What is a Speech and Language Disorder?

Speech and language disorders affect communication and learning. They affect the way the child expresses ideas and understands what has been said.

Types of Disorders

  • Articulation Disorders: Children with articulation problems cannot produce certain speech sounds either in isolation or within blends with other speech sounds. Difficulties with the way sounds are formed and strung together, usually characterized by substituting one sound for another (wabbit for rabbit), omitting a sound (han for hand) or distorting a sound such as “sip” for ship. Whether misarticulating is considered to constitute a speech disorder depends on the child’s age and what is appropriate for that level of development.
  • Phonological Processes/Oral Apraxia: Difficulty with blending and sequencing production of sound. Often with additional oral motor weaknesses.
  • Delayed Language: Characterized by a marked slowness in the development of the vocabulary and grammar necessary for expressing (expressive vocabulary) and understanding (receptive vocabulary) thoughts and ideas.
  • Phonemic Awareness: Difficulty discriminating and manipulating individual phonemes (sounds) in order to produce fluent reading decoding.
  • Reading Comprehension and Written Expression: Difficulty with reading comprehension or expressing ideas in written form secondary to underlying language weaknesses.
  • Pragmatics/Social Skills: Weakness in the many skills necessary to negotiate daily social interactions.
  • Fluency: An interruption in the flow or rhythm of speech characterized by hesitations, repetitions or prolongation of sounds, syllables, words or phrases.
  • Voice Disorders: A child’s voice is determined by age, sex, emotions, and situations, and changes rapidly as the child grows. A child may speak with inappropriate pitch (too high, too low, never changing or interrupted by breaks); loudness (too loud or not loud enough); or quality (harsh, hoarse, breathy, or nasal). The quality of the voice may be hyper nasal as when sounds are emitted through the nose, or denasal sounding as though the child has a stuffed nose. Breathiness and harshness may be to improper use of vocal cords. Prolonged hoarseness or harshness of the voice may indicate a possible medical problem and an Otolaryngology examination may be recommended.
