Same here. Not only the result is the best so far and instantly useable, the website is great to use and the fastest.
The voices do lose a bit of character and accent, though. On the other hand that makes my own voice much more useable. That's probably for the better, and good for video narration, audiobooks and marketing.
But I'm curious about the Video Game offering [1], where it says "You control the enunciation and emotion; the pitch and prosody; rate, duration, and contour". Is that planned for the future?
