Description: Our anatomy usually causes us to hear a difference between our "inside" and "outside" voice. The purpose of this study was to discover if the degree of this difference is the same from person to person. The procedure was to have a number of participants to record their voice and then listen to it. They were then asked to use software to adjust the pitch to match the voice they hear inside their head. The results were then plotted onto graphs so that they could be compared and interpreted.
