third_party

Vendored dependencies. Everything the tool needs to run is kept here so the project does not depend on external downloads that can disappear. Only toolchain packages (Wine, Winelib, ffmpeg, python3, unshield, mingw) are installed by the system.

speech.h

speech.h — Microsoft Speech API 4.0 SDK header. Used by host/sapi4host.c. Copied from the public SAPI4 header published in the community gist referenced by the asset repository (see docs/NOTES.md).

sapi4/

The SAPI4 runtime and the MSTTS (Sam/Mary/Mike) voices, extracted from the original Microsoft installers. Private archival copies; do not redistribute.

• spchapi/SPEECH.DLL, spchapi/SPCHAPI.INF — SAPI4 runtime and its registration INF.
• msttsl/msttssyn.dll, msttsl/*.vce, msttsl/*.cfg, msttsl/mstts.inf — MSTTS engine, voice data and registration.
• installers/spchapi.exe, installers/msttsl.exe — original installers, kept for completeness (the extracted files above are what setup-prefix.sh uses).

flextalk/

• data1.cab — InstallShield cabinet with the AT&T Flextalk 2.1 engine and the "Keith Bell" / "Kerry Watson" voices (the archive.org package). setup/install.sh extracts it with unshield -O into flextalk/extracted/ (gitignored).

nettts-reference/

• vox_parser.cpp, vox_parser.hpp — the VOX prosody encoder from h4rm0n1c/NetTTS, kept as the reference for validating setup/vox_parser.py. Upstream declares no license; these files are reference-only and are not linked into anything we ship.

• nettts_flextalk_vox_profile.reg — NetTTS's approximated Valve VOX speaker profile for Keith Bell (the source of the vox/hev presets in setup/veskslop-tts.sh).
