Chapter 7: Clinical Application Evaluation and Treatment of Articulatory and Resonance Disorders

scaling procedures

procedure in which listeners rate an individual's overall speech intelligibility

identification tasks

procedures in which listeners transcribe what a speaker says

pseudopalate

thin acrylic plate custom designed to cover a person's hard palate and upper teeth.

glossometry

technique used to visualize tongue position within the oral cavity using light-emitting diode photo sensors mounted on a pseudopalate

optopalatography

technique that measures the intensity of light reflected from the surface of the tongue and the location and amount of pressure of the contact

dysarthria

term for a group of speech production disorders in which the speech musculature is weak, paralyzed, or uncoordinated

apraxia

difficulty sequencing articulatory movements for speech

slope index

measure of a formant transition based on the duration and frequency extent of the transition. measured in hertz per millisecond (Hz/msec)

accelerated speech

speech that sounds excessively rapid, often occurring in Parkinson's disease

articulatory undershoot

situation in which articulators fail to achieve the appropriate articulatory target

articulatory overshoot

situation in which articulators make contact with excessive force

phonological processes

strategies used to simplify the motoric complexity of phonetic segments

fronting

phonological process in which a sound with a more anterior place of articulation is substituted for one with a more posterior place of articulation

final consonant deletion

phonological process in which the final consonant of a word is omitted
