edge-tts
Use Microsoft Edge's online text-to-speech service from Python WITHOUT needing Microsoft Edge or Windows or an API key
Project mention: Show HN: Voice Cloning and Multilingual TTS in One Click (Windows) | news.ycombinator.com | 2025-01-26There is a MIT license in the repo. In that sense it's open source.
It's using "Edge TTS", which I believe means use API keys stolen [1] from Microsoft Edge and hope Microsoft doesn't sue you, non jolly-roger flying internet users beware.
Can't speak to other models and their licenses, I stopped looking after I saw this since I don't feel the need to use this.

Kokoro-FastAPI
Dockerized FastAPI wrapper for Kokoro-82M text-to-speech model w/CPU ONNX and NVIDIA GPU PyTorch support, handling, and auto-stitching
Project mention: Microsoft VibeVoice: A Frontier Open-Source Text-to-Speech Model | news.ycombinator.com | 2025-09-03I'm using Kokoro via https://github.com/remsky/Kokoro-FastAPI. It has a `generate_audio_from_phonemes()` endpoint that I'm sure maps to the Kokoro library if you want to use it directly.
My usage is for Chinese, but the phonemes it generated looked very much like IPA.

Project mention: Abogen – Generate audiobooks from EPUBs, PDFs and text | news.ycombinator.com | 2025-08-09
It's probably due to the unusual sound format, 24kHz PCM, and the fact that it was somehow forced into a WebM container, which only supports the Vorbis and Opus formats.
It looks like they created it using the "higher quality" ffmpeg command line, except for the "webm" final extension, producing the opposite of what's described as "an MP4 file that's compatible with more devices".
