Usage

To use Cartesia, pass a descriptor with the model and language to the stt argument in your AgentSession:

from livekit.agents import AgentSession

session = AgentSession(
    stt="cartesia/ink-whisper:en",
    # ... tts, stt, vad, turn_detection, etc.
)

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

session = new AgentSession({
    stt: "cartesia/ink-whisper:en",
    // ... tts, stt, vad, turn_detection, etc.
});

Parameters

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

from livekit.agents import AgentSession, inference

session = AgentSession(
    stt=inference.STT(
        model="cartesia/ink-whisper", 
        language="en"
    ),
    # ... tts, stt, vad, turn_detection, etc.
)

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

session = new AgentSession({
    stt: new inference.STT({ 
        model: "cartesia/ink-whisper",
