OpenAI rebuilt its WebRTC stack to power real-time voice AI with low latency, global scale, and seamless conversational turn-taking. This technical endeavor focused on optimizing their infrastructure for highly responsive AI interactions.
This post details a solution for building real-time voice streaming applications. It leverages Amazon Nova 2 Sonic and Amazon Kinesis Video Streams WebRTC to overcome common development challenges, covering the solution's architecture, implementation patterns, and practical examples.
Live streaming has historically grappled with trade-offs between low latency and scale, or seamless ad delivery and complex infrastructure. New technologies like Media over QUIC (MoQ) and SCTE-35 are emerging to resolve these issues, with MoQ aiming to combine WebRTC's interactivity with HLS/DASH's scalability.
