The disclosed techniques provide dynamically controlled notifications that improve inclusiveness in online meetings. The dynamically controlled notifications can be audio or visual indicators that supplement a first notification. A user input causes the display of the first notification, an image of a “virtual hand raise.” The input also invokes a timer for measuring an elapsed time from the time of the user input. The system also analyzes audio streams to detect topic transitions of a discussion of the meeting participants. Then, the system generates dynamically controlled notifications in response to at least one triggering event, either (1) in response to detecting that the timer has reached a time threshold or (2) in response to a detection of that the discussion has transitioned to a new topic. In some embodiments, the dynamically controlled notifications are invoked in response to either of the two triggering events, whichever event is detected first.
