Intelligibility has been measured perceptually by two kinds of techniques: _____________ & ____________.
1. Scaling procedures
2. Identification tasks
This intelligibility technique is when the listeners rate the individual's overall speech intelligibility
This intelligibility technique is in which listners transcribe what the speakers says
True or False: Scaling procedures and identification tasks provide little information about the acoustic or phonetic factors responsible for variations intelligibility scores
This theory provides a way of conceptualizing problems of speech production and it includes anything that interferes with the vocal fold vibration.
What is the name for a group of neurological disorders in which the speech musculature is weak, paralyzed, or uncoordinated?
True or False: Duration of both vowels and consonants has been found to be longer and more variable is speakers with different types of dysarthrias.
What is measure of a formant transistion based on the duration and frequency extent of the transition. Measured in Hz/ms.
Acoustic measure of ___________ focus on aspects such as the spectrum of a stop and the duration of frication noise in a fricative.
True or False: Some researchers have found inadequate closure for stops in individuals with Broca's aphasia, MS, and Parkinson's.
Def: Speech that sounds excessively rapid, often occuring in Parkinson's disease.
What is when your articulators fail to achieve the appropriate articulatory target?
True or False: Vowel spaces for hearing-impaired and deaf speakers are often increased, indicating limitations in anterior-posterior and vertical degrees of tongue movements.
False-----> They are often reduced not increased.
Acoustic analysis shows that speakers with __________ hearing impairment produce alveolar and velar stops farther back in the oral cavity than hearing speakers.
Deaf speakers tend to have problems with the ____________ aspects of speech, including inappropriate, excessive, or inadequate variations in fundamental frequency and intensity.
True or False: Visual feedback from acoustic measures such as spectrograms can be use to train speakers to produce more precise articulatory targets.
______________ is a technique for displaying articulatory contacts using electrodes mounted in a psuedopalate.
____________ is a technique used to visualize tongue position within the oral cavity using light-emitting diode photosensors mounted on a pseudopalate
What are two techniques that provide useful clinical information about specific movements and contacts of the tongue and other articulators during speech.
1. palatometry, 2. glossometry
Def: Strategies used to simplify the motoric complexity of phonetic segments.
Phonological process in which a sound with more anterior place of articulation is substutued for one with a more posterior place of articulation is called?
________ is a phonological process in which the final consonant of a word is omitted.
final consonant deletion
TRUE OR FALSE: children
use phonological processes such as fronting and final consonant deletion to simplify the articulatoy gestures for more complex sounds.
False: chilren do
True or False: long-term tracheotomy during infancy will not affect the child's articulation and resonance characteristics.
FALSE: it can affect the child's articulation and resonance characteristics
T or F: Typically, speakers with cleft palate have velopharyngeal problems that contibut to both distortions of resonance and to misarticulations.
What can provide information about a speaker's articulatory movements?
T or F: Measures of duration of vowels and consonants cannot distinguish between normal and dysarthric speakers.
FALSE.... it can!!! woo hoo for measurements!
________ analysis of stops anf fricatives can reveal distinctions in speakers' articulatory positions.
Acoustic analysis shows _______ vowel space in children who received early tracheotomies.
