Recently, I've been thinking about the existence of an internal monologue. This is another thing that distinguishes us from animals.
I was surprised at how the inner voice is formed in children. They first say everything out loud. But as the child matures and develops, he learns to regulate his own behavior. Here egocentric speech appears - external, but directed not at other people, but at oneself. With age, the child learns to control his behavior better and better, and egocentric speech gradually turns into an internal one - this process is called internalization.

Russell Holbert, an American psychologist and specialist in inner speech, states that five types of internal experience are available to people: inner speech, inner vision, unsymbolized thinking, feelings, sensory awareness.

If the speech areas of the brain are damaged due to a stroke or injury, aphasia occurs, the inner voice also loses harmony. Patients with aphasia cannot tell if a couple of words rhyme when they are spoken to themselves.

When reading people actually hear the voice. The same brain centers responsible for hearing are turned on. People can describe the voice they hear while reading. https://www.semanticscholar.org/paper/Inner-reading-voices%3A-An-overlooked-form-of-inner-Vilhauer/822a6f34ff5b8de0f87774f3aa185506f795d501
An interesting article about auditory hallucinations.I wondered why people perceive the voices in their heads as not their own. https://serious-science.org/hallucinations-6272
