LiveKit Inference
Use LiveKit Inference to access xAI TTS without a separate xAI API key.

from livekit.agents import AgentSessionsession = AgentSession(tts="xai/tts-1:ara",# ... stt, llm, vad, turn_detection, etc.)
Parameters
To customize additional parameters, use the TTS class from the inference module:
from livekit.agents import AgentSession, inferencesession = AgentSession(tts=inference.TTS(model="xai/tts-1",voice="ara",language="en"),# ... stt, llm, vad, turn_detection, etc.)
