vizact speak

[krimble]

Hi all,
I'm trying to make one of the "Complete Character Pack" avatars to speak. The thing is I keep getting the same error message:

Loading File: avatar2\casual15_f_highpoly.cfg
** Load Time: 0.59 seconds
** ERROR: Bone with name '' does not exist
** WARNING: Cannot run speech action on avatar, no face or jaw bone was specified

female = viz.add("avatar2\\casual15_f_highpoly.cfg")
speech = vizact.speak('jfk.wav', threshold = .1, scale = 0.7, sync = True)
female.add(speech)

In the .cfg file I saw the 3 available morphs. The blinking and eyebrow morphs are working fine.
How do I get the mouth morph to work with the vizact.speak function?

Thank you!

Kind regards,
