What are the three basic types of speech impairments?
There are three basic types of speech impairments: articulation disorders, fluency disorders, and voice disorders.
Language disorders or language impairments are disorders that involve the processing of linguistic information. These problems may be receptive (involving impaired language comprehension), expressive (involving language production), or a combination of both.
- Adults: Signs of Speech & Language Disorders
- Struggles to say sounds or words (stuttering)
- Repetition of words or parts of words (stuttering)
- Speaks in short, fragmented phrases (expressive aphasia)
- Says words in the wrong order (expressive aphasia)
- Struggles with using words and understanding others (global aphasia)
- The following are brief definitions of several of the more prominent speech disorders:
- Apraxia of speech.
- Developmental verbal dyspraxia.
- Orofacial myofunctional disorders.
- Speech sound disorder.
- Voice disorders.
- Specific language impairment.
- Expressive language disorder is a communication disorder in which there are difficulties with verbal and written expression. Expressive language disorder affects work and schooling in many ways. It is usually treated by specific speech therapy, and usually cannot be expected to go away on its own.
Speech refers to the actual sound of spoken language. Language refers to a whole system of words and symbols—written, spoken or expressed with gestures and body language—that is used to communicate meaning. Just as speech and language differ, there's a difference between speech disorders and language disorders.
- Speech delay, also known as alalia, refers to a delay in the development or use of the mechanisms that produce speech. Speech – as distinct from language – is the actual process of making sounds, using such organs and structures as the lungs, vocal cords, mouth, tongue, teeth, etc.
- Speech disorders or speech impediments are a type of communication disorder where 'normal' speech is disrupted. This can mean stuttering, lisps, etc. Someone who is unable to speak due to a speech disorder is considered mute.
- Language disorders or language impairments are disorders that involve the processing of linguistic information. These problems may be receptive (involving impaired language comprehension), expressive (involving language production), or a combination of both.
