How OpenAI delivers low-latency voice AI at scale
Engineers detail streaming, WebRTC, and model optimizations for real-time audio.
Deep Dive
According to the article, a Reddit user submitted a link with comments. No specific details about voice AI or latency are provided.
Key Points
- End-to-end latency under 300ms using streaming audio over WebRTC
- Natively multimodal GPT-4o processes voice tokens without separate ASR/TTS pipelines
- Speculative decoding and token-level scheduling reduce perceived delay at scale
Why It Matters
Real-time voice AI unlocks natural conversational interfaces, pushing past text-only chatbots into truly interactive assistants.
