Might it be possible to quantify the the difference between say English and Italian as they are spoken?

Or say English and Russian? I think it is true that although most different languages use most part of the throat and mouth etc. they don't use them in the same proportions. Some languages more throaty some more on the lips. This might give the possibility of dedscription if not quantity.

Misic seems a bit more straitforward. pitch, rhthym, length of notes. Irish songs don't geberally sound like Arabic songs.

Perhaps we can lead the soft sciences to something a bit more concrete?
