How does the phone know my voice sounds versus others if it is only vibration?

The way a person's voice sounds is comletely determined by the way the air vibrates when that person talks. The vibration of air *IS* sound! Different people have different voices because they produce slightly different vibrations in the air when they speak.
There isn't anything *more* that the phone needs "to know" in order to reproduce the sound of a voice.

The voice you hear on the phone is created by the diaphragm.
How the diaphragm vibrates is dependent on the signal that is transmitted on the line.
The signal that is transmitted on the line is formed when someone talks in to the receiver on the other end of the line.
Every persons voice sends a unique signal over the phone line. It is unique to that person for the same reason why each persons voice is different.

The vibrations you produce when you talk depend on the length and thickness of your vocal chords as modified and resonated by your mouth tongue, lips and nasal passages; not to mention your adopted tone of voice and accent, etc. Just as the gasoline gage in a car is an analog (electronic representation) for the gas remaining, the telephone (diaphragm, magnet and wire coil, or similar) produce an accurate electrical analog of your specific voice. The earpiece in the phone you are calling reverses the process where a wire coil causes a magnet and diaphragn to vibrate exactly like the mouthpiece in your phone, making an exact replica of your speech, recognizable to your friends.

A telephone doesn't 'know' anything. It transmits an electrical signal taken from the diaphragm (microphone). The diaphragm turns sound waves into an electrical signal. The sound waves produced by your voice sound different from the waves produced by my own. That's about all there is to it.

Frequency response is the key your looking for, variations in frequency create vibratory reactions within the diaphragm, the electronic impulses are then transmitted and the same exact frequency responses are then received and reproduced.

telephone is a device. it doesn`t "know" the sound it transmits -
just does it as faithfully to source as possible - even if it`s your voice. call someone now.
