Does this have to do with blowing virtual air though a virtual model to
produce a sound? I saw on the telivision show "Beyond 2000" a technology
where they would stick a instrument into a person's throat and map out
their voice box with a laser and make a 3D model of it. With the 3D model
they were able to make the person actually sing using the model. When the
internet VR 'metaverse' comes around in say 5-10 yrs max we will be able to
create characteristic voices for our avatars. Does anyone know of a link to
ongoing research about this topic?

What evolutionary advantage does this pose?
