Rime Mist
Rime Mist is an API-based text-to-speech model for real-time voice agents, customer calls, IVR systems, and other spoken applications.
Rime Mist converts written text into conversational speech for voice applications. It supports streaming audio, pronunciation controls, speed adjustment, spelling, multiple languages, and deployment through cloud or self-hosted environments.
It is used by developers and enterprises building customer support agents, healthcare systems, food-ordering services, financial applications, and outbound calling workflows. Mist is not a general-purpose chatbot or text-generation tool; usage is billed by characters, while enterprise deployment and support are custom-priced.
