Some of the Amazon Text To Speech samples:Yeah they sound good except Kendra. I wonder how they'd feel with longer samples though. Like after a minute, it'd be really easy to notice all the repetition and mistakes.

Pretty neat. Some of them sound pretty good, but there's still room for improvement. Especially on Kendra...
