Rime Arcana

Rime Arcana is a text-to-speech model for real-time voice apps, generating expressive multilingual speech through Rime’s API.

Rime Arcana

Rime Arcana converts text into expressive speech for voice agents, conversational applications, customer support, outbound calling, audiobook narration, and other audio experiences. Arcana v3 supports multilingual code-switching, word-level timestamps, streaming, voice controls, and on-premises deployment.

Developers can use it through Rime’s API, dashboard, or supported voice-agent integrations. Rime’s current pricing page lists general Starter and Enterprise pricing, but does not show a separate Arcana v3 rate; Enterprise deployment, support, and custom voice options cost extra.
