Answers:
Sounds are made by vibrations. If you take a violin, for example, and play a string, it will make a sound. If you cut that string in half, it will play the same sound but one octave higher. You have reduced the length of the string, thereby making the vibrations faster.
When you talk about voices, you have vocal chords. At puberty your vocal chords gain mass, so they vibrate more slowly, making your voice deeper. This happens to a greater extent with men than with women, though it happens to both.
Any condition that affects the length of one cycle of a vibration, is a determining factor in the sound made.
VIbration. Whether the vibration is large or small determines what the pitch of a sound will be. Put 'pitch' and 'sound' in your search engine to get more information.
