Accessibility of E-Resources: Browsers and devices

Browsers and devices

There is a diverse selection of applications, extensions, and tools for listening and reading content online. For example, you can download screen readers to your personal computer or smart devices either free of charge or for a small fee. These screen readers read the content of the webpage out loud to the user.

Most browsers already have built-in accessibility features. Likewise, most mobile devices have their own screen readers as well. In addition, frequently used office programs have similar features. Different software meant for reading PDF files, keyboard-based screen readers for blind people, as well as other programs are also available. Reading applications that use gestures or key commands usually require a bit of practice at first. 

There are several listening and reading aids listed on Celia's website.

DATERO, an ICT-center for special needs groups, provides information and instructions on listening, using text-to-speech tools, improving concentration, and how to alter materials on different devices (only in Finnish and in Swedish).
