Hi Isamar,
There is a trial project underway for Asterisk and www.tellme.com but
this is a commercial implementation of Speech Recognition using external
resources and infrastructure.
This will not be free.
Let me know if you have a commercial application that has funding behind
it.
Regards,
Interactive Intelligence has a commercial Speech recognition API for
this purpose.
