AI's Progress Cont'd

I've been keeping up with the progress of AI and text-to-speech technology since the beginning, at least what we're shown anyway. From what I know, it's gone from the comical voice of the Speak 'n' Spell, that sounded like a drunk robot doing all it could do not to hurl, to the B-movie robotic voice of Stephen Hawking, to where it is today, almost human-sounding. 

 It still occasionally doesn't understand the context of how a word is used in a sentence, so it doesn't use the proper inflection or know whether or not to accent a word or syllable. The journey from Speak 'n' Spell to today has been interesting and amusing. 

 You can listen to the narration of a video and think it's a human for a good while, but then you'll catch mistakes. I think it's just what we're shown, and that AI is already sentient and can speak perfectly, but that's another story.

 I was watching a vid about drummer Steven Adler getting canned from GNR. I figured the narrator's voice was AI, and sure enough it made a boner. It pronounced a sentence like this: "Guns AND Roses played at the Whisky A Go-GO." Oh-kay. It would seem that AI still has some work to do...or does it?
