vhdl speech recognition

Hey Guys, VHDL HELP

I am a beginner to VHDL. I know how to write basic codes in VHDL.
I want to implement a Speech Recognition system using FPGA. So i want to learn how to design the code in VHDL.
For that i have to learn the very basic of Signal Processing or Analyzing using small inputs.

Can anyone give me start to it? PLEASE

thanx in adv

speech recognition using vhdl

well, matlab has capabilities to work with HDL , in fact you can star to design filters, and then converting to vhdl code, these a list a software that i use:

xilinx ISE 9.2
matlab r2007a
system generator
acceldsp
active HDL 7.3
orcad 16.0

look for each one of them and learn how to use them , u can combine them to achive from basic to very complex aplications on vhdl, ... well.. c ya !

speech recognition vhdl

Thanx for the reply....it gave me a good starting point....

I have seen everyone talking about filters.
For out initial design we will use the
- DSP micro controller to process the incoming analog siganl. It will
filter and sample the signal to digital.
- Then the software stored in the uC will frame and window the
digitized the signal.
- This will then be passed on to the FPGA which will start comparing
the words using HMM.

Do i still have to implement the filters in FPGA? can i directly take the data from, lets say SRAM (where uC will store the processed digital signal) and use it compare?

That is how i have designed the system so far. Can anyone comment on this design, give some views....

thanx
