Real-Time Implementation of an Adaptive Gain Equalizer for Speech Enhancement Purposes
Blekinge Institute of Technology, Department of Telecommunications and Signal Processing2003 (English)Conference paper (Refereed) Published
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 timeS ignal-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 when implemented in real time since it offers low complexity, low delay and low distortion.
