Hi
      This is vijaya bhaskar vasha ,i am doing my M.Tech project on secure speech communication
on TMS320C6713 DSP microprocessor i.e. first i need to compress the speech signal and then
encrypt it. compression algorithm i  choose is  CELP .
But the problem is now that i am not getting the exact block diagram of the CELP.
           So if some has related material to this please  send to me  to this email id.If 
some body is doing on same domain and on related projects related to this topic please respond

thanks&
regards.

Hi Vijaya,

I would like to suggest you to buy or borrow a book on speech coding, Such as "Speech
Coding Algorithms : Foundation and Evolution of Standardized Coders" by Wai C. Chu. You
will find the block diagram in it.

Best,
Mingyu
