This C++ TTS repo has moved out and left a note
A fast, local neural text-to-speech system that now points developers to its new home.

What it does
Piper is described as a fast, local neural text-to-speech system written in C++. At the moment, the repository contains nothing beyond a README announcing that development has moved to OHF-Voice/piper1-gpl.
The interesting bit
Neural TTS tooling tends to be Python-first, so a C++ project aimed at local synthesis is a notable outlier. It also accumulated 11,151 stars before its README was reduced to a single redirect line.
Key highlights
- Fast, local neural text-to-speech
- C++ implementation
- 11,151 GitHub stars
- README now redirects to
OHF-Voice/piper1-gpl - Tagged under speech-synthesis, text-to-speech, and TTS
Caveats
- No code, documentation, or build instructions remain in this repository.
- You must follow the redirect to find the current engine and its community.
Verdict
Developers looking for a local neural TTS engine should head to the new repository; if you are browsing for C++ source or release history here, you will find only a closed door.
