The person, of course!
Most people don't speak to brains.
My friend I'm sorry but you sound like a primitive person...
1) Speaking. There are several areas of the brain that play a critical role in speech and language. Broca's area, located in the left hemisphere, is associated with speech production and articulation. When somebody gets a stroke, one of the commonest symptoms is that he can not speak.
2) Hearing. Your inner ear turns the sound waves into electrical signals. The auditory nerve then sends those signals to your brain. Some brain areas are then used to compare the signals coming from the two ears to figure out where the sounds came from. Other brain areas decode or process language.

Not meaningful .. is history a bunch of atoms, or is it more than that?
History is not a bunch of atoms. It is
about trillion upon trillion of atoms
"at the most basic level,
your body—and, in fact, all of life, as well as the nonliving world—is made up of atoms, often organized into larger structures called molecules....everything you are, including your consciousness, is the byproduct of chemical and electrical interactions between a very, very large number of nonliving atoms, So as an incredibly complex being made up of roughly 7,000,000,000,000,000,000,000,000,000 atoms, you'll probably want to know some basic chemistry as you begin to explore the world of biology, and the world in general."

I know you will not change your mind and I don't want you to, either, but at least you will learn something.
There is no point in further discussion, unless you want to propose your own alternative theory.
