Voice command recognition.

[Sachin]

Hello everyone,

 

Am right now working on signal processing am using DSK6713 board in my college. It is not only complicated but also very costly to use that board in real time applications. I was hoping if the same is possible in a basic 8051 controller without ussing any external devices like sound matching circuis and all.

 

I know its not meant for signal processing but I thought of implementing in the following way, which am not very sure to work..

 

I wil be using an ACD to convert the voice signals into digital and stose some commads in the controller. Later wil program it to match the real time inputs with all the pre recorded data and execute the one which matches the best. I will set a lower limit like some minimum number of bits to be matched to carry out the instruction else it wil go on executing instrultions which are the best match for even random noise.

 

I wil implement signal transforms (If needed)  in C language as done in Code Composr Studio.

 

Any help on this will be really helpful

Well the overall idea sounds good, but seems difficult to acheive accuracy to acheive using 8051.

How else can I implement it.. 

 

I saw similar projects using Atmega 16. Any idea on how to do that??
