Speech Enhancement in Presence of Noise using Spectral Subtraction and Wiener Filter
The process of suppressing the back ground noise in speech signals can be improved by subtraction of an estimate of the average noise spectrum from the noisy signal spectrum. The main objective of this paper is to implement and evaluate speech enhancement techniques based on spectral subtraction methods in presence of noise. The two techniques discussed in this paper are spectral subtraction fi...
متن کاملSpeech Enhancement using Modified Spectral Subtraction Algorithm
The objective of Speech Enhancement is to improve the quality of audio signal that are degraded speech signal used in various application i.e. VOIP, hearing aids, teleconferencing systems. Currently the Speech Enhancement deals with several problems to improve requirements of speech recognition such as background noise that is presented in speech signal. The proposed work introduces alternative...
متن کاملSpeech enhancement using critical band spectral subtraction
This paper proposes a new enhancement technique for the enhancement of broadband noise corrupted speech. The technique exploits the human auditory systems inability to distinguish between individual frequency components within critical frequency bands. Spectral subtraction is used and the spectrum is considered as critical frequency bands rather than individual frequency components. The propose...

1 MULTI-CHANNEL SPEECH ENHANCEMENT IN A CAR ENVIRONMENT USING WIENER FILTERING AND SPECTRAL SUBTRACTION Joerg Meyer and Klaus Uwe Simmer University of Bremen, FB{1, Dept. of Telecommunications P.O. Box 33 04 40, D-28334 Bremen, Germany, Fax: +(49)-421/218-3341, e-mail: [email protected] ABSTRACT This paper presents a multichannel-algorithm for speech enhancement for hands{free telephone ...
متن کاملMultichannel MMSE Wiener Filter Using Complex Real and Imaginary Spectral Coefficients for Distributed Microphone Speech Enhancement
In this paper, the authors propose a frequency domain multichannel Wiener filter for distributed microphone speech enhancement using acoustic arrays. The current state-of-the-art single channel estimators achieve noticeable performance gains using the to-noise ratio (SNR) and segmental signal-to-noise ratio (SSNR) objective measures, which measure noise reduction, but only achieve marginal perf...
