text to speech pronunciation version 6

I have instructions for how to edit the text to speech pronunciation for the two English voices, Kate and Paul, but those instructions are for Captivate version 4.

I can't fing the UserDicEng.exe file which is supposed to be in the VT folder.

Does anyone have up-to-date instructions for changing text to speech pronunciation in Captivate 6?

I'm using Windows 7.
