2.265 pip

Piper TTS is an Open Source neural-net TTS engine. This module exposes Piper TTS to Emacs.

  1. Sandbox for https://github.com/OHF-Voice/piper1-gpl
  2. Install piper-tts in a virtual environment whose bin directory is on Emacs’s PATH.
  3. Set location of voice data in pip-data-dir. Default is ~/.local/share/voices-piper
  4. Use that environment’s Python to run -m piper.download_voices. Download a voice with its --data-dir option set to pip-data-dir.
  5. M-x pip-speak to speak.
  6. At present piper is not suitable for use as a primary TTS engine for Emacsvox through this experimental per-request wrapper, given its model-load latency and fixed 22,050 Hz raw-output assumption.
  7. However it might be interesting to use it for lower-priority speech where quality trumps latency.
