It seems like you're encountering an issue with Google Speech-to-Text (STT) authentication in LiveKit. Here are some steps to ensure proper configuration: • Google STT authentication can be configured using one of three methods: ◦ Pass credentials directly in the

credentials_info

dictionary parameter. ◦ Save credentials in a JSON file and specify the path using the

credentials_file

parameter. ◦ Use Application Default Credentials (ADC). • Ensure that you are using one of these methods correctly in your setup. Here's an example of how to configure Google STT in an AgentSession:

from livekit.plugins import google
session = AgentSession(
    stt = google.STT(
        model="chirp",
        spoken_punctuation=False,
        # Add your authentication method here
        # credentials_info={...} or
        # credentials_file="path/to/credentials.json"
    ),
    # ... llm, tts, etc.
)

If you continue to face issues, please double-check your credentials and ensure they are valid. Let me know if you need further assistance! Sources: Google Cloud STT integration guide | LiveKit Docs
