Rime

What Rime does

Rime provides conversational voice models designed to make voice AI feel more human. They leverage deep linguistic and machine learning expertise to bridge the gap between humans and machines, bringing warmth, authenticity, and emotional nuance to digital interactions. Their technology aims to create conversations with machines that feel like talking to real people, driving results such as increased call success and sales. Rime offers a wide range of voices, multilingual fluency, and controls for accent, pace, and tone, built by linguists to capture the rhythm, stress, and warmth of real speech. Their proprietary dataset of full-duplex, spontaneous speech forms the foundation for their models, which can be deployed in the cloud, VPC, or on-premise.

AI approach

Rime focuses on making voice AI sound and feel human by blending advanced ML with deep linguistic and sociolinguistic insight.
