Build with the next wave of realtime voice AI. In this Build Hour, you’ll learn how to use GPT-Realtime-2, GPT-Realtime-Translate, and GPT-Realtime-Whisper to build low-latency voice agents that can translate live speech, reason across tools, operate apps, and support more natural voice-to-voice and voice-to-action experiences.
In this session, Teri Yu (Product) and Erika Kettleson (Solutions Engineering) will cover: • Building with new realtime audio models for translation, streaming speech-to-text, and intelligent voice agents • Using GPT-Realtime-2 capabilities like preambles, 128K context, parallel tool calling, domain understanding, context over turns, and controllable expressiveness • Creating voice-powered workflows for shopping and product analytics dashboards • Customer Spotlight on how Sierra (https://sierra.ai/) is designing production customer experience agents with guardrails, VAD tuning, tracing, redaction, evals, and customer-specific harnesses.
