Screen Reader

Screen readers are tools used by people with vision and reading impairments. Some individuals with low vision will use a screen reader along with a zoomed in view of their screen. Those with reading impairments, such as people with Dyslexia, use them to speed up their reading process.

Screen readers may behave differently based on their DOM models. So, an application – especially a public facing application – should be tested by all the browsers listed below, and in multiple browsers.
