Question

Inconsistent speech sound errors suggest that Emily presents with
A)A physical abnormality of the vocal tract
B)Underlying phonological knowledge that is intact but use of knowledge that is impaired
C)Impaired underlying phonological knowledge and use of knowledge that is impaired
D)None of the above

Accepted Answer

Inconsistent speech sound errors suggest that there is an underlying phonological knowledge that is intact, but the use of knowledge is impaired. This means that Emily knows the correct speech sounds, but has difficulty using them correctly in her speech. A physical abnormality of the vocal tract would likely result in consistent errors on specific sounds, and impaired underlying phonological knowledge would result in consistent errors across a range of sounds.
