No. No. It is not Vic Perrin. It doesn't sound a thing like Vic Perrin, and I have no idea how that myth got started.
I'll check this when I get home tonight, but I believe this idea may have originated in Allan Asherman's excellent Star Trek Compendium
, in which Asherman speculates that the "Menagerie" version of the Keeper might have been voiced by Vic Perrin. As I said, I'm not entirely certain of this - I'll check my copy of the Compendium
when I get home tonight.
