I have been told that I have a sexy voice by my wife of course, but others find it soothing when I'm engaged in regular conversation. If I'm to be expected to "Do" a voice, as in telling jokes or a narrative, I'm adept in faking English speaking accents including Cockney, Aussie, and I make a prety good HillBilly sometimes too.
In circumstances where verbatim reading is required, I can adeptly differentiate between characters with intonation, volume, or assumable physical characteristics.
I've done plenty of stage presentations at large functions (awards shows, trophy presentations, and charity banquets)and have been known to engage a crowd with spritely banter relative to the event. I've even done a couple of impromptu auctions for fund raisers.
As "celebrant" I have comforted crowds at final celebrations of life with solemnity and realism.
