Keyboard Voice Activation

[ATIRacer]

Hello everyone. If this question has been asked before I apologize but I am new to teamspeak. I use teamspeak in a Nascar 2003 racing league. I currently have the voice activation set to a specified key on the keyboard. What I am trying to do is on my steering wheel for the game I have several buttons. I would like to map one of the buttons to my steering wheel to Teamspeak as the voice activation button so when I am racing I can just hit that button and talk without taking my hand off of the wheel.

has anyone done anything like this or know how to map the button to emulate the keystroke??

Thanks
