Audio Guide settings 
Audio Guide settings help users who are blind or visually impaired to configure the 
text-to-speech reader, enabling them to operate their TV more easily. Audio Guide 
uses voice prompts that speak volume and channel changes, menu options, and 
setting changes. Access Audio Guide settings from the Home screen by navigating to 
Settings > Accessibility, and then select from the following options in the Audio Guide 
section: 
•  Audio Guide – Turn Audio Guide on or off. 
•  Speech rate – Select one of four speeds at which to hear spoken guide 
information: Slow, Normal, Fast, or Very Fast. 
•  Volume – Select the volume at which to hear spoken guide information, relative 
to the main TV volume. 
•  Shortcut – Enable or disable the shortcut feature. When enabled (the default), 
pressing Þ four times in quick succession enables or disables the Audio Guide.
