## Third-party notices

dsh-say ships no model weights, no voice data, and no third-party code. It
calls software the user installs separately. When you use those optional
backends, their own licenses apply:

- **GPT-SoVITS** — https://github.com/RVC-Boss/GPT-SoVITS — MIT License.
  If you publish a video or audio made with it, credit its authors.
- **Windows SAPI voices** — the built-in backend uses the speech voices already
  installed in your operating system. Those voices remain the property of their
  publishers; dsh-say only asks the OS to speak.
- **FFmpeg / ffplay** — https://ffmpeg.org — LGPL/GPL, used only as an external
  program for audio playback, never linked or bundled.

Voice models and reference audio you add are your responsibility: only use
material you have the right to use, and check the terms of whoever published a
model before redistributing anything produced with it.
