Is it all about the vocal cords, everyone has unique vocal cords/
the harmonics of sound production in the human body in general/chemical signals in the brain moderate it? Do identical twins usually have pretty similar sounding voices? There are billions of people on earth, and so many subtle differences that make us all sound unique.

There are many factors including the length and thickness of vocal chords and the volume and shape of the throat and mouth that resonate (or interfere with resonating) that affect the sound being produced. If you pluck a guitar string at its center it will vibrate only its lowest (fundamental) tone. If you pluck the string nearer either end it may sound the fundamental but will also supply a richer mix of overtones (higher frequency). Male voices can usually be identified because they contain the fundamental (and overtones) while female voices usually omit the fundamental. This has to do with the volume of the resonator and the length and thickness of the vocal chords. Bass drums sound deeper the greater their volume. Church bells have a characteristic "bell" sound you can recognize because they can not produce the lowest fundamental tone that goes with their series of overtones. And we haven't even mentioned accents and proper use of the voice (a little nasal?) and good projection (speak from the mask!) or native language that may not include all the common sounds of English. They tell the story about the Japanese man who was hired by a company to take care of supplies. He used to jump out of dark corners and shout Supplies!!!

I am an identical twin, and we do sound very much alike. I think people's unique voices have many causes. The shape of your sinuses causes different tones from different people...the thickness of your vocal chords, how fast or slowly you push air past your vocal chords etc... Also, you learn certain patterns from the people around you. If you live in New York and move to Kentucky, soon you will pick up their accent, AND their vocal tones. If they speak at a higher pitch, you will start talking at a higher pitch too.

Some good technical answers given, but noone has picked up on our childhood development.
It has been shown that we cannot reproduce sounds that we have not already heard. We are strongly influenced by what we hear as young children.
Our brain develops sensitivities to specific patterns of frequencies.
In practice this affects how good we are at learning foreign languages. A child who hears other languages in the first year will tend to be better at learning and speaking languages.
So there are strong influences from our family.

I've found my voice is very similiar to my sisters. When we were at home no one could tell us apart on the phone.
