+
+# Requirements: Nexus v1.6 — Voice Pipeline + Minimal Message Bridge
+
+**Defined:** 2026-04-04
+**Core Value:** A fresh onboard asks for ONE thing (root directory), auto-creates PM + Engineer agents, and drops you in the dashboard.
+
+## v1.6 Requirements
+
+### Voice Pipeline
+
+- [x] **VPIPE-01**: User's voice input is transcribed via local Whisper STT with automatic language detection
+- [x] **VPIPE-02**: Agent text responses are synthesized to speech via local Piper TTS in under 3 seconds
+- [x] **VPIPE-03**: Voice pipeline accepts audio from any transport (web chat, Telegram) via a shared VoicePipelineService
+- [x] **VPIPE-04**: Audio from any source is transcoded to WAV 16kHz mono via ffmpeg before Whisper processing
+- [x] **VPIPE-05**: Voice mode flag on messages triggers voice-optimized response formatting (no markdown, natural prose)
+- [x] **VPIPE-06**: Every voice interaction produces dual output: spoken prose response + full text with code blocks
+- [x] **VPIPE-07**: TTS plays first sentence while subsequent sentences are still synthesizing (sentence-buffered streaming)
+- [x] **VPIPE-08**: User can synthesize a single text response into multiple language audio outputs (multi-language TTS)
+
+### Web Chat Voice
+
+- [x] **WCHAT-01**: Mic button in chat input starts/stops voice recording with visual state (idle/recording/processing)
+- [x] **WCHAT-02**: Recording auto-stops on silence detection via VAD (voice activity detection)
+- [x] **WCHAT-03**: Real-time waveform/amplitude visualization displays while recording
+- [x] **WCHAT-04**: Voice response audio plays inline in chat message with audio player controls
+- [x] **WCHAT-05**: User can toggle voice mode: text only / voice input only / full voice (input + output)
+- [x] **WCHAT-06**: Auto-play of voice responses is configurable (on/off in settings)
+
+### Telegram Bridge
+
+- [x] **TGRAM-01**: Single Telegram bot relays text messages bidirectionally between user and agents
+- [x] **TGRAM-02**: Agent replies in Telegram are prefixed with agent identity (e.g. `[PM]`, `[Engineer]`)
+- [x] **TGRAM-03**: Telegram voice messages are transcribed (OGG → Whisper) and forwarded to agent as text
+- [x] **TGRAM-04**: Agent responses can be sent back as Telegram voice notes (TTS → OGG)
+- [x] **TGRAM-05**: Telegram bridge uses long polling (no public HTTPS required)
+- [x] **TGRAM-06**: Telegram bridge is under 500 lines of code
+
+### Onboarding
+
+- [x] **ONBRD-01**: Onboarding hardware probe detects Whisper STT and Piper TTS capability
+- [x] **ONBRD-02**: Onboarding presents voice enable/skip step based on hardware detection results
+- [x] **ONBRD-03**: Guided BotFather setup flow for Telegram bot token during onboarding
+
+## Future Requirements
+
+### Voice Enhancements
+
+- **VFUT-01**: Wake word detection ("Hey Nexus") for hands-free activation
+- **VFUT-02**: Real-time speech-to-speech streaming (full-duplex WebSocket)
+- **VFUT-03**: Streaming TTS word-by-word playback
+
+### Telegram Enhancements
+
+- **TFUT-01**: Deep Telegram ↔ web chat session sync via Postgres event bus
+- **TFUT-02**: Rich Telegram elements (inline keyboards, threaded replies)
+- **TFUT-03**: Per-agent Telegram bots
+
+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| Real-time speech-to-speech | Entirely different architecture (LiveKit/Pipecat); future milestone |
+| Per-agent Telegram bots | Maintenance nightmare; single bot + agent prefix is correct |
+| Deep Telegram ↔ web chat sync | Requires Postgres event bus; deferred to v2.2 Command Center |
+| Telegram inline keyboards/threads | Thin bridge only; rich elements deferred to Command Center |
+| Wake word detection | Always-on mic; hardware device concern; future |
+| Streaming TTS word-by-word | Audio clicks/gaps; sentence-buffered gives 95% of the benefit |
+| Inline code execution over Telegram | Security risk; bridge is relay only |
+| GSD formatting in Telegram | Stateful session tracking; plain text + Markdown v1 only |
+| Transcription editing before sending | Breaks hands-free flow; show transcript in chat bubble after |

+### 🚧 v1.6 Voice Pipeline + Minimal Message Bridge (In Progress)
+
+**Milestone Goal:** Transport-agnostic voice pipeline (Whisper STT + Piper TTS) integrated into web chat, plus a minimal Telegram bridge for phone access. Voice infrastructure designed to survive v2.2 Command Center migration.
+
+## Phases
+
+- [x] **Phase 36: Voice Pipeline Foundation** — Transport-agnostic VoicePipelineService (transcribe, synthesize, formatForVoice), voice.ts route, ffmpeg audio transcoding, voiceMode flag, dual output pattern (completed 2026-04-04)
+- [x] **Phase 37: Web Chat Voice UI** — VAD silence detection, waveform visualization, voice mode toggle, inline audio player, auto-play toggle, COOP/COEP headers (completed 2026-04-04)
+- [x] **Phase 38: Telegram Bridge** — grammY long polling relay, text + voice note bidirectional relay, agent identity prefix, BotFather onboarding setup (completed 2026-04-04)
+- [x] **Phase 39: Voice Polish** — Sentence-buffered TTS streaming, multi-language TTS output, onboarding STT/TTS hardware detection step (completed 2026-04-04)
+
+## Phase Details
+
+### Phase 36: Voice Pipeline Foundation
+**Goal**: The transport-agnostic voice pipeline is live and callable from any consumer — web chat, Telegram, or future integrations — with correct audio transcoding, voice mode flag propagation, and dual output formatting baked in from the start
+**Depends on**: Phase 35 (v1.5 shipped)
+**Requirements**: VPIPE-01, VPIPE-02, VPIPE-03, VPIPE-04, VPIPE-05, VPIPE-06
+**Success Criteria** (what must be TRUE):
+ 1. Posting a WAV audio file to `POST /api/transcribe` returns a transcription with detected language, regardless of whether the request came from the web UI or a test harness
+ 2. Calling `POST /api/synthesize` with a markdown-heavy agent response returns two outputs: a voice-optimized prose version (no markdown) and the original full text with code blocks
+ 3. A WebM/Opus browser recording and an OGG/Opus Telegram voice note both produce identical Whisper transcription quality after ffmpeg transcodes each to WAV 16kHz mono
+ 4. The `voiceMode` flag on a chat message survives from client request through Express route to message persistence — verifiable in the DB record
+ 5. `nexus-settings.json` accepts `voiceMode: "text" | "voice_input" | "full_voice"` and `telegramToken` fields without breaking existing settings reads
+**Plans**: 3 plans
+
+Plans:
+- [x] 36-01-PLAN.md — VoicePipelineService: ffmpeg transcoding, Whisper STT, Piper TTS, formatForVoice
+- [x] 36-02-PLAN.md — Schema extensions: voiceMode in shared validators/types + nexus-settings
+- [ ] 36-03-PLAN.md — Voice routes, chat.ts voiceMode wiring, app.ts mount, old transcribe removal
+
+### Phase 37: Web Chat Voice UI
+**Goal**: Users can speak to any agent in web chat — recording auto-stops on silence, a live waveform confirms the mic is active, responses play back automatically (toggleable), and voice mode is a first-class setting
+**Depends on**: Phase 36
+**Requirements**: WCHAT-01, WCHAT-02, WCHAT-03, WCHAT-04, WCHAT-05, WCHAT-06
+**Success Criteria** (what must be TRUE):
+ 1. Clicking the mic button starts recording; the waveform animates to show audio levels; speaking and then pausing for 1.5 seconds auto-submits the recording without pressing any button
+ 2. The voice mode toggle has three visible states (text only / voice input / full voice) and persists the selected mode across page refreshes
+ 3. An agent response delivered in full voice mode plays back automatically in the chat thread; the auto-play can be turned off in settings and stays off after a page reload
+ 4. The chat message for a voice interaction shows a voice badge and an expandable section revealing the full markdown response with code blocks intact
+ 5. Voice recording and VAD work correctly in Chrome and Firefox on the Mac Mini (COOP/COEP headers satisfy SharedArrayBuffer requirements)
+**Plans**: TBD
+**UI hint**: yes
+
+### Phase 38: Telegram Bridge
+**Goal**: The user can message any Nexus agent from their phone via Telegram — text and voice notes both work, agent identity is visible on every reply, and the bot is set up through guided onboarding with no manual token entry in config files
+**Depends on**: Phase 36
+**Requirements**: TGRAM-01, TGRAM-02, TGRAM-03, TGRAM-04, TGRAM-05, TGRAM-06, ONBRD-03
+**Success Criteria** (what must be TRUE):
+ 1. Sending a text message to the Nexus Telegram bot from a phone produces an agent reply prefixed with the agent name (e.g. `[PM]: response`) within 10 seconds
+ 2. Sending a voice note to the Telegram bot produces a transcription confirmation message followed by the agent's text reply — the bot does not silently fail or miss the update
+ 3. Requesting a voice reply from the bot returns an OGG voice note that plays back correctly in the Telegram mobile app
+ 4. The Telegram bridge runs via long polling with no public HTTPS endpoint required — verified by running on the Mac Mini behind NAT
+ 5. The entire `telegram.ts` service file is under 500 lines
+ 6. The onboarding wizard includes a BotFather setup step that walks through creating a bot token and saves it to `nexus-settings.json` without manual file editing
+**Plans**: TBD
+
+### Phase 39: Voice Polish
+**Goal**: Voice responses begin playing before synthesis is complete (sentence-buffered), a single response can be synthesized in multiple languages simultaneously, and new installs can detect STT/TTS hardware capability during onboarding and enable voice in one step
+**Depends on**: Phase 37
+**Requirements**: VPIPE-07, VPIPE-08, ONBRD-01, ONBRD-02
+**Success Criteria** (what must be TRUE):
+ 1. For a multi-sentence agent response, the first sentence begins playing in the browser before the second sentence has finished synthesizing — the gap between text completion and first audio is under 1 second
+ 2. A user can request the same agent response as audio in both English and Danish; both OGG files are generated and available for playback without a second agent call
+ 3. On a fresh install, the onboarding hardware probe reports whether Whisper STT and Piper TTS are runnable on the detected hardware tier
+ 4. The onboarding voice step activates (showing enable/skip options) only when the hardware probe confirms sufficient capability; on hardware below threshold it shows a capability note and skips to the next step
+**Plans**: 2 plans
+
+Plans:
+- [x] 39-01-PLAN.md — Sentence-buffered TTS streaming + multi-language synthesis
+- [ ] 39-02-PLAN.md — Onboarding voice hardware capability probe
