Speech 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...
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 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...
متن کاملModulation domain spectral subtraction for speech enhancement
In this paper we investigate the modulation domain as an alternative to the acoustic domain for speech enhancement. More specifically, we wish to determine how competitive the modulation domain is for spectral subtraction as compared to the acoustic domain. For this purpose, we extend the traditional analysis-modification-synthesis framework to include modulation domain processing. We then comp...
