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.

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.
