Continuing from the previous Live Stream on this Lip Sync Mini-Series, I demonstrate how to setup the CHOPS network to allow Houdini to recognize certain phoneme values from your voice by building a phoneme library. This allows Houdini to identify these syllables from another script audio file that will be used for lip sync with your character mesh.

In the previous Live Stream, I introduced a set of HDA tools I created for the whole Lip Sync process, but that only deforms or blends the character mouth movements to each phoneme value. You’ll see need CHOPS to analyze the speech audio spectrum and recognize these phoneme mouth shapes. Then using the CHOPS data, you can map it according to the speech audio and thus creating Lip Sync animation using just speech.
