MathPlayer 2.1 was released in September of 2007 and included the ability to work with screen readers and other AT to speak math expression. Its use has grown each year, with a huge jump in the number of expressions spoken in the last few months (the start of the school year) as you can see below:
Counting the usage from 2007, almost 3 million expressions have been spoken by MathPlayer since it was released! That's a lot of math being spoken to people who otherwise would not have been able to access the content. If you or your students have been waiting for math accessibility to catch on, wait no longer.
We've seen increased interest from vendors in connecting up with MathPlayer, but not all vendors fully support MathPlayer. If your AT software is not listed in our AT math support page or if the functionality you want (eg, Braille or synchronized highlighting) is not supported by the AT you use, contact your vendor and let them know you'll buy an upgrade if they add the support. Vendors listen to their customers. The more often they hear a feature request, the higher priority it becomes for them to add it to their product, so make sure you let them know that math accessibility is important for you.
