Speech Enhancement using an Adaptive Gain Equalizer
Blekinge Institute of Technology, Department of Telecommunications and Signal Processing2003 (English)Conference paper (Refereed) Published
This paper presents a noise reduction method forspeech 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 be advantageous since it offers low complexity, low delay and low distortion. Also, there is no need for a Voice Activity Detector (VAD). The method is stand-alone and works regardless of speech coding schemes and other surrounding adaptive systems.
