The purpose of this study was to determine whether African American children who delete final consonants mark the presence of those consonants in a manner that might be overlooked in a typical speech evaluation. Using elicited sentences from 10 African American children from 4 to 9 years of age, two studies were conducted. First, vowel length was determined for minimal pairs in which final consonants were deleted. Second, listeners who identified final consonant deletions in the speech of the children were provided training in narrow transcription and reviewed the elicited sentences a second time. Results indicated that the children produced longer vowels preceding "deleted" voiced final consonants, and listeners perceived fewer deletions following training in narrow transcription. The results suggest that these children had knowledge of the final consonants perceived to be deleted. Implications for assessment and intervention are discussed.

Purpose Theoretical models and substantial research have proposed that general auditory sensitivity is a developmental foundation for speech perception and language acquisition. Nonetheless, controversies exist about the effectiveness of general auditory training in improving speech and language skills. This research investigated the relationships among general auditory sensitivity, phonemic speech perception, and word-level speech perception via the examination of pitch and lexical tone perception in children. Method Forty-eight typically developing 4- to 6-year-old Cantonese-speaking children were tested on the discrimination of the pitch patterns of lexical tones in synthetic stimuli, discrimination of naturally produced lexical tones, and identification of lexical tone in familiar words. Results The findings revealed that accurate lexical tone discrimination and identification did not necessarily entail the accurate discrimination of nonlinguistic stimuli that followed the pitch levels and pitch shapes of lexical tones. Although pitch discrimination and tone discrimination abilities were strongly correlated, accuracy in pitch discrimination was lower than that in tone discrimination, and nonspeech pitch discrimination ability did not precede linguistic tone discrimination in the developmental trajectory. Conclusions Contradicting the theoretical models, the findings of this study suggest that general auditory sensitivity and speech perception may not be causally or hierarchically related. The finding that accuracy in pitch discrimination is lower than that in tone discrimination suggests that comparable nonlinguistic auditory perceptual ability may not be necessary for accurate speech perception and language learning. The results cast doubt on the use of nonlinguistic auditory perceptual training to improve children's speech, language, and literacy abilities.
