What we hear when we speak, however, is air- and bone-conducted sounds. Vibrations from our vocal cords directly reach the cochlea. Our skulls deceive us by, in fact, lowering the frequency of these vibrations along the way, which is why we often perceive ourselves as higher-pitched when we listen to a recording.
“When [someone] listens to a recording of their voice speaking, the bone-conducted pathway that they consider part of their ‘normal’ voice is eliminated, and they hear only the air-conducted component in unfamiliar isolation—what everybody else actually hears,” says Dr. Chris Chang, an otolaryngologist at Fauquier Ear, Nose & Throat Consultants in Warrenton, Virginia.
