World's Fair 2025

Your realtime AI is ngmi — Sean DuBois (OpenAI), Kwindla Kramer (Daily)

Overview

This talk emphasizes the critical role of low latency in building effective voice AI experiences, arguing that current real-time AI is often inadequate. The core thesis is that achieving natural, human-like voice interactions requires a fundamental shift in how audio and video are handled over networks, moving beyond traditional methods like WebSockets to leverage technologies like WebRTC. The speakers suggest that voice is poised to become a primary interface for the next generation of AI applications.

Key takeaways

Notable quotes

*If you want to build a conversational voice experience that people really love, you you're going to stress a lot about latency. Nothing else matters if your AI responds too slowly.*
*Websockets are great if you're trying to deliver audio and you want something really easy that can target all platforms. If you're trying to build a prototype lots of different platforms, websockets the way to go. On the other hand, WebRTC solves a bunch of things around handling giving you high quality audio, high bandwidth, low latency.*
*I'm convinced voice is going to be the core building block of the next generation of UIs, of the UIs for the generative AI era.*
