Rime

What is Rime?

Rime is a voice AI platform that supplies speech models for production voice agents, IVR and telephony. Its text-to-speech lineup includes Coda v2, tuned for natural expression, and Mist v3, tuned for the lowest latency; the docs describe sub-100ms model latency and 313 Coda voices across 10 languages, plus 78 Mist v3 voices. Rime also offers speech-to-text for English and Spanish, streamed over WebSocket or gRPC, with SDKs for Python, Node.js, Go and Rust. Developers call HTTP and WebSocket APIs, a CLI and an MCP server, and the models plug into LiveKit, Pipecat, Vapi, Daily and similar frameworks. Enterprise teams can self-host in a VPC or on-prem and get SOC 2 and a HIPAA BAA. Pay-as-you-go pricing starts at $0.03 / min for Mist v3 and $0.05 / min for Coda v2, new accounts get free credit, and Enterprise is custom.

Why use Rime

• Two TTS models let you choose between lowest latency with Mist v3 and more natural delivery with Coda v2.
• Streaming over WebSockets with word-level timestamps supports interruption handling in voice agents.
• Self-hosting in a VPC or on-prem keeps audio and text inside your own network when compliance requires it.
• Metered per-minute pricing with no minimum makes costs easy to estimate for variable call volumes.
• Docs include a LiveKit tutorial and starters for Next.js, Express and FastAPI, so a first agent can run quickly.
