Larynx Voice Box

How the Larynx (Voice Box) Affects a Child's Development

The larynx, or voice box, holds the vocal folds that turn breath into sound, shaping how a child cries, babbles, speaks and connects with others — while also protecting the airway during feeding. A clear, comfortable voice supports communication, social confidence and safe swallowing, so a persistently hoarse, breathy or weak voice deserves a friendly check.
