I've found the speech recognition engine (MS engine 5.1) to be rather difficult to use. In that it doesn't always recognize the words properly. I don't have this but some have reported good results with Dragon Naturally Speaking which is only around $100 for the standard version.
Now for the voice. The voice I've found that closest matches KITT's so far is William by Cepstral - the link is to the demos page. You'll want to change the pitch to one lower from default to get it closer to KITT I think. Their voices are around $30 apiece but you can download a demo of it to try in Ultra Hal Assistant if you want. William... Hmmm... as in William Daniels? I was thinking about that.

And to top it off, why not have a Vox display in Ultra Hal Assistant just like KITT? here you go: thecolor
And there you go- KITT!

Now, to get him knowledeable about the KR universe. The AI learns by chatting with you. But can also read and learn from a text file. You can put one sentence per line, like "KITT is a black Trans Am" or "I am a black Trans Am" or "I am the Knight Industries Two Thousand" without quotes into a text file. Then right click on the AI icon or go into the menu, Learn from a Text File... and then be sure that you UNcheck the option to switch the first and secon person stuff. Also before doing that, you want to set the Brain to the highest level of learning (in the Brain tab in General Preferences).
While I know the voice isn't exact, it's almost close. And with the Vox display and a little bit of programming of phrases, you can get KITT talking.

So there you have it... A KITT!


Hmmm... now if one can get the AI to randomly play the scanner sound...
