Screen Readers

NVDA: NVDA, or NonVisual Desktop Access, is a free screen reader.  This can be used to check the reading order of your document or webpage, as well as elements such as alternative text and ordered lists.

JAWS: JAWS is the most widely-used screen reading technology on the market.  Much like NVDA, screen readers can help with determining if a document's reading order is correct and if certain elements are tagged correctly.  The drawback to JAWS is that there is a fee to use the software and the licensing can be expensive.   

VoiceOver: VoiceOver is the screen reader built into iOS enabled devices.  There are YouTube videos available on how to activate and use the service.
