Closest to human TTS service I have tried and I wonder if it's possible to be even closer to almost undetectable? There is this bit that still sounded robotic.

Suggest having a low limit voice cloning for AppSumo buyers. It will serve as a trip wire purchase to buy their voice cloning service at a large discount. Possible?

Hope to have more Asian voices and conquer the bit on robotic voice and monotonous TTS.
