Have those lovely people at Texthelp Systems really entered into the spirit of accessibility with their Browsealoud product?
Browsealoud is a piece of free software that you can download to enable you to hear the text content of a website. It works on a PC or a Mac, and you can download a variety of voice packs.
Sounds great, but here's the thing: Browsealoud won't work for just any website, in fact only a limited number out of the millions available are supported.
But that doesn't sound right. Surely a piece of software should be able to read the content of any web page: we already know that search engines can do it, so why not text-to-speech software?
The simple answer is that Texthelp Systems could if they wanted develop their system to work on any site, and use the site's CSS to better read the page, but they probably make far too much money from encouraging web developers to make their sites Browsealoud-enabled.
There are plenty of free browser add-ins that will give you the same (and possibly better) results than Browsealoud can give you, and as long as the page you're reading is developed properly, you'll have no problems.
Browsealoud is just one of many proprietary formats that fragment the web and make things more difficult for end-users.
