Most eBook apps are for portable devices, but there are some for Windows and Mac computers.
Adobe Digital Editions (ADE) is incorporated into some hardware readers, and there is a free standalone version for use on a Windows or Mac computer. You need this version if you want to read eBooks borrowed from your library, or have bought eBooks from companies like Waterstones or Mills & Boon.
Its features include:
On Windows computers, the screen reader settings control how much punctuation is read and it's possible to move by character or sentence, or to read continuously.
There are some notable limitations:
Blio promised great things when it was announced a few years ago, but has progressed slowly and unevenly.
There are apps for Windows, iOS and Android devices, but features vary between them. For instance, font size options are available in the Windows 8 app but not the Windows desktop app, while speech with the built in voice is the other way around.
You can only buy books from the Windows app.
Speech output is available through the built-in screen reader (but not on Windows 8), and you can buy voices from Blio.
