OpenAI Realtime API vs LiveKit for Enterprise Voice

OpenAI Realtime API vs LiveKit for Enterprise Voice

Short summary

A detailed comparison of OpenAI's managed Realtime API versus a self-hosted LiveKit pipeline for enterprise voice agents. OpenAI offers simplicity but locks you into their cloud with limited data control; LiveKit uses WebRTC for low-latency, modular pipelines where you can swap STT, LLM, and TTS components independently. The article includes concrete scenarios — HIPAA-compliant healthcare triage and high-volume delivery driver routing — showing when each approach wins on cost, latency, or compliance.

  • •OpenAI Realtime API is monolithic and managed; LiveKit is modular and self-hosted over WebRTC
  • •LiveKit lets you swap STT/LLM/TTS components and keep data in your VPC for compliance
  • •Real-world scenarios show LiveKit winning on cost at scale and on data sovereignty; OpenAI wins on simplicity
