Hi there! To help you figure out whether a message is user-typed or agent-generated using the Python SDK, you can use the

conversation_item_added

event. This event gives you a

ChatMessage

object that includes helpful metadata to identify where the message came from. Here are the key fields you’ll want to check: •

role

: This tells you who sent the message. If

role == "user"

, it means the message was typed by the user. If

role == "assistant"

, then it was generated by the agent. •

generated

: This is a boolean that shows if the message was created by an agent from user transcription. Here’s a quick example to illustrate:

from livekit.agents import ConversationItemAddedEvent

@session.on("conversation_item_added")
def on_conversation_item_added(event: ConversationItemAddedEvent):
    msg = event.item
    if msg.role == "user":
        print("Message is user-typed.")
    elif msg.role == "assistant":
        print("Message is agent-generated.")
    print(f"Generated from transcription: {msg.generated}")
    print(f"Message ID: {msg.id}, Timestamp: {msg.timestamp}")
    print(f"Content: {msg.message}")

Using this method, you can confidently distinguish between messages from users and agents. If you have any questions or need further help, feel free to ask—I’m here to support you!
