Basically you can not do voice recognition on an Arduino.
What you can do is to add another processor to do it on a shield.

However it is not very good at recognition but it satisfies some people.

what is the code

It depends on the the circuit.

Generally we don't write code for you here but we can help you learn to write code yourself.
