Power Spectral Density Error Analysis of Spectral Subtraction Type of Speech Enhancement Methods
A theoretical framework for analysis of speech enhancement algorithms is introduced for performance assessment of spectral subtraction type of methods. The quality of the enhanced speech is related to physical quantities of the speech and noise (such as stationarity time and spectral flatness), as well as to design variables of the noise suppressor. The derived theoretical results are compared ...
متن کاملA Comparison Study of Spectral Subtraction Speech Enhancement Methods
Spectral subtraction is a widely employed method for the suppression of additive noise in speech signals. Several variants of the basic approach have been proposed over the years to address certain shortcomings, chiefly the quality of the remnant noise and its trade-off with speech distortion. In this paper, we present a unified view of the various forms of the spectral subtraction speech enhan...
متن کاملFrequency Depended Spectral Subtraction For Speech Enhancement
The corruption of speech due to presence of additive background noise causes severe difficulties in various communications environments. This paper addresses the problem of reduction of additive background noise in speech. The proposed approach is a frequency dependent speech enhancement method based on the proven spectral subtraction method. Most implementations and variations of the basic spe...
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 کاملModified Spectral Subtraction Based Speech Enhancement
The one-microphone speech enhancement, (SE) algorithm as a modification of the extended spectral subtraction (SS) method (ESS) [1] is presented in this paper. The algorithm can be used for the reduction of additive stationary and quasi-stationary colored broad-band noise in noisy speech in hands-free communication terminals as well as in a number of other applications. The achieved noise reduct...
