I'm trying to make a website more accessible to people with intellectual disabilities. I was thinking about putting very simple and easily recognized buttons on the webpages which play mp3's (without opening a separate window, and the mp3's should only start playing once you press a "play" button).
I only know HTML and CSS so far, but as far as I can see, a flash audio button might do just the thing I'm looking for. I'm either looking for a single stand-alone button which reads out an mp3 file of an easy-to-understand version of the webpage, or 3 buttons (play, stop, rewind).
I'm using Mac OSX and don't have a Windows emulator.
I came across this website which seems to offer just the thing I'm looking for: http://www.sonicmemo.com/
I was wondering if something like this could be done for free, without the need for software, and if so - how?? I was also wondering how accessible/usable this option would be.
Any help would be greatly appreciated :)
