David asks:

Where does the sound of the inner voice, the voice that only you can hear, come from? As far we know there are no extra vocal chords in the head or little speakers inside the head that cause the sound of the inner voice.

Can you help?

It comes out of your brain, and feeds into your brain via neural impulses.

Just like the voices we hear when we are dreaming, when there are no external sounds.
