Answer 2

I am just going to state what I think, I would gladly like anyone to correct me. Also be forgiving with spelling errors.

In a way, I have thought about this. We can all see ourselves as elongated equations, instead of numbers it is made up of feelings which are attached to audio, visual, tactile or other sensory input. Ontop of that we process alot more unconciously than what we realize conciously. Our brain is set up in a way to emulate and predict something before we realize an answer. Within fractions of a second your brain excites neurons which essentially emulate understandings of other equations. What I am saying is that the brain runs emulations of how we think people would behave. If you have ever been in a lucid dream, in early days you will notice you have no control over how people behave. In a way I think these people would draw from these subconcious understandings, but I would like to also say that these people are usualy experimental and expressive. They would generaly enjoy playing with the sounds they can make. They most likely have and understanding in controling their own voice. Alot of us even if we don't like to admit it when we try to sing we usually begin by mimicing how we understand a sound is made. Through experimentation and time, we can either invent an identity in our voice or sing how we are expected to, like the saying "saying what they want to hear". Some people will naturally pick up accents better than others. Simply being immersed in a different accent sometimes leads people to adjust their accent accordingly. Because they would begin to express on parts of the language that they enjoy. Usually nothing overly absurd, in a way predicting what would be acceptable.
Ultimately we believe we are unique when we are mostly an unconcious sum. And an overminding of the concious logical In most cases strictly bound by moral and social obligations, over subconcious feelings which most tend to filter out due to anxiety and pressures over past failures which were never recieved well.
But for the ones who have discovered a hidden understanding, in a way able to repeat expressions, they just gathered a lot of information to add to their equations.

Your voice is produced by the larynx, which works by vibrating thin stips of tissue. There are muscles that can pull these strips tighter to produce a higher pitch or relax them to produce a lower pitch. It works kind of like guitar strings. Your voice is a product of the length and thickness of your vocal folds (the thin stips of tissue in your larynx) and the tension you typically put on the vocal folds.
