Welcome Anne!
Yes, both Zaba (frog) and Hal (TV) do perform
lipsync (lips move) when they reply to a question.
If you are having problems in this regard, please
let us know some particulars like:
Are you using Windows 98, XP...
Do you have other programs that use speech and if so,
are they working?
Click on the M when talking with Hal to go to the Options
menu or select Options when you first start Hal.
Select the Speech menu
Check the box in the upper left that reads Use Speech Synthesis (Hal Speaks)
Click Apply, OK, then Chat with Hal.
Just say Hello of something and see if the character's lips move with their response. If not let us know and we'll do what we can to help you!!
