The NPM manifest declares MIT. The distributed phonemizer includes:
- Piper phonemizer, MIT, Copyright (c) 2023 Michael Hansen:
  https://github.com/wide-video/piper-phonemize
  https://github.com/rhasspy/piper-phonemize
- eSpeak NG, GPL-3.0:
  https://github.com/rhasspy/espeak-ng
  https://github.com/espeak-ng/espeak-ng

Full Piper MIT and eSpeak NG GPL-3.0 license texts accompany these notices.
No binary modifications are made. scripts/speech-assets.mjs copies the
package's piper_phonemize.wasm and piper_phonemize.data verbatim.
The upstream build uses Emscripten 3.1.47 and documents CMake flags, runtime
exports and the included eSpeak data; see the pinned build README above.
