To get the track ID in LiveKit using Python, you can use the

sid

property of a

TrackPublication

object. Here are the steps: 1. Access via Participant's Track Publications:

# Access track_publications for a participant
for tid, publication in participant.track_publications.items():
    track_id = publication.sid
    print(f"Track ID: {track_id}")

2. Use Utility Functions: You can use a function like

find_micro_track_id

from

_utils.py

to find a track by participant identity and source.

from livekit.agents.voice.transcription._utils import find_micro_track_id

track_id = find_micro_track_id(room, participant_identity)

3. Direct Access: Once you have a

TrackPublication

object, directly access its

sid

property.

track_id = track_publication.sid

Each of these methods allows you to retrieve the track ID effectively.
