What Rime does
Rime is a conversational voice AI company that generates low-latency speech for voice agents in customer service, sales, banking, healthcare, hospitality, and contact centers. Developers and enterprises use its voices through an API, with more than 600 voices, control over accent, pace, and tone, and more than 50 languages with regional dialects. Pronunciation controls handle names and technical terms. The site claims sub-100 millisecond latency, a vendor figure, and lists named customers including Mayo Clinic, LiveKit, and Daily. An option to self-host supports compliance needs. A free trial is offered, and the site links to a pricing page without listing prices.
