What makes a person's voice distinct?

Too many things to count, but I'll generally try to divide it into two broad categories:

1. The way our muscles and cavities are made and aligned. This refers to the composition of the muscles which make up our vocal folds, pharynx, soft palate, etc. Also, the ways the tunnels and tubes in our throat are connected help shape the sound we produce.

2. The way our brain instructs us to produce sound. This means, how we articulate certain consonants and vowels, our various speech patterns when we communicate, and the inflections we use when we breathe and communicate ideas.
