+### Half-Life VOX / HEV presets
+
+The Half-Life announcement voice (VOX / Black Mesa Announcement System) is the Flextalk
+engine's **Keith Bell** voice with an adjusted speaker profile. NetTTS publishes an
+approximation of Valve's settings (`scripts/winetricks/nettts_flextalk_vox_profile.reg`,
+see its issues #53/#54/#67): the profile targets Keith Bell's speaker key and leaves
+Kerry Watson at factory values. The wrapper implements it as a preset:
+
+    VESKSLOP_TTS_PRESET=vox   # implies VOX prosody unless VESKSLOP_TTS_VOX is set
+    VESKSLOP_TTS_PRESET=hev   # HEV suit starting point (see note below)
+
+| Profile value | Factory (Keith) | VOX preset | HEV preset (approx.) |
+| --- | --- | --- | --- |
+| Pitch | 27 | 3 | 15 |
+| Speaking Rate | 33 | 17 | 24 |
+| Prominences | 17 | 22 | 22 |
+| Head Size | 46 | 52 | 52 |
+| Lowering | 40 | 40 | 40 |
+| Volume | 100 | 70 | 70 |
+| Expression | 59 | 59 | 59 |
+
+- Presets apply only to `keith-bell`; every other voice keeps its defaults.
+- Precedence: preset < `VESKSLOP_TTS_PROFILE` < `VESKSLOP_TTS_EXPRESSION`.
+- Equivalent explicit override:
+  `VESKSLOP_TTS_PROFILE='pitch:3,rate:17,volume:70,prominences:22,head_size:52,lowering:40'`.
+- The NetTTS profile also sets `Gender`, `Line Mode`, and a set of text-class DWORDs
+  (address/date/money classes, abbreviation expansion, and so on). Those affect text
+  normalization rather than the audible voice, so the wrapper does not write them.
+- HEV suit: Half-Life 1 credits the suit sounds to Kelly Bailey; no settings were ever
+  published. The `hev` preset is a starting point (less extreme than VOX); tune pitch and
+  rate to taste. VOX prosody is optional there (`VESKSLOP_TTS_VOX=1`).
+- Measured with the wrapper on the same line: VOX preset 5.83 s, HEV 3.79 s, factory
+  3.35 s (the VOX preset is slower and gains the VOX cadence).

 ### Inline rate/pitch controls (engine-side)
