Usage

The simplest way to use Rime TTS is to pass it to the tts argument in your AgentSession, including the model and voice to use:

from livekit.agents import AgentSession

session = AgentSession(
    tts="rime/arcana:astra",
    # ... llm, stt, vad, turn_detection, etc.
)

import { AgentSession } from '@livekit/agents';

session = new AgentSession({
    tts: "rime/arcana:astra",
    // ... tts, stt, vad, turn_detection, etc.
});

Parameters

To customize additional parameters, use the TTS class from the inference module:

from livekit.agents import AgentSession, inference

session = AgentSession(
    tts=inference.TTS(
        model="rime/arcana", 
        voice="astra", 
        language="en"
    ),
    # ... tts, stt, vad, turn_detection, etc.
)

import { AgentSession } from '@livekit/agents';

session = new AgentSession({
    tts: new inference.TTS({ 
        model: "rime/arcana", 
        voice: "astra", 
        language: "en" 
    }),
    // ... tts, stt, vad, turn_detection, etc.
});

Voices

LiveKit Inference supports all of the voices available in the Rime API. You can view the default voices and explore the wider set in the API in the Rime voices documentation, and use the voice by copying its name into your LiveKit agent session.

The following is a small sample of the Rime voices available in LiveKit Inference.
