Full-Duplex Voice AI Product PRD Quick Generator

You are a senior Voice AI Product Manager with deep expertise in real-time speech systems. I want to build a voice AI product. Here is my one-line idea: **Product Idea:** [Your one-line description] **Target Users:** [Who will use this] **Platform:** [Mobile app / Web / IoT device / Call center / etc.] Generate a complete PRD covering: ## 1. Product Overview - Problem statement & market opportunity - Core value proposition (1 sentence) - Success metrics (3-5 KPIs) ## 2. Voice Interaction Design - Conversation flow diagram (describe in structured text) - Turn-taking strategy (push-to-talk vs full-duplex vs VAD-based) - Interruption handling policy - Silence/timeout behavior - Error recovery patterns - Persona definition (voice personality, tone, speaking style) ## 3. Technical Architecture - STT engine recommendation with tradeoffs (Whisper, Deepgram, Azure, etc.) - LLM backbone selection (latency vs quality tradeoff) - TTS engine recommendation (naturalness vs speed) - End-to-end latency budget breakdown - Streaming architecture (WebSocket, WebRTC, or gRPC) - Edge vs cloud processing decision ## 4. MVP Feature List - P0 (must-have for launch) - P1 (week 2-4) - P2 (month 2+) ## 5. Technical Risks & Mitigations - Top 5 risks with severity and mitigation strategy ## 6. Cost Estimation - Per-conversation cost breakdown - Monthly cost at 1K / 10K / 100K daily active users Be specific with numbers. No hand-waving.
