 ## Supported Text to Speech tools
-Currently the only TTS system that is tested is [PiperTTS](https://github.com/rhasspy/piper).  As you need to run this program manually yourself you can use any other local systems.
+Have tested this with TTS systems [PiperTTS](https://github.com/rhasspy/piper) and [Chatterbox-TTS](https://github.com/resemble-ai/chatterbox).  As you need to run this program manually yourself you can use any other local systems.  Piper is pretty unintensive on resources, but chatterbox-TTS allows you to clone whatever voice you want, is generally much better quality and is generally my preferred TTS system for 2025.

       Currently TTS is expensive (cost of cloud or cpu time locally).  Converting a book with a large index, contents, appendix is a complete waste.  It's best to manually delete files you don't wnat to convert at this checkpoint.

 5. WAV -> MP3 via ffmpeg
    Currently Piper TTS only outputs wav files. The hardest part about converting these to mp3 is to inject the Title, Author, Chapter Title, and Cover into the ID4 tags of the MP3.
