Speech enhancement using wavelet packets
A new speech enhancement algorithm for speech corrupted by background noise based on Wiener filtering and discrete wavelet transform was developed. Wavelet Packet Analysis Tool of MATLAB was first used to break down the noisy speech into different sub-band components. Next, the sub-band components o...
