Accessibility requirements related to text alternatives (links to technical specification) They also act as labels to identify audio, video, and files in other formats, as well as applications that are embedded as part of a website. Text alternatives serve as labels for controls and functionality to aid keyboard navigation and navigation by voice recognition (speech input). For instance, they can be read aloud for people who cannot see the screen and for people with reading difficulties, enlarged to custom text sizes, or displayed on braille devices. Text alternatives can be presented in a variety of ways. For instance, an appropriate text alternative for a search button would be “ search” rather than “ magnifying lens”.

Some aspects of accessibility require more technical skills or advanced knowledge of how people use the Web. Some accessibility requirements are easy to meet, yet understanding the basics of how people with disabilities use the Web helps implement them more effectively and efficiently. Standards play a vital role in defining accessibility requirements for each of these components.

More background is provided in Essential Components of Web Accessibility. To create such text alternatives, authors need authoring tools that support them to do so. This information needs to be processed by web browsers and then conveyed to assistive technologies, such as screen readers. For instance, web content needs to include text alternatives for images. These components inter-relate and support each other.
