1. Articulation Disorders: Articulation disorders refer to difficulties in making sounds or producing specific sounds accurately. Commonly, children with this disorder struggle with pronouncing sounds like “s,” “r,” or “th.” The disorder can stem from developmental delays, hearing loss, or physical anomalies. Treatment primarily involves speech therapy that may include exercises to aid the child in learning how to produce sounds correctly.
2. Phonological Disorders: Phonological disorders pertain to difficulties with a language’s sound system. Children with the disorder may experience symptoms including difficulty comprehending sound rules, leading to sound substitutions or omissions. Possible causes may include developmental delays or hearing loss. Treatment typically involves speech therapy, including exercises to improve sound accuracy and use in speech.
3. Fluency Disorders: Fluency disorders refer to difficulties with the cadence or pace of speech. The most prevalent fluency disorder is stuttering, in which an individual repeats or extends sounds, syllables, or words. It can result from genetic factors, developmental delays, or environmental factors. Treatment typically includes speech therapy, which may incorporate methods to help the person regulate their stuttering and enhance their fluency while speaking.
4. Language Delay: Language delay pertains to challenges with acquiring language skills, such as comprehending and utilizing spoken and written language. Symptoms of the disorder include difficulties in following directions, understanding questions, or expressing oneself clearly.

Speech therapy, which incorporates exercises to help the child learn and practice language skills, is the usual form of treatment for language delay.
