Free software for the visually impaired

Hello, the NVDA software is not only free, but it is also one of the best screen readers on Windows. If you want my opinion, I think it is the direct competitor of JAWS. However, with the eSpeak voice synthesizer, which it comes with by default, it's a nightmare to use. On the other hand, if you install other voice synthesizers, which it allows you to do easily, it would be a different story; this is actually one of its strengths. You can download the software from the official site:

and the Eti Eloquence voice synthesizer at the following address:

There you go, I hope this will be useful to you.

Hello
there's the speech synthesis (Virginia's voice) it's great, I've been using it for years.
it's available for free download on Handicap International.

Hello.
There is also the completely free NVDA program that exists. I've been using it for a few years now. But if you have Windows 8, the speech synthesis isn't great. But it's still something!
