covert contrast - answerchild produces a measureable, reliable distinction between two
sounds/categories but
-child does not realize contrast in the same way as adults
-adult listeners do not hear the contrast child produces
-Normal adult contrast is 30-100 ms, this tends to be around 15 ms for voiceless

categorical perception - answerMAKES SPEECH IDENTIFICATION SMOOTHER AND
EASIER
we hear speech categories rather than the small acoustic variations across exemplars
of the same phoneme. Used to examine speech discrimination and speech identification
tasks
Allows listeners to ignore irrelevant variations in speech signal while still being sensitive

true - answertrue or false
infants lose the ability to discriminate nonnative contrasts
true - answeradults can relearn nonnative distinctions with training. We can learn to
hear differences in other languages
below - answerchildren with disordered speech production show below or above
average perceptual abilities?
production and perception - answerMost children with SSI show some deficits in both of
these categories
produce - answerthe contrasts that children have difficulty perceiving tend to be the
same contrasts they ____ incorrectly.
speech assessment and interactive learning system (SAILS) - answerpresents recorded
words produced by adult and child speakers. Child points to a picture of the word for a
correct production and the a picture of an x if production is incorrect.
voiced - answerDoes this describe a voiced or voiceless stop?
Low F1 onset, short VOT
voiceless - answerDoes this describe a voiced or voiceless stop?
high F1 onset, long VOT
