<p>A computing device may provide a control interface that enables the user to manage synchronized output of companion content (e.g., text and corresponding audio content). A visual cue may be displayed identifying a current location in text corresponding to a current output position of companion audio content. The cue may be advanced during audio presentation to maintain synchronization between the output position of the audio content and a corresponding position in the text. In some embodiments, synchronized output rnay be controlled by dragging a finger across the text displayed on the touch screen. A visual indication rnay be provided depicting the distance between the advancing position in the text and the current position of the user's finger. In further embodiments, the speed at which the audio content is presented and the visual cue is advanced may be adjusted based at, least in part on a user's performance on a task (e.g., a speed on an exercise machine).</p> |
