Kuwait MOH Speech-Language Therapist key terms

A systematic, rule-governed simplification pattern that young children apply to speech sounds, such as final consonant deletion or fronting, which typically fades as the child's sound system matures.

The ability to notice and manipulate the sound structure of spoken language, including syllables, rhymes, and individual phonemes, without relying on written letters.

The smallest unit of sound in a language that can change meaning, such as the /p/ in pat versus the /b/ in bat.

A predictable sound variant of the same phoneme that does not change word meaning, such as the aspirated /p/ in pot compared with the unaspirated version in spot.

Two words that differ by only one phoneme, such as key and tea, used in assessment and in contrast-based treatment to build a child's phonemic distinctions.

An umbrella term for difficulty producing or organising speech sounds correctly, covering articulation errors and phonological pattern errors that reduce intelligibility.

A client's ability to produce a target sound correctly when given a model, phonetic placement cue, or gradual cueing hierarchy, which informs prognosis and target selection.

A treatment method that contrasts error sounds with sounds that differ on many phonetic dimensions at once, such as place, voice, and manner, to drive broad system-wide change.

A persistent difficulty with understanding or using language that is not explained by hearing loss, intellectual disability, or another biomedical condition, and that affects everyday functioning.

An older diagnostic label for language difficulty in a child with otherwise typical development and nonverbal ability; many such children are now described as having developmental language disorder.

Systematic transcription and measurement of a client's spontaneous speech, yielding measures such as mean length of utterance, type-token ratio, and grammatical accuracy.

The average number of morphemes per child utterance in a representative language sample, widely used as a rough index of expressive grammatical development.

The ability to tell a coherent story with a setting, characters, a sequenced plot, and a resolution, an important bridge between oral language and later literacy.

An acquired language impairment caused by brain damage, most often left-hemisphere stroke, affecting production or comprehension of spoken and written language while cognition is otherwise preserved.

Difficulty retrieving words, especially names of objects and people, which is the most common and persistent symptom across aphasia types.

An error in speech sound or word selection, either phonemic (sound substitution within a word) or semantic (substituting a related word), typical of aphasic output.

A motor speech disorder caused by damage to the central or peripheral nervous system, producing weakness, slowness, or incoordination of the speech musculature.

A motor planning disorder in which the speaker has difficulty programming the movements for speech despite intact muscles, producing inconsistent distortions and groping articulatory attempts.

Speech impairment resulting from lower motor neuron damage, marked by weakness, breathiness, hypernasality, and imprecise consonants in the affected muscles.

Injury to the non-dominant hemisphere that often leaves language largely intact but disrupts pragmatics, prosody, attention, and awareness of deficits.

The melodic and rhythmic features of speech, including pitch, stress, loudness, and timing, which carry meaning and emotion beyond the words themselves.

The quality of sound shaped by the vocal tract cavities, particularly the balance of oral and nasal airflow, which can be normal, hypernasal, or hyponasal.

Incomplete closure of the soft palate against the pharynx during speech, allowing air to escape through the nose and producing hypernasality and weak consonants.

A fluency disorder characterised by repetitions, prolongations, and blocks that disrupt forward speech flow, often accompanied by tension and avoidance behaviour.

A fluency disorder marked by abnormally rapid or irregular speech rate with excessive disfluencies, poor intelligibility, and often reduced awareness of the problem.

A treatment approach that teaches a new, controlled speaking pattern using slowed rate, gentle onset, light contact, and continuous airflow, then gradually generalises it to natural speech.

Difficulty with swallowing safety or efficiency at any stage, from oral preparation through pharyngeal transit and oesophageal entry, which can lead to aspiration or malnutrition.

Entry of food, liquid, or secretions below the level of the true vocal folds into the airway, which may occur before, during, or after the swallow.

Entry of material into the laryngeal vestibule that does not pass below the true vocal folds; it is shallower and generally less dangerous than aspiration.

Aspiration that produces no coughing or outward sign, common in neurologically impaired clients with reduced laryngeal sensation and therefore only detectable by instrumental assessment.

A dynamic X-ray procedure in which the client swallows barium-coated materials while lateral and anterior views record oral, pharyngeal, and oesophageal events in real time.

A bedside procedure using a flexible endoscope through the nose to view the pharynx and larynx before and after the swallow, detecting residue and penetration or aspiration.

Behavioural testing that establishes hearing thresholds in decibels across frequencies by presenting tones and recording the softest level the client reliably responds to.

An objective measure of middle-ear function that records how easily the eardrum moves as air pressure in the ear canal is varied, helping identify effusion or perforation.

Faint sounds generated by the active outer hair cells of a healthy cochlea and recorded with a probe microphone, used to screen hearing in newborns and difficult-to-test clients.

A graph plotting hearing threshold in decibels against frequency in hertz for each ear, with standard symbols marking air and bone conduction results.

Any system of unaided or aided symbols, devices, or techniques that supplements or replaces natural speech for people with severe communication impairments.

A partner modelling technique in which the communication partner points to symbols on the client's AAC system while speaking, immersing the user in the system's language.

The small set of high-frequency words, such as pronouns, verbs, and prepositions, that make up most everyday utterances and should be prioritised in AAC systems.

A test-teach-retest procedure that measures how much a client improves with structured support, revealing learning potential rather than only current performance.

The clinical process of distinguishing among conditions with overlapping symptoms, such as separating apraxia of speech from dysarthria or language delay from hearing loss.

The degree to which a listener understands a speaker's intended message, often measured by the percentage of words or utterances correctly identified.

Clinical decision-making that integrates the best available research evidence, the clinician's expertise, and the client's values and preferences.

An individualised outcome method that defines several levels of expected progress for each goal and scores actual results against that five-point scale.

A client's voluntary agreement to assessment or treatment after receiving understandable information about purpose, risks, benefits, alternatives, and the right to withdraw.

The professional duty to protect client information from unauthorised disclosure, with limited exceptions such as risk of serious harm or legal requirement.

The range of services a professional is trained and legally permitted to provide, which for speech-language therapists includes communication and swallowing disorders but not medical or surgical treatment.

Directing a client to another professional when needs fall outside the therapist's competence or scope, such as to an ENT physician, neurologist, or audiologist.

Twelve pairs of nerves emerging from the brain that supply the muscles of speech, voice, and swallowing, including the trigeminal, facial, glossopharyngeal, vagus, and hypoglossal nerves.

The four sequential stages of a normal swallow: oral preparatory, oral transit, pharyngeal, and oesophageal, each with distinct motor events and risks of impairment.

A region in the posterior inferior frontal lobe of the dominant hemisphere that supports speech production and motor planning; damage can cause non-fluent aphasia.

A region in the posterior superior temporal lobe of the dominant hemisphere involved in language comprehension; damage can cause fluent aphasia with poor understanding.
