Start here
Pick the one that matches what you’re doing. Each is a complete path, not an overview.Generate your first audio
One HTTP request, a playable file back, in about five minutes. Start here if you are evaluating Rime or adding speech to an existing backend.
Transcribe speech
Transcribe your first recording with Rime speech-to-text, then read the overview for the constraints every integration shares: English or Spanish, and one utterance per stream.
Talk to a Prism voice agent
Talk to your own Prism agent through your microphone. The overview explains how Prism, Rime’s speech-to-speech API, runs the whole conversation.
Build a real-time voice agent
A conversational agent that listens and speaks. Complete LiveKit tutorial, or direct WebSocket starters for Next.js, Vite, Express, Node, and FastAPI.
Try Rime from the terminal
Generate and play speech without writing any code. The fastest way to hear a voice and check response speed.
Run Rime on your own infrastructure
Deploy supported models in your VPC or fully on-premises, so audio and text stay inside your network.
Diagnose a failing text-to-speech request
What each status code and WebSocket close code means, what the client observes per transport, and what to capture for support.
Rime at a glance
Talk to the team about enterprise, on-prem, or volume pricing
Custom deployments, compliance (SOC 2, HIPAA), SLAs, and dedicated support for production scale.
Start with Coda
Coda is the recommended model for new projects. Send requests tocoda.api.rime.ai, and the host selects Coda, so a request needs no modelId. The legacy WebSocket endpoints on users-ws.rime.ai serve Mist v3 unless you set modelId: coda, as the API cheat sheet shows.
Coda pairs an LLM backbone with a dedicated speech inference engine trained on full-duplex conversations between real people. Through the cloud API, it serves ten languages: English, Arabic, Dutch, French, German, Hindi, Italian, Japanese, Portuguese, and Spanish. Each voice speaks one of them, so start from the language your application needs and choose among that language’s voices.
Speech capabilities
Generate speech
Turn text into playable or downloadable audio in formats suited to web, mobile, telephony, and media workflows.
Stream speech in real time
Use HTTP for simple streaming responses or persistent WebSockets for the tightest conversational loop, with timestamps and interruption handling.
Shape how speech sounds
Guide delivery, pacing, spelling, pauses, pronunciation, and the way numbers, dates, and other text are spoken.
Build voice agents
Begin with a complete LiveKit tutorial or connect Rime directly from Next.js, Vite, Express, Node.js, or FastAPI.
Connect voice platforms
Integrate with LiveKit, Pipecat, Vapi, Daily, SignalWire, VideoSDK, and other voice application frameworks.
Create a custom voice
Create a branded enterprise voice and use it through the same speech API as Rime’s catalog voices.
Run Rime in your environment
Use Rime’s cloud API or deploy supported models on your own infrastructure.
Developer surfaces
Dashboard
Explore, preview, and save voices, generate speech, and inspect normalized text. Create API tokens, follow setup progress, manage teams, and review usage and billing.
HTTP, WebSocket, and gRPC APIs
Generate complete audio responses, stream audio, receive word timestamps, transcribe speech over WebSocket or gRPC, list voices, and use Rime’s language tools.
Application code
Call the HTTP and WebSocket APIs with standard clients from any server-side language, without a Rime SDK. For speech-to-text, the Rime SDK for Python, Node.js, Go, and Rust is the quickest start. The cheat sheet is the compact parameter and endpoint reference.
CLI
Generate, play, and save speech, inspect usage, and test response speed from the terminal.
MCP server
Let Claude, Codex, and compatible tools browse voices, generate samples, inspect pronunciation and text normalization, and scaffold integrations.
Application integrations
Use Rime with supported voice-agent frameworks, telephony services, deployment platforms, and application builders.
