I've tried one that works surprisingly well. Each sentence had great pacing, cadence, and correct enunciation- even had tone right when someone was shouting or angry or sad.

I wouldn't really recommend it, though. While I couldn't pick any single thing out that was wrong, overall it just didn't quite flow. It's like watching someone try to act that is technically doing everything right, but it just isn't good. It basically didn't understand the greater context of the story and was saying lines.

It was uncanny valley, but exclusively with voice.

I thought people mainly paid for the large library

Is there an offline tool that generates realistic audio for epubs as Mp3 ? Something like the free Ai tool, Vibe which is for transcription. Is there something similar for TTS, runs locally without complicated setup ( most are complicated using python and etc just for installation)

edit: needs to be close to realistic or at least accurate pronunciation because I am using the audio from books to learn languages. To improve listening comprehension while reading book.
