Rime —AI voices with personality. On-prem and cloud TTS for IVRs and agents people actually want to talk to.

At Rime, we envision a future where voice AI is indistinguishable from human speech, fostering authentic and meaningful connections between machines and people. Our mission is to transform how enterprises communicate by infusing voice AI with the rich subtleties and emotional nuances of real human conversation, making interactions deeply engaging and natural.

We harness advanced speech synthesis models built on the world’s largest proprietary dataset of spontaneous, multilingual conversational speech, empowering our technology to capture laughter, breaths, inflections, and code-switching. This enables us to deliver voice AI that not only sounds human but feels human—advancing communication beyond robotic speech to an immersive, expressive experience.

By combining deep linguistic and sociolinguistic expertise with pioneering machine learning, we are crafting the future of voice AI that drives operational efficiencies, customer satisfaction, and trust across industries, helping enterprises create lasting impact in the connected human-machine era.

We've been tracking voice AI companies for years, and most sound like they're reading a grocery list. That's what makes Rime so refreshing — their voices actually laugh, pause, and breathe like real humans do.

Founded by a Stanford NLP dropout and former Amazon Alexa linguist, this 2022 startup is tackling something ambitious: making AI voices that don't sound robotic. And honestly? They're nailing it.

What Makes Their Voices Different

Rime built their own recording studio in San Francisco to capture something other companies miss — the messy, beautiful reality of how people actually talk. Their dataset includes interruptions, "ums," laughter, and all those little imperfections that make speech feel human.

The result is voices that can code-switch between English and Spanish mid-sentence, chuckle at appropriate moments, and handle the kind of natural conversation flow that usually trips up AI. We're talking about voices that can literally sigh or hum when the moment calls for it.

Enterprise Results That Speak Volumes

Here's where it gets impressive: Rime is already powering tens of millions of conversations monthly for major brands like Domino's and Wingstop. In telecom alone, they've doubled call success rates and cut abandonment by 75%.

That's not just tech demo magic — that's real business impact. When your voice AI sounds more human, customers actually want to keep talking to it.

Who This Really Works For

We see Rime as a perfect fit for enterprises handling high-volume customer interactions where voice quality actually matters. Food service, healthcare, telecom support — anywhere a robotic voice could hurt your brand or lose customers.

The fact that they're SOC 2 and HIPAA compliant means they're serious about enterprise security, not just flashy demos. Plus, with both cloud and on-premises deployment options, they're flexible enough for companies with strict data requirements.

Bottom line: if you're tired of voice AI that sounds like a GPS from 2010, Rime's approach feels like the future we've been waiting for.
