And why do you need a FPGA for that task? What kind of "manipulation" do you have to do on the phone line? For voice recognition you can simply connect a sound card to the telephone and implement a decoding stage.
thanks for your reponse, my problem is to decode eight (08) line phone and then save it in may pc spmultanely .if it's possible with sound card haow i can implement a decoding stage.thank's a lot
This is actually something digital telephony has been invented for. There are special interface cards for PCs allowing you to process between 2 and 30 voice channels per card. Alternatively you can use VoIP and software like Asterisk. It has a feature which allows custom voice response systems.
thanks , and how u use asterisk and voice over ip to implement py project ,
Ask the supervisor appointed to your project.
