If you haven’t had much (or any) coaching, let me help you with the thing I hear most.

I’d estimate that at least 90% of the time, the first time I listen to someone, I hear a layer of superficiality.  (Oddly enough, it’s even worse with team shows.)  Something real-ish, but not quite real.  A “smiley” sound in the voice, elongated “mock” differences of opinion (in a team show), a delivery that isn’t intimate or personal, extended setups to get into something – it’s almost always there, holding back that talent from sounding like they’re actually talking to me.  Some suggestions:

1. Use real words – words that real people use in everyday conversations.
2. Develop your mic technique, so you can speak in a normal tone of voice.
3. Don’t get too officious with your language.
4. RELAX and “let off the gas.”  I’m only a couple of feet away in the car.  LOUD is annoying, unless it’s a genuine moment.

If you ever had anyone ask you to “Say something in your radio voice,” the answer should be, “I don’t have one.  I just talk.”
