verified audible (0/59/100 produce different waveforms at equal duration). Changing
them requires a registry edit and re-selecting the voice.
## VOX parser
- `setup/vox_parser.py` reimplements the NetTTS VOX prosody encoder (vendor tags
`\!wH1/\!wH0`, `\!br`, `\!sfNN`); the host already passes `TTSDATAFLAG_TAGGED`, so
the engine honors them.
- Validation: the reference `vox_parser.cpp` from a local clone of
`h4rm0n1c/NetTTS` was compiled with g++ in a throwaway harness and diffed against
the Python port; outputs are identical on the 31-line corpus. Re-check after any
parser change while the clone is available.
- VOX mode is Flextalk-only. The wrapper enables it with `VESKSLOP_TTS_VOX=1`
(`VESKSLOP_TTS_VOX_CLEAN=1` drops the stutter wrapper) and it takes precedence
over `VESKSLOP_TTS_WORDS`.
