How is every person’s voice unique?

The title says it all.

I was just wondering how it’s possible that every single person’s voice is so unique to each other? It’s all the same systems, the same organs, so how does everyone sound so different? I understand it to a certain extent, but would like to have it explained!

I’ve seen a lot of biology posts, but I’ll throw out a more audio based explanation. While we think of our voices as a single audio stream, you can break it down into component parts (using something like Fourier Transforms) that show low/mid/high frequencies the same way music producers can mess around with tracks in a studio. Every voice is a combination of sounds at each frequency, and there can be as many different voices as combinations. And that’s just tone. Once you throw in different accents, inflections, and vernaculars, there are a huge number of combinations. A lot of this is influenced by biology, but people can also clearly train themselves to talk with a certain accent or tone. Identical twins can sound the same because they have the same biology, but also sound different if they inflect differently.
