There will be at least 100 LEDs to display moving visual information and the text, specifically, “comprises a song title”. Sony has a smart speaker where LEDs are used to display the time through the fabric of the speaker sides. In the patent, it refers to the gadget we're assuming is the next HomePod as Device 10. Device 10 may analyze a user's voice (e.g., when a user is supplying voice commands such as database queries and/or other commands to device 10). If vocal stress is detected in captured voice information, device 10 may make adjustments to content being presented to the user.
