The following information is meant to help in the creation of accessible PowerPoint presentations so the content is available to all users. PowerPoint presentations tend to be very visual so for those with low vision or using screen readers, accessibility is key. Many of the concepts covered here can also be found in Creating Accessible Word Documents.
Slide titles act as a way to navigate through the presentation using a screen reader and also provide information about the content of each slide. Slide titles should each be unique and specific to each given slide. If you want a title to be invisible on a slide but still voiced by the screen reader, do the following:
Screen readers read through the content on a slide in a certain order, including the title, text, and alt text. To ensure the slide contents are read in the order intended, set the reading order by doing the following:
Avoid using text boxes that are not part of the native slide layout as they appear as graphic elements to screen readers and the content may be inaccessible. This is true if the slides are converted to HTML or PDF as well.
Adding alt text to all visual elements in a presentation allows those using screen readers to understand and access the content more readily and effectively. Decorative elements do not need to contain alt text, but any visual element containing content relevant to the presentation should. Alt text should, when possible, be short and to the point.
Best practices for adding alt text to images are the same as for Word Documents.
The steps for adding alt text to shapes, charts, or tables are the same as above for SmartArt.
To make audio and video resources accessible, make sure there are captions provided with the media and if possible, a transcript as well.
Best practices for creating tables and lists are the same as for Word Documents.
The steps for using the Accessibility Checker are the same as for Word Documents.
