Listen to what the voice follows
Roku documents four Star presses as a screen-reader on/off shortcut. If speech began after repeated button presses and now follows highlighted menus, inspect Accessibility, Screen reader. That behavior differs from a narrator describing action within a film.
The distinction chooses the correct control. A programme audio menu cannot turn off spoken Home Screen navigation, while a screen-reader switch cannot remove an audio-description track embedded in the selected programme.
Change the intended layer
Use the screen-reader settings if the goal is to change interface speech. If spoken navigation is useful, keep it enabled and adjust its rate instead of treating the activation as a fault. Explain the shortcut to the other household users.
If the voice continues only inside one programme, inspect that title’s actual audio track. Keep the observation specific rather than resetting the whole television because an unfamiliar voice appeared.
Check the next normal action
Move through a simple menu after the change and confirm the desired spoken behavior. Then return to the programme and inspect it separately. These two checks establish which layer changed.
A useful support description says whether speech follows focus, appears only during video or began after four Star presses. It avoids a vague report that the device “changed language” when the interface is simply being read aloud.
