You need to get a web camera first and a UStream account:
USTREAM, You're On. Free LIVE VIDEO Streaming, Online Broadcasts. Create webcasts, live stream videos on the Internet. Live streaming videos, TV shows
But that won't do it . . .
You need to find someone close to you with a radio and a UStream account and a web camera.
But that STILL won't do it . . . not without a loss of quality anyway . . .
To monitor your own sound is to use another radio for receiving (preferably something that has a wide receive - and then turn the RF Gain too), hook up some headphones to it, turn the power on the transmitting radio WAY DOWN (1 - 1/2 watt output) and then you will get a fair idea of what you sound like.
