Screen Reader Resources
Screen readers are assistive technology software programs that allow blind or visually impaired users to read the text that is displayed on the computer screen with a speech synthesizer or braille display.
When testing your website for accessibility issues, it is recommended that you use a screen reader to evaluate your content from this perspective.
