Abstract: Techniques for selectively requesting feedback from users are described. A system may receive a user input and perform an action responsive to the user input. The system may determine whether feedback should be requested from the user. Such determination may be based on various signals such as the user's present emotional state, whether the user input included profanity, whether the user input interrupted an output of the system, etc. When the system determines feedback should be requested, the system may select a feedback prompt pre-established by a domain, skill, or the like. After the system outputs the response to the user input, the system may output the feedback prompt.

Abstract: A time-shifted digital content item is played via a playback screen, and an updateable companion timeline associated with the time-shifted digital content item is accessed. The updateable companion timeline includes one or more timeline events, and each timeline event has a trigger time corresponding to a playback time in the time-shifted digital content item. Responsive to reaching a playback time that matches a trigger time of one of the one or more timeline events during playback of the time-shifted digital content item, the timeline event having that trigger time is rendered.
