## What we know about Rime

This is our verified profile of Rime, a text-to-speech apis platform - enterprise conversational TTS (IVR, contact centers, voice agents) emphasizing ultra-low latency models (Coda, Mist, Arcana) and self-hosted deployment; usage-based pricing with a single published rate. Every fact about Rime below carries the source it came from and the day we checked it.

Rime does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Rime quote, it is the fastest way for us to close that gap.

On capabilities, Rime covers streaming audio output, realtime websocket api, professional voice cloning, word-level timestamps, pronunciation dictionaries, and soc 2 type ii. Each of those is verified against Rime's own docs or dashboard, not marketing copy.

For compliance, with Rime: SOC 2 Type II is in place. If you are in a regulated space, confirm the current posture with Rime before you commit, since these change plan by plan.

Among the 46 text-to-speech tools in our matrix, Rime leads with the 8th-widest language coverage and lags at the 13th-cheapest flagship rate; the fact sheet below has the raw numbers behind that placement.
