TDE for the blind

I am shortly giving a talk on TDE. I shall laud it as a desktop for the partially sighted, but shall say that it appears to be less friendly to the totally blind, in that it does not seem to have a screen reader. Is that correct? Any points that people would particularly like mentioned? In fact, any pointers? I shall use TDE 3.10.13.2 on Wheezy. I considered upgrading to 14, but if it goes wrong I haven't a lot of time to reinstate (because I am a bit over-stretched at the moment.) I need to use my own desktop because some of the things that I want to demonstrate I can't really set up anywhere else. E.g. KMail. I need mail! I am open to contradiction on that. But I am so familiar with 3.10.13.2, and it is mostly going to be a live demonstration. I don't want to do too much eerm.... let me see ...... I am bound to do some! Thanks. Lisi
