If I have an accent (unsure?) then Alaskan. But, I am of European origin and do have a marked continental accent too. I have a very feminine sounding voice - wish I had a stronger voice though. In some ways, although Dr. Grandin does sound a bit awkward, she does have a commanding tone. When I fairly recently gave a verbal presentation, I had a communications professor listen in - he said it was well done! I am flattered, but it does sound.....different? Maybe stilted some, like a recording. I have been a TA for chemistry lab session; I guess my students do notice?
But, like others note, Autistic sounding speech isn't that remarkably odd. Of course, some accents are more 'off' sounding than Autistic speech. Oh, an Alaskan accent sounds very enunciated. Hate to admit this, but I might sound a bit like Sarah Palin. I am from the same hometown as Sarah. I'm not native Alaskan and any Eskimo languages are tough for any European/American to emulate.
I've heard Aspie speech that sounds awkward in ways that are hard to identify.
sidenote: Akutaq ice cream.......acquired taste? I don't personally partake, but it's salty/sweet (and kind-of yucky).
