Psychology says people raise their voice pitch when they want you to listen may be doing without realising it

Have you noticed how someone's voice can suddenly become higher when they are trying to make a point? A person may be speaking normally during a conversation, but the moment they feel interrupted, ignored or particularly eager to get someone's attention, their pitch rises. Sometimes it happens without conscious effort. Other times, people deliberately make their voice more expressive when they want an important sentence to stand out.

Psychology and communication research suggest that pitch is an important part of prosody, the rhythm, stress, intonation and pitch patterns that give spoken language social and emotional meaning. A change in pitch can therefore signal that something deserves attention, even when the actual words remain the same.
