Speech Enhancement using Modified Spectral Subtraction Algorithm
نویسنده
چکیده
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 ways for providing best quality of speech signal aimed at speech enhances using Modified Spectral Subtraction algorithms (MSS). The scope of the proposed solution is to improve the SNR value of audio signal as well as to reduce completely background noise without affecting signal power. This paper defines the modified spectral subtraction method to estimate noise in non-stationary speech environment. Finally, we have discussed some of the performance parameters such as: time required as number of samples increases and Improved SNR.

متن کاملA Modified LIMA Framework for Spectral Subtraction Applied to In-Car Speech Recognition
In noisy environments, speech recognition accuracy degrades significantly. Speech enhancement algorithms have been designed to overcome this, however solutions to date have not been optimal for speech recognition especially for non-stationary noise like that in a car. Recently, a likelihood-maximising (LIMA) criteria has been applied to speech enhancement techniques. This paper analyses the sui...
