摘要

The acquisition of rhotic monophthongs(greek source) and diphthongs (greek source)was examined in 3-and 4-year-old children with and without speech sound disorders (SSDs), using both transcription-based and acoustic analyses. African-American (AA) and European-American (EA) participants (n=40) with and without SSD were selected from archival data collected as part of the Memphis Vowel Project. Dialect variation influenced rhotic vowels differently for EA and AA children, thus their data were reported separately. Transcription-based analyses showed wide variation in the accuracy of different rhotic vowels. The most frequent error pattern for children with SSD was Derhoticization to a Back Rounded Vowel (e.g. (greek source)). Rhotic diphthong reduction errors were less frequent; however, Coalesence (greek source) was often observed for (greek source). F2, F3 and F3-F2 spectral movement patterns revealed differences between productions transcribed as correct and incorrect.
