Speech Enhancement using a Modified Apriori SNR and Adaptive Spectral Gain Control
A new approach to single channel speech enhancement is proposed using a modified a priori SNR and spectral gain control. The proposed approach is first directed toward finding self adaptive averaging factor to estimate the apriori SNR. Next, spectral gain is reduced in order to suppress effects of the noise in the speech absent frames. Further, in the speech present frames, in order to reduce s...
متن کاملA Modified Speech Enhancement Using Adaptive Gain Equalizer with Non linear Spectral Subtraction for Robust Speech Recognition
In this paper we present an enhanced noise reduction method for robust speech recognition using Adaptive Gain Equalizer with Non linear Spectral Subtraction. In Adaptive Gain Equalizer method (AGE), the input signal is divided into a number of subbands that are individually weighed in time domain, in accordance to the short time Signal-to-Noise Ratio (SNR) in each subband estimation at every ti...
متن کاملSpeech Enhancement using an Adaptive Gain Equalizer
This paper presents a noise reduction method for speech communication where the input signal is divided into a number of subbands that are individually weighted in time domain according to the short time Signal-to-Noise Ratio estimate (SNR) in each subband at every time instant. Instead of focusing on suppression the noise, the method is focusing on speech enhancement. The method has proven to ...
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 by Modified Convex Combination of Fractional Adaptive Filtering
This paper presents new adaptive filtering techniques used in speech enhancement system. Adaptive filtering schemes are subjected to different trade-offs regarding their steady-state misadjustment, speed of convergence, and tracking performance. Fractional Least-Mean-Square (FLMS) is a new adaptive algorithm which has better performance than the conventional LMS algorithm. Normalization of LMS ...
