Building the Next Generation of Conversational AI

In this episode of AI + a16z, Sesame Cofounder and CTO Ankit Kumar joins a16z general partner Anjney Midha for a deep dive into the research and engineering behind their voice technology. They discuss the technical challenges of real-time speech generation, the trade-offs in balancing personality with efficiency, and why the team is open-sourcing key components of their model. Ankit breaks down the complexities of multimodal AI, full-duplex conversation modeling, and the computational optimizations that enable low-latency interactions. They also explore the evolution of natural language as a user interface and its potential to redefine human-computer interaction.Plus, we take audience questions on everything from scaling laws in speech synthesis to the role of in-context learning in making AI voices more expressive.Key Takeaways:How Sesame AI achieves natural voice interactions through real-time speech generation.The impact of open-sourcing their speech model and what it means for AI research.The role of full-duplex modeling in improving AI responsiveness.How computational efficiency and system latency shape AI conversation quality.The growing role of natural language as a user interface in AI-driven experiences.For anyone interested in AI and voice technology, this episode offers an in-depth look at the latest advancements pushing the boundaries of human-computer interaction.Learn more:The Maya + Miles demoCrossing the uncanny valley of conversational voiceSesame CSM 1B modelFollow everybody on X:Ankit KumarAnjney Midha Check out everything a16z is doing with artificial intelligence here, including articles, projects, and more podcasts. Please note that the content here is for informational purposes only; should NOT be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security; and is not directed at any investors or potential investors in any a16z fund. a16z and its affiliates may maintain investments in the companies discussed.
