What is the physical reason why people, particularly of similar body compositions, don’t all have similar vocal timbres?

I’m not talking about accents or the reason we might have similar voices to our parents — because we learn how to speak from them. Do an X ray of two people’s throats or diaphrams or whatever….I assume they will look largely similar. Why might one have a high pitched voice; the other a deep resonant one? Etc.

Because there are several bodyparts involved that modulate the air flow. Each part is influenced also by genetics which is why voices are so different. With training one can achieve quite a huge change as well despite the natural voice being the same

P.S. from the top of my head those parts are tongue, lips, teeth, nasal and oral cavities etc
