What the RNIB said about WebAnywhere (Source: RNIB Blog)

All you need to do is switch a PC on, plug in your headphones, execute a couple of keyboard commands so that you open up the WebAnywhere home page, switch it on and away you go. What sets WebAnywhere apart from other text-to-speech software, free or otherwise, is that it can be used on any website rather than only sites where that software is installed. This is fantastic on so many levels:

  • Enables people who can’t afford costly screen readers to access the web
  • Enables people with slight sight problems who don’t yet use a screen reader but may want audio support to have it
  • You can use it on other PC’s and laptops if you’re traveling or unable to access your own i.e in libraries, schools and colleges
  • Enables people with reading problems to get reading and audio support
  • People browsing in a second language can use it to help understand written text
  • Is an additional tool in the web developers toolbox when testing websites for accessibility
