I use "kokoro-tts" CLI, which has better chunking/splitting. https://github.com/nazdridoy/kokoro-tts It generates a directory of audio files, along with a metadata file for ebook chapters You have to use m4b-tool to stitch the audio files together into an audiobook and include the chapter metadata, but it works great: https://github.com/sandreas/m4b-tool I've been meaning to write a post on this workflow because it's incredibly useful
