## Real-Time Conversational AI Agent - System Requirements

### Core Capabilities

**Voice Processing Pipeline**
- Bidirectional audio streaming with <50ms total latency (VAD + STT + LLM + TTS + network)
- Streaming Speech-to-Text (Deepgram Nova-2 or AssemblyAI with real-time endpoints)
- Streaming Text-to-Speech (ElevenLabs Turbo v2.5, Cartesia Sonic, or PlayHT 3.0-mini for sub-300ms first-byte)
- Voice Activity Detection (VAD) with interrupt handling for natural turn-taking
- Echo cancellation and noise suppression for clean audio in/out

**AI Agent Architecture**
- LLM backbone: Claude 3.5 Sonnet or GPT-4 Turbo with streaming responses
- Function calling / tool use for:
- Web search (Brave Search API, Perplexity API, or Tavily)
- PDF processing (PyMuPDF + semantic chunking + vector embeddings)
- Memory/context retention across conversation
- Async message queue for non-blocking tool execution
- Response streaming with partial sentence cutoff for ultra-low latency

**Visual Components**
- Animated 2D/3D avatar with lip-sync (Wav2Lip, SadTalker, or Ready Player Me + Livelink)
- Phoneme-driven mouth shapes synced to TTS audio output
- Idle animations and reactive gestures triggered by sentiment/keywords
- Canvas/WebGL rendering for 60fps performance

**UI/UX Requirements**
- Dual-pane layout: Avatar viewport (top) + scrolling chat transcript (bottom)
- Real-time bidirectional transcription with speaker labels
- Text input fallback with instant message injection into conversation flow
- Visual indicators: speaking state, thinking/processing, tool execution status
- Audio waveform visualization for user and agent

**Integration Constraints**
- Twitter Spaces audio bridging via virtual audio cable (VB-Cable, Voicemeeter) or OBS virtual camera
- Screen capture output for streaming avatar + chat to Twitter Spaces as video source
- Persistent WebSocket or WebRTC connection for audio I/O
- Local deployment option for lowest latency (no cloud round-trip for audio)

### Technical Stack Recommendations

**Frontend**
- Electron or Tauri desktop app for native performance and audio device access
- React/Vue for UI with Zustand/Pinia for state management
- Web Audio API for client-side audio processing
- MediaPipe or TensorFlow.js for avatar animation (if browser-based)

**Backend**
- FastAPI (Python) or Node.js with Socket.io for WebSocket server
- Redis for conversation state and message queue
- Qdrant or Chroma for vector search on PDF embeddings
- FFmpeg for audio format conversion and streaming

**Infrastructure**
- Single machine deployment: NVIDIA GPU (RTX 4070+) for local TTS/avatar inference
- Cloud fallback: Modal, RunPod, or Replicate for burst compute
- CDN for static assets if web-deployed

### Performance Targets
- First audio response: <800ms from end of user speech
- Avatar lip-sync offset: <100ms from audio playback
- Transcript lag: <200ms behind spoken words
- PDF query response: <3s for semantic search + answer generation
- Concurrent tool execution without blocking voice responses

### Acceptance Criteria
1. Agent can participate in live Twitter Space with <1s response latency
2. Avatar mouth movements match TTS audio output with imperceptible delay
3. Chat window shows live transcription for both user and agent within 500ms
4. User can send text messages mid-conversation without audio interruption
5. Agent autonomously triggers web search when detecting knowledge gaps
6. PDF upload → indexed → queryable in conversation within 10s
7. System handles 60+ minute conversations without degradation
