- [Phase 37]: VAD ONNX assets served from ui/public/ same-origin to avoid COEP blocking CDN-served binary files
- [Phase 37]: useVadRecorder requests separate MediaStream ref for VoiceWaveform AnalyserNode — useMicVAD manages its own stream internally
- [Phase 37]: AudioContext not closed on cleanup in VoiceWaveform — reused across recording cycles to avoid repeated autoplay unlock prompts
- [Phase 37]: useVoiceMode hook created in plan 37-03 to unblock VoiceModeToggle during parallel execution
- [Phase 37]: Auto-play preference stored in localStorage (nexus:voice:autoplay), not nexus-settings — avoids server round-trip for fast UX

phase: 37-web-chat-voice-ui
plan: 03
subsystem: ui
tags: [react, voice, audio, shadcn, lucide-react, localStorage, tailwind]
# Dependency graph
requires:
- phase: 36-voice-pipeline-foundation
provides: POST /api/synthesize and POST /api/transcribe endpoints; voiceMode persisted via nexus-settings
- phase: 37-01
provides: COOP/COEP headers for SharedArrayBuffer; VAD ONNX assets
provides:
- ChatVoicePlayer: inline audio player with play/pause, auto-play, blob URL cleanup
- ChatVoiceBadge: Voice badge + SPOKEN/DETAILED parsing + collapsible full markdown
- VoiceModeToggle: three-pill Text/Voice In/Full Voice toggle with nexus-settings persistence
- useVoiceMode: hook for reading/writing voiceMode via PATCH /api/nexus/settings
affects: [37-04, ChatMessage integration, ChatInput integration]
# Tech tracking
tech-stack:
added: []
patterns:
- Blob URL lifecycle: createObjectURL on fetch response, revokeObjectURL in onEnded and cleanup
- SPOKEN/DETAILED regex parsing for dual-format voice responses
- Three-pill toggle pattern with active/inactive Tailwind classes + role="group" + aria-label
key-files:
created:
- ui/src/components/ChatVoicePlayer.tsx
- ui/src/components/ChatVoiceBadge.tsx
- ui/src/components/VoiceModeToggle.tsx
- ui/src/hooks/useVoiceMode.ts
modified: []
key-decisions:
- "useVoiceMode hook created in plan 37-03 (not 37-02) to unblock VoiceModeToggle — parallel execution"
- "ChatVoicePlayer fetches audio on text change, not on play — pre-loads audio for smoother UX"
- "Auto-play preference stored in localStorage (nexus:voice:autoplay), not nexus-settings — avoids server round-trip for fast UX"
patterns-established:
- "Pattern 1: blob URL cleanup — always revokeObjectURL in both onEnded and effect cleanup to prevent memory leaks"
- "Pattern 2: voice badge renders differently per messageType — voice_input shows badge+text only; voice_full adds player+collapsible"

# Phase 37 Plan 03: Voice Output Components Summary
**Inline audio player (ChatVoicePlayer), voice badge with collapsible markdown (ChatVoiceBadge), and three-pill mode toggle (VoiceModeToggle) — complete output-side voice UI**
## Performance
- **Duration:** 2 min
- **Started:** 2026-04-04T02:35:25Z
- **Completed:** 2026-04-04T02:37:21Z
- **Tasks:** 2
- **Files modified:** 4
## Accomplishments
- ChatVoicePlayer: POST /api/synthesize → blob URL → native `<audio>` element with play/pause controls, auto-play support on mount, and proper blob URL revocation on end/unmount
- ChatVoiceBadge: parses SPOKEN/DETAILED content format, renders Voice badge, spoken text, optional ChatVoicePlayer, and shadcn Collapsible for full markdown (voice_full only)
- VoiceModeToggle: three pill buttons (Text / Voice In / Full Voice) with active/inactive Tailwind styling, PATCH /api/nexus/settings persistence, auto-play checkbox in full_voice mode
## Task Commits
Each task was committed atomically:
1. **Task 1: Create ChatVoicePlayer and ChatVoiceBadge components** - `601508bf` (feat)
2. **Task 2: Create VoiceModeToggle three-pill component** - `562e4451` (feat)
**Plan metadata:** (docs commit — see final commit)
## Files Created/Modified
- `ui/src/components/ChatVoicePlayer.tsx` — Inline audio player: synthesize fetch, play/pause, blob URL lifecycle
- `ui/src/components/ChatVoiceBadge.tsx` — Voice badge + SPOKEN/DETAILED parsing + shadcn Collapsible for voice_full
- `ui/src/components/VoiceModeToggle.tsx` — Three-pill mode toggle with nexus-settings persistence and auto-play checkbox
- `ui/src/hooks/useVoiceMode.ts` — Hook: GET/PATCH /api/nexus/settings for voiceMode, loading state
## Decisions Made
- useVoiceMode hook created in this plan (37-03) to unblock VoiceModeToggle since plan 37-02 hadn't run in this worktree yet
- Auto-play preference kept in localStorage (not nexus-settings) for zero-latency reads on component mount
- ChatVoicePlayer pre-fetches audio on text prop change (not on user play click) for smoother playback experience
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Created useVoiceMode hook (plan 37-02 dependency)**
- **Found during:** Task 2 (VoiceModeToggle implementation)
- **Issue:** VoiceModeToggle imports useVoiceMode, but the hook was not yet present in this worktree (37-02 is a parallel execution)
- **Fix:** Created `ui/src/hooks/useVoiceMode.ts` implementing the exact interface specified in the plan context: `{ mode, setMode, isLoading }` using GET/PATCH /api/nexus/settings
- **Files modified:** `ui/src/hooks/useVoiceMode.ts` (created)
- **Verification:** VoiceModeToggle imports and uses hook; all acceptance criteria pass
- **Committed in:** `562e4451` (Task 2 commit)
---
**Total deviations:** 1 auto-fixed (1 blocking)
**Impact on plan:** Essential for correct parallel execution. Implementation matches plan-specified interface exactly.
## Issues Encountered
None — tasks executed cleanly once useVoiceMode was created.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- All three voice output components are complete
- ChatMessage needs to be updated to render `<ChatVoiceBadge>` for messageType voice_input/voice_full
- ChatInput needs VoiceModeToggle added to toolbar row
- These integrations are handled in plan 37-04 (ChatInput + ChatMessage integration)
