Anyone who has used a GPS voice that mangled a street name knows the pleasure of a text to speech engine that does not sound like a hostage video, and Piper is the small one people reach for. The README calls it a fast and local neural text-to-speech engine that embeds espeak-ng for phonemization, you install it with pip, and it offers a Python and C/C++ API, a web server and Docker files.

Piper scores a 5 on footprint, a 4 on lock-in, self-direction, power and delivery and a 3 on longevity.

The code is GPL-3.0 and lives with the Open Home Foundation, whose README says it is looking for maintainers for Piper, so Longevity is a 3. The page lists no platforms, no languages and no price, and it links to a separate voices document, so check that your language has a voice before you plan around it. It is a tool for people who are comfortable with Python or a command line, and not an app with a window.

    What stands out

  • Turns text into speech on your own computer with one pip install
  • GPL-3.0, and the Open Home Foundation is looking for maintainers
  • Built for developers, with no window to click in
