Multiband excitation vocoder implementation in MATLAB

SPEECH PROCESSING PROJECT REQUIRED INCLUDES MATLAB CODE FOR [url removed, login to view] FINAL YEAR:

Multiband excitation speech coder/Multiband excitation vocoder implementation in MATLAB:

The speech signal is segmented in frames using a hamming window and for each frame the parameters are calculated.

Encoder : speech is analysed and two parameters:

1. spectral envelope

2. excitation envelope (i.e pulse train for voiced and noise for unvoiced)

product of these parameters is called synthesised spectrum

Decoder : for voiced samples the envelope samples and fundamental freq. passed through a bank of harmonic oscillator and voiced speech is obtained

unvoiced speech weighted overlap add method used.

the voiced and unvoiced speech are then added to obtain the synthesised speech
