SaySo Uses human sounding voices and reads aloud as you type, so you can write confidently knowing you've made less mistakes.
With SaySo you can relax and listen to emails, blogs, essays and books. SaySo highlights the words as they are spoken, focussing your attention, enabling you to better understand the text.
Here is a video on the reading & writing capabilities of SaySo.
As a dyslexic this is great and the simplicity of the interface can really benefit people who are less confident with computers, I would say that it will benefit people who respond to strong imagery as opposed to text or sleeker graphic interfaces.
