The Perception of Correctly and Incorrectly Produced /r/

Abstract

Twenty-six children and adolescents who were unable to produce /r/ correctly were administered a listening task. They were asked to listen to a tape of 200 words containing /r/ in a variety of contexts. Half of the words had been produced by the subjects themselves and half by another speaker who produced /r/ incorrectly. In addition, half of the words from each speaker contained an /r/ that was incorrect whereas the other half contained an /r/ that was edited so that it sounded correct. Subjects made judgments for each word regarding the correctness of the /r/ and the identity of the speaker. Subjects performed significantly more poorly in judging their own incorrect utterances than on any other category of utterance. When judging their own "corrected" utterances, they were more successful at deciding whether the /r/ was correct than in identifying the identity of the speaker. The results provide support for a relationship between speech perception and production in some individuals with a phonological disorder.
