Hey guys, for the record, in our description we used "Standard American accent" as a bit of a catch-all term, not quite in the most technical manner.
One of our dialect coaches, Ron Carlos, slacked me the following blurb: The accent taught in American theater schools (which we're calling SAE here, most would call it Mid-Atlantic) is an accent that was popular in Hollywood in the 40s. Many schools have modified it to sound more modern. And we definitely don’t use that accent in BoldVoice. Ours is more modern: for example, can’t and Cod will have two separate vowel sounds, and Tune and toon will sound the same.
Okay, that's helpful, thanks for going right to the source - yes, that's what I learned in theater school (referred to as SAE), and found that it was useless for everything except Shakespeare and poetry. I thought it pretty unlikely that was what you were going to teach non-native english speakers.
I'm guessing that the meaning of "General American English" has drifted over the years - it seems like Speak With Distinction is from 1942, when those sorts of pronunciations were common, and it would have been appropriate to teach that to non-native speakers. Now the accent is a little bit different, just like how "business casual" now includes certain types of jeans.

not my area of expertise, but I had assumed from the article that SAE and GAE are equivalent, but maybe not?
