Round 2 from live testing:
- Clipping root cause: the endpointer committed on any 1.1s pause, so a
thinking pause after a sentence opener sent one word; a speculative
Whisper pass over that fragment then stalled the real commit ~3.5s on
the Jetson. Young utterances now hold a 1.8s endpoint until 1.2s of
speech accrues, speculative decode waits for 700ms of speech, resume
is unconditional after any 650ms gap (server-frozen snapshots can
never reach commit), and the noise floor is capped so playback echo
cannot deafen onset. Deterministic capture-continuity probe added.
- Stitching now fires for any barge-cancelled send within 20s,
regardless of partial assistant output.
- The workspace-drawer dark rectangle was our own HUX chrome resolving
undefined theme tokens (--bg-primary) to a flat box; bootstrap.css
bridges the real theme tokens and drops a compositor-hazard
backdrop-filter.
- Conversation mode: full-viewport hands-free overlay with an energy-
driven orb (mic RMS in, TTS activity out), state caption, live
transcript/reply captions, mute and exit controls, focus trap,
Escape, reduced-motion support. Voice lane 253 tests green.

Three conversational fixes for hands-free chat:
- The microphone now stays hot for the whole session: capture runs on
its own epoch, re-arms immediately after each utterance endpoints,
and keeps recording through transcribing/thinking/speaking - speech
is never lost to Hermes being busy. Speech onset during a response
cancels it through the live capture path (echo-guarded exactly like
the old monitor) without touching the running recorder.
- When the user talks over Hermes before any visible reply appeared,
the interrupted utterance and the follow-up are stitched into one
message (20s window), so the response addresses the whole thought.
- TTS speaks 15% faster by default (server-side length_scale, no pitch
shift), user-tunable via hermes-voice-tts-speed (0.5-2.0), honored on
streaming, WAV fallback and thinking-cue paths.
245 voice-lane tests pass; single getUserMedia site preserved;
Dockerfile grep guards verified.

Port the original #27 detected-language pipeline onto the verified PR #39 prerequisite while preserving the current-main conversation instrument and host continuity changes.
Keep voice selection server-side with no user selector or client voice field. Reuse 207c16ab only for its stricter exact-code trust boundary, omitting malformed or absent language so Piper defaults to Amy.
Supersede draft PR #26 with a merge-safe prerequisite: bake and preload the amy, irina, and claude Piper models, route only validated server-side language to fixed voices, and leave the live voice deployment manifest unchanged.
Remove the pinned WebUI speaker selector and its persisted preference, omit client voice fields from every outbound TTS path, and keep hands-free Voice Mode and the conversation instrument intact. Hostile or legacy voice fields remain ignored by the Piper server.
