Terms of use

PiperHub is a directory of voices for Piper TTS, with synthesis demos right in the browser.

Voice licenses

Each voice belongs to its author and keeps its own license (shown on its page and repository). Check it before any use, especially commercial. When in doubt, ask the author.

Fair use

Synthesis runs entirely in your browser: entered texts never leave it. Use the site to listen, compare, and create, without harming authors or the service.

Warranties

Site provided as is, with no uptime or accuracy warranty. Models evolve; rendering may change between versions.

Effective October 5, 2026.
