Reliability
For the calls you can't get wrong
When the voice is talking to a patient, a cardholder, or a hotel guest deciding whether to stay the night, quality stops being a nice-to-have. Rime delivers the speed real conversations need and runs inside your own environment when compliance demands it.

voices
A voice for every conversation
Choose from 600+ voices, then shape accent, pace, and tone until it fits your brand and your industry. What comes out sounds like a person who wants to be on the call and not a system working through a script.

Built by linguists
Rime was founded by people who study how language actually works. That's why our voices land the rhythm, stress, and warmth of real speech instead of the hollow tones you hear everywhere else. We treat voice as a craft, not a feature to bolt onto a stack.

From the teams that put us on the line
"Mist v3 on a co-located endpoint has been a 3x latency improvement for us. We're consistently seeing sub-100ms TTFB in production — that's the difference between a conversation that feels human and one that doesn't."
Ali Mansoor
Founding Engineer, Trillet AI
"The latency stays low even under heavy loads. It's a true enterprise production-grade system."
Pratik Mundra
Co-Founder, SigmaMind AI
"It was clear that the voice made a real impact on the phone. When guests feel comfortable right away, everything else goes more smoothly."
Rahul Aggarwal
Founder & COO, ConverseNow
"In healthcare, the voice is the first point of trust. Patients need to feel heard, not processed — and that starts with how the AI sounds and how fast it responds."
Jack Ryan
Co-Founder & Chief Product Officer, Attune

"Mist v3 is incredibly fast and deterministic pronunciation is a game-changer. When you're powering live conversations at scale, you can't have a model guessing brand names or proper nouns."
Tom Shapland
Product Manager, LiveKit
Questions, answered
How good are the voices?
From banking to food ordering to healthcare, you can shape accent, pace, and tone to fit the moment. When a use case carries strict compliance requirements, Rime can run entirely inside your own environment.
How fast are the voices?
Rime is engineered for real-time conversation, with latency low enough that the natural back-and-forth of a live call never breaks or feels like a wait.
What languages do you support?
Real fluency across 50+ languages, plus regional dialects and accents — with the same pronunciation controls to get names and terms right every time.
Can I try it, and will it work with my stack?
Yes — start for free and drop Rime in through a simple API, or self-host when you need to. Most teams are up and running the same afternoon.
Do you have customers I'd recognize?
Rime powers over 1.5 million minutes of conversation for teams across fintech, healthcare, hospitality, and more. A few of them are quoted just above.
