I remember several years ago when I did a video shout out to all my peeps here at MC, a few of them said I sounded like Mister Rogers... that, I don't think so, lol... most of the time anymore, people tell me I sound exactly like my dad over the phone. Really, the best way I can describe my own voice is that I have similar problems with Steve like Jim did with Kermit: Steve is actually pretty close to my natural voice, that I have to be careful, because every once in a while, I'll slip out of the voice... so yeah, if you take Steve's voice, make it a little deeper, and remove that little comical texture from it, that's my voice.
Now then, can I just describe what my favorite person's voice sounds like? If you took Kristen Chenoweth's voice, and raised it an octave or two, that's what she sounds like, lol... if she ever gets mad (which I'm not sure she does), I'm willing to bet her voice probably reaches a level only dogs can hear.
