Getting Started
Adobe Acrobat can be used to make documents more accessible so that people who use assistive technologies, like text-to-speech readers, can engage with the content of the document. Text-to-speech tools need to use the information "embedded" within a digital document to fully describe the content to the user. Materials like paper handouts, scans from textbooks, photos of text, and hand-written documents are not accessible for users that rely on screen readers unless additional measures are taken. To make these types of documents accessible:
- Scan the material to generate a PDF.
- OCR (Optical Character Recognition) scan the PDF to convert the text into machine-encoded text.
- Add metadata to the document so that an application can "read" the title of the document.
- Add alternative text to images, figures, graphs, maps, charts, and other visual material in the document.
Scanning the Document
If the document is printed media, first scan the document and save it as a PDF. When you scan the pages, make sure they are straight on the scanning bed and keep the material as still as possible.
