    # ... stt, llm, vad, turn_detection, etc.
)

session = new AgentSession({
    tts: "deepgram/aura-2:athena",
    // ... stt, llm, 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="deepgram/aura-2", 
        voice="athena", 
        language="en"
    ),
    # ... stt, llm, vad, turn_detection, etc.
)

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

session = new AgentSession({
    tts: new inference.TTS({ 
        model: "deepgram/aura-2", 
        voice: "athena",
