voice-ai

Voice AI architecture and implementation guide. Covers two architectures: speech-to-speech (OpenAI Realtime API, lowest latency) and pipeline (STT->LLM->TTS, more control). Includes provider-specific patterns for OpenAI Realtime, Vapi, Deepgram, ElevenLabs, and LiveKit. Use when building voice agents, voice-enabled apps, or real-time conversational AI.
