Speech Sound Disorder: What Is It?
Speech sound disorder is a communication disorder characterized by persistent difficulties in producing speech sounds. It can involve phonological problems (difficulties producing particular sounds or strings of sounds), problems controlling different parts of the vocal apparatus (such as the lungs or larynx), problems with the timing of speech, or difficulties with speech such as stuttering or lisping. Children with speech sound disorder do not have problems understanding language itself. Rather, they have difficulties expressing language in speech sounds at an age-appropriate level.
