To receive text messages sent via the

send_text

API in Python, you need to register a text stream handler for the topic you expect to receive messages on. Here’s how you can do it: 1. Register a handler for the topic using

room.register_text_stream_handler

. 2. The handler receives a

TextStreamReader

object and the sender's participant identity. 3. You can process the text incrementally as chunks arrive, or read the entire message after the stream completes.

import asyncio
from livekit import rtc

async def main(room_name: str):
    room = rtc.Room()
    # Connect to room (token setup omitted for brevity)
    await room.connect(url, token)

    def on_text_received(reader: rtc.TextStreamReader, participant_identity: str):
        async def _on_text_received():
            # Process chunks as they arrive
            async for chunk in reader:
                print(f"Received chunk: {chunk}")
            # Or read all text at once
            # text = await reader.readAll()
            # print(f"Received complete text: {text}")
        task = asyncio.create_task(_on_text_received())

    room.register_text_stream_handler(
        topic='my-topic',
        handler=on_text_received
    )

    await asyncio.Event().wait()

• Replace

'my-topic'

with the topic you are using for

send_text

. • The handler will be called automatically whenever a text message is sent to that topic. You can process the message as it arrives in chunks, or wait for the entire message to be received before processing. Sources: Sending text | LiveKit Docs | examples/other/chat-stream-receiver.py
