Hi Skutt,
There are 3rd party voices available and some use a different readback engine of their own to provide less robotic sounding sounds.
If you're not successful in locating one in a web search you may want to post in the MS Speech newsgroup below.
=============
I sometimes find it convenient to use the text to speach option in Word but I
find the computer generated voices offered are a bit too mechanical in how
they sound. Are newer synthesized voices available for Word?>>
