Build a real-time voice AI agent by selecting a provider stack for STT, TTS, and LLM, then implementing low-latency audio routing using OpenAI Realtime API and Deepgram to ensure interactions feel instant and natural.

Integrate WebRTC for voice AI audio transport by leveraging LiveKit real-time infrastructure. This provides robust audio routing and low-latency communication necessary for web and mobile voice applications.

LiveKit works with Deepgram to orchestrate high-quality transcription and synthesis pipelines. You can combine LiveKit's real-time infrastructure with Deepgram STT/TTS for robust low-latency audio processing and voice agent deployment.

You can use ElevenLabs voice synthesis in a real-time voice application. It provides scalable voice synthesis capabilities that orchestrate within the pipeline alongside STT and LLM components for natural audio generation.

Real-time voice AI pipelines experience high latency when audio routing and provider orchestration are unoptimized. Apply latency optimization across WebRTC transport and STT/TTS processing to make voice agent interactions feel instant.

You do not need Vapi exclusively; you can use OpenAI Realtime API for native voice-to-voice interaction. Vapi is available for hosted voice agents and quick deployment, offering architectural flexibility based on infrastructure needs.
