Best for: Sesame AI
Sesame AI is a voice AI research company behind the viral Maya and Miles conversational demo and the open-weight Conversational Speech Model (CSM), released on Hugging Face. Unlike typical text-to-speech engines, CSM is built for full-duplex conversation — it can be interrupted mid-sentence, respond to tone, and hold a natural back-and-forth exchange with the kind of pacing, breath, and micro-pauses that make voice AI sound human rather than robotic. The Maya/Miles web demo went viral for sounding uncannily realistic, drawing comparisons to how ChatGPT reset expectations for chatbots. Sesame's longer-term goal is a wearable, voice-first companion device positioned against smart-glasses and AI-pin style hardware, with the web demo and open CSM model serving as a preview of the conversational engine that would power it. As of 2026 Sesame monetizes primarily through research partnerships rather than a standard SaaS pricing page, and developers can self-host CSM for free.
