How is it possible to change the pitch of our voice from high to low?
What will be an ideal response?
Usually, the tenser the vocal folds, the faster they vibrate and the higher the pitch. To produce deep tones, the glottis widens, and to produce high-pitched tones, the glottis becomes a slit. Intrinsic laryngeal muscles control the true vocal folds and the size of the glottis.
