Introduction

One of the essential aspects of creating accessible content is ensuring that individuals with disabilities can access and understand the information being conveyed. PowerPoint, a widely used presentation software, offers features that help improve accessibility by generating alternative text (alt text) for images and closed captions for videos, making the content more accessible for people with visual or hearing impairments.

Generating Alt Text for Images

Alt text is a textual description provided for images in a document. It helps individuals who are visually impaired or using assistive technologies understand the content of an image. PowerPoint allows users to generate alt text for images automatically, making the process of adding alt text quick and efficient.

To generate alt text for an image in PowerPoint, follow these steps:

  • Select the image you want to add alt text to.
  • Right-click on the image and select "Edit Alt Text."
  • In the Alt Text pane, click "Generate a description for me."
  • Review the generated alt text and make any necessary edits to ensure accuracy and clarity.
  • Click "Close" to save the alt text.

By utilizing the alt text feature in PowerPoint, you can enhance the accessibility of your presentation for individuals who rely on screen readers or other assistive technologies to access information.

Closed Captions for Videos

Closed captions are text representations of the audio content in a video. They are essential for individuals who are deaf or hard of hearing, allowing them to read what is being spoken in the video. PowerPoint offers the option to add closed captions to videos embedded within your presentation, ensuring inclusivity and accessibility.

To add closed captions to a video in PowerPoint, here are the steps:

  • Select the video you wish to add closed captions to.
  • Right-click on the video and choose "Edit Video" from the options.
  • In the Video Options pane, under the "Playback" tab, check the "Play in Background" box.
  • Click on "Playback" in the ribbon, and then select "Closed Captions."
  • Enter the captions manually or import a caption file, such as SRT (SubRip Subtitle) or VTT (WebVTT) files.
  • Adjust the timing and formatting of the captions as needed.
  • Click "Close" to save the closed captions.

By adding closed captions to your videos in PowerPoint, you ensure that individuals with hearing impairments can understand the spoken content, making your presentation more accessible to a broader audience.

Conclusion

PowerPoint offers several accessibility features to help users create inclusive and accessible presentations. By generating alt text for images and adding closed captions to videos, you can enhance the accessibility of your content for individuals with visual or hearing impairments. Creating accessible presentations ensures that important information is accessible to everyone, promoting an inclusive and equal learning experience for all participants.
