I was pretty sure you were supposed to be able to change Openbook to use SAPI synthesizers, so I did a bit of digging to give it a trial run.
I still haven't gotten the Microsoft TTS SAPI driver to work yet, but it is probably because I haven't gotten the name correct to pass along to Openbook.
In the following instructions I found at Freedom Scientific's web site, it says if you remove the semi colon from one of the lines, a pop up is supposed to appear at Openbook's start to indicate what SAPI drivers are installed and available, but I have yet to come across this screen, and not for want of trying. I finally went into JFW's Change Synthesizer menu under their language option and found the names of available SAPI tts engines there.
I downloaded one of the free Lernout & Hauspie's SAPI4 engines for British English from Next Up, which I've been able to get working.
When my patience returns, I'll try to get one of my SAPI 5 tts engines working as a further trial run for AT&T's Natural Voices.

How can I make additional SAPI synthesizers available to OpenBook?


1. Using Modify from the OpenBook CD, you should install Microsoft SAPI. You must make that the default synthesizer at this point. This will add a new file
to the OpenBook directory called SSILSAPI.INI.

2. After Microsoft SAPI is installed for OpenBook, you should edit the SSILSAPI.INI file to remove the semicolon in front of the line that says "engine=show".
This allows the pop-up dialog to be displayed when OpenBook is launched. This pop-up dialog will give you the critical information about the exact name
of the engine. You use this name exactly as written or SSIL will not understand what you are requesting.

3. Now that the you have the exact engine name, you must edit the SSILSAPI.INI file one last time. This time, it's to tell it RealSpeak is one of the choices.
Whatever the pop-up dialog for RealSpeak lists should reflect exactly what needs to go in the SSILSAPI.INI. In this example the pop-up dialog for RealSpeak
displays "L&H Speech RealSpeak" this is what needs to go in the SSILSAPI.INI file.

The lines in the file would look like this:

engine=L&H Speech RealSpeak

I don't think you can use them with Open book. as OB doesn't allow you to
change synths, at least I haven't been able to find.

When I first installed them, they did slow things down a bit, but after
doing a defrag and a scandisk, things got back to normal.

I do notice that if I am scanning in grayscale and 400 dpi and using the
Naturals, that sometimes them entire voice part of Kurzweil won't work.
This happens rarely but is annoying which is why I use the Naturals for
reading after the scan is done.

I have played with Text aloud, I think it is called from www.nextup.com

and it works well.
