 When interacting with these clients, you can use them very similarly to how you'd use the common `websockets` library:
 
 ```python
 import os
 
 from hume import AsyncHumeClient
+from hume.empathic_voice.types import UserInput
 
 client = AsyncHumeClient(api_key=os.getenv("HUME_API_KEY"))
-async with client.expression_measurement.stream.connect() as hume_socket:

+    await hume_socket.send_user_input(message=UserInput(text="Hello!"))
 ```
 
-Model configuration (e.g. face, language, prosody) is sent per payload when you send data (e.g. via `send_publish()`, `send_text()`, or `send_file()`), not at connect time.
-
 The underlying connection, in this case `hume_socket`, will support intellisense/autocomplete for the different functions that are available on the socket!
