Voice detection library
I need a library that detect start and end of speaking of human, I do not require it to detect what the peoples say or who say that I just need to detect if any one speaking or not.
the most important thing for me is speed, I need this library to be very fast because I have almost 100 source of voice that I should do some action on them in a nearly real time application and libraries that do voice recognition or detect identity of speaker can't handle this huge amount of data in real time.

I have no experience in this field so please give detailed information .
