FPGA speech recongintion system

[shimon001]

Hi, I m currently working on speech recognition system using the FPG
technology.

At first I have to implement audio recording system which will store th
audio data into memmory and when the start of speech will be detecte
(comparing the energy of audio signal, or zero corossing) the system wil
start to compute the features of audio signal (cepstral coiefficients).

I would really need some help with this audio recording system and wit
recognizing the start of the speech.

I have read some material about this stuff but I thing I need some hel
with first steps of my design.

Don't hesitate to ask any further questions. (I am almost sure I haven'
give enough information...)
Thanks in advance.

Hi,
doing some audio recording is not so complicated.
Just grabbing some samples and putting them into some RAM.

First question that arises:
Do you already have some hardware that you are going to work with?
What shall be the source for your audio signals? Some microphone on an
ADC, or some sort of digital interface?

Once your hardware is defined, you can design the interface part.

And what shall happen, when you finally got some data in the RAM? How
will you check the successful recording?

Have a nice synthesis

I hope your FPGA has lots of DSP resources on it!
