Dan,
What Jay is saying was that he already tried the Haptek Sapi Config program and although it finds the voice and it can be selected, Hal will start up with that selected voice but will not speak with it.
One has to go into the OPTIONS menu > SPEECH then select another voice, wait a few seconds (for the selection to take), then select the Kate 16 voice, APPLY, OK, then back to chat with Hal.
When one finishes chatting and closes Hal, upon restart (next day or whenever), one has to go through the same process all over again!!
I feel your frustration Jay because I have to deal with the same issue! I really do like the Kate 16 voice but the selection process thing is quite aggravating.
Without reinstalling Hal, I don't have an answer to this problem.
Robert? Any takers?
