Well Microchip has a voice recognition library/API, for $2,600. There are some voice recognition chips out there, but they are for experienced designers, not beginners.

My advice is to see if Microsoft's Speech API is available for WinCE .NET, I think it is. Then do it on a WinCE device.
 

calculator operated by my voice

the dsp i use , it has its own library of 100 words for speech recognition, +-*/ not in it. i can not modify it also. the only way i can do is in the software of my pic. the only idea i can come out is as below
step 1 user choose "1=+ 2=- 3=* 4=/"
step 2 user "say the 1st number"
step 3user "say the 2nd number"
step 4 "answer"
i will be using pic18f452.
