[Blindmath] mathspeak

Thu Jan 12 13:36:34 UTC 2017

ClearSpeak was developed in part with federal funds and is an open specification. Anyone is free to implement it.

Dear Sina,

I've just had a look at clearspeak. It indeed seems to be much mroe
reasonable.

On a related issue, does someone know what is the license for
clearspeak? For example if I wanted to implement a mathematics screen
reader for linux, would I be able to use clearspeak without paying any
fees etc.? I couldn't immmediately find any licensing info on
www.dessci.com

Best,
Łukasz
