How to set Blendshape automatically

[hansolGib]

hello, I'm trying to load or instantiate vrm character at runtime and lip-sync it according to the audio at runtime. if I use a character already in the scene, it's working without any issue as I already assigned the blend shape to the corresponding Phoneme. but it seems lip-sync is not working when I instantiate or load a new character. I found it is because the new character's facial blend shape is not assigned to Phoneme and blend shape in U lip sync blend shape. How can I assign the blend shape to Phoneme automatically? Since I use vroid characters, they all have same blend shape such as Fcl_MTH_A,Fcl_MTH_I,Fcl_MTH_U.
