Sesame AI is a company focused on natural voice interaction technology, delivering advanced conversational speech models and intelligent hardware to create more natural, emotionally engaging voice assistant experiences.
Its core technology is the Conversational Speech Model (CSM), an end-to-end model that directly generates speech with natural rhythm, emotion, and contextual awareness, rather than simply converting text to speech.
The voice assistants (such as Maya and Miles) are designed to mimic subtle features of human dialogue, including emotional responsiveness, natural pauses, and tonal variation, to provide more human-like interactions.
According to public information, Sesame AI offers a research preview and online demos for users to try. For commercial plans, pricing, or advanced features, please refer to the official documentation for the latest details.
Based on current technical benchmarks, the Conversational Speech Model is optimized primarily for English; performance for other languages may vary. Please check the official docs for multilingual support.
According to its demo pages, voice interaction data may be temporarily recorded for quality assurance and will be deleted after a certain period. For specifics, review the official privacy policy.
