Currently using spectrum & on scene when characters aren’t talking the is a description of what is happening. I don’t know how this was turned on & don’t know how to turn it off.
In the Spectrum TV app, hit the star button on your remote, check the captions and make sure they are off. Also, go to accessibility and language within the app, and make sure you don't have descriptive audio turned on in those settings.
Wrong language or verbal description of action on screen when watching program
Some programs contain multiple audio tracks that can be selected, such as different languages or verbal action descriptions for the visually impaired.
The Roku default method of accessing your choice of audio track is to press the * key on your Roku remote while viewing the program and examining the options supported by that channel.
But more and more channels are not using the Roku default but instead substituting their own method of access -- I'm guessing this is so they will have consistent controls with versions of their app running on platforms other than Roku. Often these options are accessed by pressing the up and/or down cursor control keys while viewing the program to pop the channel's own control options on the screen.
