OpenAI has rebuilt its WebRTC (Web Real-Time Communication) stack to support real-time voice AI. This allows for low-latency conversations that can be scaled globally. The new system enables seamless conversational turn-taking, which is essential for natural-sounding dialogue. According to OpenAI, this rebuild was necessary to meet the demands of large-scale voice AI applications. --- Why it matters: This matters because it shows how a major player in AI is addressing the challenges of real-time voice interactions at scale. Engineers and researchers can learn from OpenAI's approach to building low-latency systems that support conversational AI. Source: https://openai.com/index/delivering-low-latency-voice-ai-at-scale
