Speech Sound Disorder in Adults

ICD-10 Code: F80.9

Speech sound disorder is part of a cluster of diagnoses called communication disorders. Communication disorders are a group of psychiatric conditions that include:

  • Language Disorder
  • Speech Sound Disorder
  • Childhood-onset Fluency Disorder (Stuttering)
  • Social (Pragmatic) Communication Disorder

A communication disorder is an impairment in the processes of speech, language or communication. Speech is the expressive production of sounds and includes an individual’s articulation, fluency, voice and resonance quality. Language includes the form, function, and use of a convention system of symbols (i.e., spoken words, written words, sign language, pictures) in a rule-governed manner for communication. Communication includes any verbal or nonverbal behavior that influences the behavior, ideas, or attitudes of another individual. An adult with a communication problem may exhibit many different symptoms. These may include difficulty following directions, attending to a conversation, pronouncing words, perceiving what was said, expressing oneself, or being understood because of a stutter or a hoarse voice. An assessment of speech, language and communication abilities must take into account the individual’s cultural and language context, particularly for individuals growing up in bilingual environments.

What is Speech Sound Disorder?

Information and prevalence data on speech sound disorder in adults is limited. Most adults remediate any speech sound difficulties in childhood with speech and language therapy. If problems persist, they are typically attributed to an acquired or neurological impairment such as dysphagia or apraxia.

The cause of speech sound disorders in most adults is unknown.
