to decompose the resulting speech signal into critical bands. Threshold estimation i...
