Real–Time Implementation of an Adaptive Gain Equalizer for Speech Enhancement Purposes
نویسنده
چکیده
This paper presents a real time low-complexity implementation of 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-toNoise 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 be advantageous when implemented in real time since it offers low complexity, low delay and low distortion. Key-Words: Speech Enhancement, Speech Booster, Adaptive Gain Equalizer, Filter Bank, Digital Signal Processor

متن کاملImplementation Aspects of the Adaptive Gain Equalizer
The quality of speech, or important speech parameters such as the intelligibility, clearness or naturalness of speech, can be emphasized by signal processing. Such processing for improving speech quality can be found in telecommunication applications, e.g. mobile telephony, internet telephony or personal intercom. Blind methods are preferable over conventional because they do not require calibr...

متن کاملUtilizing Kernel Adaptive Filters for Speech Enhancement within the ALE Framework
Performance of the linear models, widely used within the framework of adaptive line enhancement (ALE), deteriorates dramatically in the presence of non-Gaussian noises. On the other hand, adaptive implementation of nonlinear models, e.g. the Volterra filters, suffers from the severe problems of large number of parameters and slow convergence. Nonetheless, kernel methods are emerging solutions t...
