I am using google stt

To help you fix the

APIConnectionError

with Google STT in LiveKit, here are some friendly steps you can follow: 1. Verify Credentials: Double-check that your Google STT credentials are set up correctly. You can use a credentials file, a credentials info dictionary, or Application Default Credentials (ADC). Here's an example:

from livekit.plugins.google import STT as GoogleSTT

google_stt = GoogleSTT(credentials_file="path/to/service-account-key.json")

2. Check Network and API Endpoints: Make sure your network connection is stable and you’re using the right endpoint for your region (like

us-central1

,

global

, etc.). 3. Diagnose Errors: Turn on detailed logging to get more insights into what might be going wrong:

import logging
logging.basicConfig(level=logging.DEBUG)

4. Verify API Quotas: Head over to your Google Cloud Console to confirm the Speech-to-Text API is enabled, your quotas haven’t been exceeded, and your billing is active. 5. Adjust Connection Parameters: Sometimes increasing timeout and retry settings can do the trick:

from livekit.agents import APIConnectOptions

conn_options = APIConnectOptions(timeout=30.0, max_retry=3, retry_interval=2.0)

6. Implement a Fallback Mechanism: To keep things running smoothly, consider using multiple STT providers as a backup:

from livekit.agents.stt import FallbackAdapter
fallback_stt = FallbackAdapter([google_stt, other_stt], max_retry_per_stt=1)

Hopefully, these tips help you get past the error and make your setup more reliable. If you run into any other bumps or need a hand, just let me know—I’m here to help! Sources: livekit-plugins/livekit-plugins-sarvam/livekit/plugins/sarvam/stt.py
