Do agent messages go to all participants in a multi-participant room?

LiveKit-Community · January 21, 2026, 1:33pm

This question originally came up in our Slack community and the thread has been consolidated here for long-term reference.

If I have multiple participants in the same room and the agent responds, does that message go to all participants?

Or do I need separate rooms for each user?

Yes, audio published by the agent is received by all other participants in the room.

If you need 1:1 interaction with the agent, you would need separate rooms for each user.

To distinguish between participants in a multi-participant room:

room.local_participant is the agent itself
room.remote_participants gives you all other participants

See this example for sending messages to remote participants:

main


      
              
          payload = {
              "type": update_type,
              "data": data or {}
          }
          
          logger.info(f"Emitting state update: {update_type}")
          
          try:
              room = userdata.ctx.room
              remote_participants = list(room.remote_participants.values())
              
              logger.info(f"Found {len(remote_participants)} remote participants to notify")
              
              for participant in remote_participants:
                  try:
                      await room.local_participant.perform_rpc(
                          destination_identity=participant.identity,
                          method="game_state_update",
                          payload=json.dumps(payload)
                      )
