It is absolutely possible to send a message or otherwise communicate with a user while a function is being called and the user is waiting. The LiveKit Agents framework provides structured mechanisms for this, including: • Verbal status updates using the agent's speech system (e.g.,

session.generate_reply()

or

session.say()

) to inform users of progress during long-running operations. • Advanced control with

SpeechHandle

objects to coordinate communication and detect interruptions while operations are ongoing. • The ability to provide additional cues such as background audio or custom frontend UI updates to represent operation status. This approach is specifically recommended for actions taking more than a few hundred milliseconds or those involving significant operations, to maintain a responsive and user-friendly experience.
