          Abstract

          Studies in Articulatory Phonology ( Browman & Goldstein, 1993) have established that what sounds like insertion of a segment can be a side effect of gestural timing relations. Based on acoustic evidence from a production experiment with six Turkish speakers, I argue that such gestural timing produces non-lexical vowels in complex onsets in Turkish—previously described as harmonizing epenthetic vowels ( Clements & Sezer, 1982, inter alia). Non-lexical vowels occurred in 88.3% of tokens, and usually resembled [ɯ], failing to undergo vowel harmony. Non-lexical vowels are shorter than underlying vowels, and their F1 and F2 values are more affected by the following vowel, suggesting they are more subject to vowel-to-vowel coarticulation. These results support the hypothesis that the inserted acoustic vowels are targetless, created by timing relations between gestures, with the implication that Turkish phonology does not categorically ban complex onsets.

          The relationship between the perception of non-native phonotactics and loanword adaptation

           Lisa Davidson (2007)
          This study examines how phonetic details produced by non-bilingual borrowers (‘disseminators’) are categorised when new words are transmitted to the monolinguals of the borrowing language community (‘recipients’). The stimuli are based on research showing that the schwa inserted by English speakers into non-native clusters (e.g. /zgmo/→[z gmo]) differs acoustically from lexical schwa (e.g. [zgmo]). In , listeners transcribed Cluster (CC), Lexical (CC) and Transitional (C C) stimuli produced by an English speaker. Transcriptions of C C stimuli were split between CC and CVC, and participants wrote C C with a vowel less often than they did CC. demonstrated that listeners had difficulty discriminating between C C and both CC and CC. These findings suggest that C C is acoustically intermediate between clusters and schwas; thus recipients may assign C C token to either of the phonotactic categories CC or CC. The ramifications of these findings for loanwords and the acquisition of phonological contrast are discussed.
