vizact.speak

[mjabon]

Hello. I am having problems making the mouth open more when an avatar is speaking. I am using the following code:

vizact.speak(speechfile,2.0, 'mouth_open', 2.0))

I thought this should amplify the lips by 2. It looks like they barely move their lips. So then I tried making it 10 or even 100 and it did nothing!!

I also don't understand what the 4th argument (threshold) is. I just usually set it to be the same as the scale argument....

thanks!
