I understand, it seems we don’t agree but thank you for participating in the discussion.

I would argue that the points you make strengthen my analogy, because all of them can also be said of DC electrical current.

Speech, like all sound, is a wave that moves back and forth parallel to the direction of motion. This is the context that I describe it as AC.

DC as in direct current, while AC is alternating current.

I don’t understand you point. Is what way is talking like frequency modulation?
