I would recommend also checking it with GW Micro's Windows-Eyes screen
reader. It's not as well known as standards like JAWS but that's likely to
change because they're partnering with Microsoft now to make it free for
anyone who owns a license of Office 2010 or later. It's being promoted
through state Talking Book services programs and others.
The web address for the free download is:

JAWS and other ZoomText will probably still be used by institutions who
already have them but this will probably gain a lot of traction among those
looking for a free(ish) product.
