About this episode

This episode explores the engineering and design challenges of building production-grade voice AI systems at scale.

This episode is brought to you by the MLflow team. Check out more information at MLflow.org . What does it actually take to build voice AI at a billion-interaction scale? This episode features an ex-Amazon voice AI engineer who built customer support systems handling 2 billion+ interactions — now working on next-gen voice agent platforms. Anurag digs deep into the real engineering tradeoffs, design patterns, and use cases that separate production-grade voice agents from demos. Voice Agent Use Cases // MLOps Podcast #372 with Anurag Beniwal, Member of the Technical Staff at ElevenLabs 🎙️ Topics covered: 🔹 Cascaded vs. speech-to-speech — Why cascaded systems still win in production, and how to make them feel natural without sacrificing control 🔹 Latency masking — Foreground/background model architecture and how to buy yourself time while deep retrieval runs 🔹 Constellation of models — Using Haiku for tool calling, fine-tuned smaller models for response generation, and why "one model for everything" breaks at scale 🔹 Turn-taking & ASR challenges — Why voice is harder than chat: accents, noise, silence detection, and domain-specific fine-tuning 🔹 Level 1 vs Level…
