Sesame AI Voice Model

Sesame AI Voice transcends traditional voice assistants by achieving true "voice presence". Using our groundbreaking CSM technology trained on over one million hours of audio data, it creates voice output so realistic that users often cannot distinguish it from human speech. Unlike Siri or Alexa that simply process commands, Sesame AI Voice engages in genuine conversations with emotional intelligence, remembering context and building trust over time.

Sesame AI Voice combines sophisticated emotional intelligence with advanced contextual memory. It analyzes conversation context to respond with appropriate emotional tones, recognizing whether you're excited, thoughtful, or need reassurance. The system maintains coherent dialogues by tracking conversation history and user preferences, creating natural interactions that feel more like talking with a thoughtful companion than a machine.

Currently, Sesame AI Voice performs best in English while offering emerging multilingual capabilities. Thanks to our diverse training dataset, it can understand and adapt to a wide variety of accents and speech patterns. We're actively expanding to support over 20 languages in the coming months, ensuring the same level of natural voice quality and emotional intelligence across all languages.

We take privacy seriously with a privacy-first design approach. Sesame AI Voice processes voice data locally whenever possible and uses state-of-the-art encryption for cloud interactions. We maintain full transparency about data usage, and users have complete control over their voice data, ensuring a secure and trustworthy experience.

Yes! We're committed to open collaboration. Key components of Sesame AI Voice are available under an Apache 2.0 license, and we provide comprehensive development tools and APIs. Our developer platform makes it easy to integrate our advanced voice capabilities into your applications while maintaining the same high quality of natural interaction.

We're developing fully duplex models for even more natural conversation flow and turn-taking. Our roadmap includes expanding language support, increasing model scale, and enhancing emotional intelligence capabilities. We're also exploring new features to make interactions even more engaging and personally meaningful.
