What type of content is typically not suitable for providing audio descriptions?

The reasoning behind considering content with no visual elements as generally unsuitable for providing audio descriptions lies in the very purpose of audio descriptions. Audio descriptions are intended to enhance accessibility for visually impaired users by narrating visual elements that are crucial for understanding the content.

When content lacks visual elements, there is essentially nothing to describe. For example, if a piece of media consists solely of spoken dialogue with no accompanying visuals or actions, adding audio descriptions would not provide any additional understanding or context. These descriptions are meant to convey information about what is being seen on screen, such as actions, expressions, or important visual cues that contribute to the narrative. Without any visuals, the utility of audio description is significantly diminished, as there are no visuals to interpret or explain.

In contrast, content with significant dialogue may still benefit from audio descriptions by narrating visual action or elements that complement the dialogue. Similarly, content with background music can be described in the context of how it relates to visual elements, and media with plenty of visual elements is ideally suited for audio descriptions to convey the richness of what is occurring visually.
