All information has to go through a medium. That could be a number of things, from the very obvious like sound travels through air in waves or relative high density to the ambient air around it. To information being coded into a human cypher for emotions and experience, much like what you are looking at now. The written word in all its forms is a substitute for something else humans can experience. Like love, pain, caring or even just the colour blue. The medium of language is a lot more complex a medium then something like sound. Its a hybrid medium, it will go through a lot of physical mediums as well as conceptual ones.
Experience > Thought > Movement > Sound > Electrical Conversion > Interpretation > Reaction.
This on a very basic level is communication using voice from one person to another.
Experience; drawing upon things that have happened in the past, how to communicate as well as how not to, this makes more sense when you have things you should not say in context.
Thought: Converting this into words that best suit what you are trying to say and then converting that into muscle movement such as the jaw, vocal cords and diaphragm.
Movement: Literally the movement of those muscles to push air past the vocal cords to create vibrations of low and high pressure that are then tweaked by the mouth and jaw.
Sound: The finished product of the person sending the speech. Sound passing out the mouth, nose and body towards the person it is spoken to.
Electrical Conversion: Sound converted into electrical signals that are then interpreted by the brain.
Interpretation: The brain interprets this information and lays it upon experiences of language and life to understand what the other is saying.
Reaction: The cycle continues.
Its quite a complex way to communicate and yet we can even do it using written words as well as sounds, which are even abstracted from the spoken noises.
(Note to self: Get to the point.)
