# Requirements Archive: v1.6 Voice Pipeline + Minimal Message Bridge
**Archived:** 2026-04-04
**Status:** SHIPPED
For current requirements, see `.planning/REQUIREMENTS.md`.
---
# 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
