Although I have no "voice" experience, my community acting and commercial experience spans many decades.
I was required to do a "Voice Over" for the TV series "Dead Zone"
I have acted in movies (Miracle, Ecstasy), Commercials (Frijj, Telenor, Aquassure), TV (Dead Zone, ACCESS TV - Alberta), Theatre (from Alan Ayckbourn, Beyond the Fringe, Mary Chase, Pantomimes, Kesselring).
BEd, Bristol University, England - Drama and Acting Teaching
MSC, Stirling University, Scotland - Public Relations
Studio On The Drive, Vancouver - Acting for TV & Commercials
Tom Todoroff - Acting
No professional studio, but I have a latest Mac computer and recording and editing software for basic production.
I consider myself a mimic. I pick up the cadence and presentation of a speaker and often find myself almost insulting them by unconsciously doing this.
In France recently I was complemented on my accent (even though my grammar was atrocious!)
