Vector quantization of speech

Started by abhisheksgumadi May 24, 2006
Hi,
I am working on low bit rate speech coding.
I have efficiently quantized the lpc coefficients using vector
quantization methods. I am looking at an efficient way of quantizing
the residue signal which is an important by product of the lpc analysis.
Can anyone suggest e a good method of quantizing the residue signals?

With Regards,
