I think you may have missed what I was getting at. There's 6 American Male voices that come with macOS; Alex and Tom both sound the best with Alex being the default Mac voice everyone recognizes. However you can also get other accents for English; Australian, Indian, Irish, Scottish, South African and British (Daniel, Oliver). What I'm looking for is Southern American; the kind of accent you find in the deep south. I did find one company (Cepstral) that makes a text-to-speech with that accent (he's called Dallas) but it costs $45 and for the price is very robotic.
