  stackvox downloads the ONNX-converted model (`kokoro-v1.0.onnx`) and voice
  pack (`voices-v1.0.bin`) from the kokoro-onnx GitHub release assets on
  first use and caches them under `~/.cache/stackvox/`. These files are
  neither modified nor redistributed by stackvox.

phonemizer-fork
  Licensed under the GNU General Public License v3.0

  phonemizer-fork is a transitive runtime dependency of kokoro-onnx. It is
  installed by pip alongside stackvox but is neither modified, bundled, nor
  statically linked into stackvox itself — stackvox and phonemizer-fork
  communicate only through phonemizer-fork's published Python interface at
  runtime. Downstream users who distribute a combined work that includes
  phonemizer-fork should review GPL-3.0 obligations for their own
  distribution.
