Steve, first of all the voice in question is no longer called Scansoft Tom. Since Scansoft was acquired by Nuance all of the Scansoft voices have been renamed to Vocalizer. There for the voice in question you are looking for is now called Vocalizer Tom not Scansoft Tom.

As for the Vocalizer voices such as Tom you have to purchase the version for your adaptive software. It is no longer sold as a stand alone Sapi voice and is only sold as an add-on for your screen reader or similar adaptive software. So if you want a version for Jaws, NVDA, Text Aloud, those require separate licenses and must be obtained through your adaptive technology manufacturer.

@Steve, if you have the cd for jaws8 or lower, you should have all of that scansoft voices.
I currently don't have the cd for jaws at the moment, but I still have those voices copied, but I can't share it here, unless I got the permission from Dark or other moderators tell me to share them, I'll happy to help. but I'm afraid the copyrights...

You mentioned earlier in this post a voice called Donna. Where can this be found, and isn't it AT&T Cristal? Sometimes I hear that voice on the phone whenever I call certain places.
