Can I self-host Rime?

Yes. Enterprise plans support on-premises deployment via Docker Compose or Kubernetes, keeping all audio and text within your network.

What integrations are supported?

Rime integrates with LiveKit, Pipecat, Vapi, Daily, SignalWire, VideoSDK, and others via API or WebSocket.

How is pricing structured?

Usage-based: Starter is $0.03/1K chars for Mist, $0.05/1K chars for Coda. Enterprise uses custom volume pricing with SLAs.

What determines TTFA latency in practice?

TTFA depends on model choice (Mist is faster), concurrency, and deployment location. Co-located endpoints yield sub-100ms TTFB.

How does pronunciation control work?

Rime offers both automatic text normalization and inline pronunciation control via prompting to handle names, addresses, and alphanumerics correctly.

What are the word-level timestamp capabilities?

Coda model provides word-level timestamps for precise interruption handling in voice agents. Mist v3 does not support this feature.

Rime

Rime is a voice AI platform specializing in ultra-low-latency, neural text-to-speech (TTS) designed for real-time conversational applications like voice agents, IVR, and telephony. Its core models, Coda and Mist v3, are trained on full-duplex conversations between real people, enabling natural-sounding speech with sub-100ms model latency. The platform offers over 500 voices across 50+ languages with granular control over accent, pace, and tone. Targeted at developers and teams building production voice systems, Rime provides a simple API for cloud deployment, with enterprise options for self-hosting in VPC or on-premises environments to meet compliance needs (e.g., HIPAA, SOC 2). It's engineered for the high-reliability, low-latency demands of live customer interactions in sectors like finance, healthcare, and hospitality.

Product information

Everything worth knowing about Rime

The complete picture — from everyday features to the technical detail builders and IT folks dig for.

Core features

What it actually does

Real-Time Conversation TTS

Engineered for real-time conversation with latency low enough that natural back-and-forth never breaks. Optimized for production voice agents, IVR, and telephony.

Extensive Voice Catalog

Choose from 600+ voices, then shape accent, pace, and tone to fit your brand and industry. Real fluency across 50+ languages with regional dialects and accents.

Pronunciation & Speech Control

Granular controls for spelling, pause, pronunciation of names/terms, and playback speed. Get it right, every time.

Developer-Friendly Integration

Simple API or self-hosted deployment. Integrate with popular stacks like LiveKit, Pipecat, Twilio, and more. Most teams are up and running the same afternoon.

Enterprise-Grade Deployment

Deploy on-premises, VPC, or cloud via Docker Compose or Kubernetes. Includes SOC 2 Type II reports and HIPAA BAA.

Technical capabilities

Conversational Voice Models

Flagship model 'Coda' is trained on full-duplex conversations for natural expression. 'Mist v3' model is optimized for ultra-low latency.

Low-Latency Performance

Coda model achieves sub-100ms model latency (sub-200ms end-to-end cloud). Mist v3 achieves ~70ms self-hosted latency with sub-50ms TTFA.

What's great

Sub-100ms latency feels natural for real-time conversation
600+ voices with fine control over accent, pace, and tone
HIPAA & SOC 2 compliant with on-prem deployment option

Technical strengths

Built-in pronunciation control for brand names and proper nouns
Word-level timestamps enable precise interruption handling
Self-hosted via Docker Compose or Kubernetes for full control

Where it falls short

Enterprise pricing not transparent; requires sales call
Free tier limited to 20 concurrent TTS generations
Coda model has fewer languages (9) than Mist v3 (4)

Technical limitations

Custom pause feature is 'Coming soon' for Coda model
Word-level timestamps not available on Mist v3 model
