Fricatives
Sibiliants are defined as having this
high frication noise intensity
The release of the stop consonant closure interval is roughly
60 to 70 ms after the onset
population typically effected by dysarthria
stroke survivors, TBI survivors, etc.
The property of a sound being perceived as the same regardless of the acoustic conditions
acoustic invariance
Frequencies of waves that have a peak in the wave spectrum where there is maximum energy
peak frequencies
This stands for voice onset time
VOT
Consonant sound that has been studied in speech disorders including dysarthria
fricatives
The period of time during which a valve is closed
closure interval
There are different energy curves within the a spectrum that are emphasized
When does the acoustic theory of speech production depict different frequencies
depends on the location of a constriction in the vocal tract
disruption of what has been hypothesized in several speech disorders
coarticulation
a speech sound intermediate between a vowel and a consonant
semivowel
this shows the range of frequencies important for speech production
the speech banana
These have been generalized to place of articulation of affricates and fricatives
locus equations
this occurs when the muscles you use for speech are weak or you have difficulty controlling them
dysarthria
these are the five features of prosody
intonation, rhythm, stress, pause, and grammatical function
This depends on which fricative is bring used
fricative duration
disruption of coarticulation has been hypothesized in these speech disorders
apraxia, dysarthria, and stuttering
some features of dysarthria include
slurred speech, choppy, mumbled
this surgery is used to remove tongue tissue
glossectomy
