Quizplus · Accepted Answer

By forcing a large volume of air out of the glottis and increasing the tension on her vocal cords, Kyley is producing a high-pitched and loud sound. This is because the increased tension on the vocal cords results in them vibrating at a higher frequency, creating a higher pitch, and the forceful expulsion of air adds to the volume of the sound.
