Lisping

This character suffers from lisp.

A lisp, also known as sigmatism, is a speech impediment in which a person cannot articulate sibilants ({s}, {z}, {ʒ}, {ʃ}, {tʃ}, {dʒ}). These misarticulations often result in unclear speech. This disease mostly affects children. There are physiological and social factors that may cause a lisp. For example, long chronic diseases, specific mouth anatomy (including the teeth broken in a fight), the unwillingness of parents to correct the pronunciation of a child, as well as heredity and more.
