Well, today was the last day of the conference. One of the sessions I attended was all about free and low-budget programs for students with disabilities. They featured TTS software, mind-mapping software, and dictionaries. These have been tested by the presenters, and they recommend them to their students, so they should be good. Here are the highlights:
D-Speech (by Dimio)
This a free TTS software that allows the user to save the output as a Wav or Mp3 file. You can also select different voices and to combine them between themselves, in order to create dialogues between some voices. The interface is user-friendly, so even beginners will have an esy time with this. One drawback is that the D-Speech screen always has to open, and it will not read text that is outside of the program. This program also topped their list of MP3 conversion programs.

Natural Reader
This TTS program has a free version and an upgraded version available. The free version works really well, and a bonus is that it has a mini-read bar that can be positioned anywhere on the screen, so it can read any document you have open. The drawback with this one is that it doesn't highlight when it reads.
