Description

This class provides viseme related operations including reading an audio source and creating a viseme clip out of it. It can also add and remove keys from the viseme clip as well as provide Text-to-Speech capabilities. A viseme track within the timeline will show viseme clips and mouth shapes (viseme keys). The lip options track also includes the viseme smooth clip which can be used to smooth out the transition between the different mouth shapes in the event of a lip-sync animation.

Member Functions

LoadVocal ( self, pAudio, kStartTime, strClipName )

Create a viseme clip for this character with a given audio source.

Parameters

pAudio [IN] Audio source object - RIAudioObject

kStartTime [IN] Clip start time - RTime

strClipName [IN] Clip name - str
