Rime pricing
Rime builds speech models for voice agents, with a particular focus on phone conversations. Prism, released in October 2026, is its speech-to-speech model: it hears the caller's audio directly and speaks its reply over one WebSocket, so a team does not have to wire together separate transcription, language and speech services.
That simplicity comes with limits. Prism speaks English only, offers four voices, and has no choice of language model. It takes PCM audio rather than telephone formats, so a phone line needs a conversion step.
Rime also sells text to speech and streaming speech to text. Those are priced differently from the services compared here, so this site ranks Prism only and leaves the rest to Rime's own pricing page.
