ItemInterpreting rising intonation in Australian English(University of Illinois Press, 2010-01-01)Australian English is referred to widely as a rising variety of English due to the prevalence of rising tunes in interactive discourse. Australian English subjects were required to listen to a series of rising stimuli that varied in terms of pitch level and pitch span and were asked whether they heard a question or statement. The results showed that both rise span and pitch level of the rise elbow influenced the pattern of responses. If both were relatively high, subjects were most likely to interpret the rise as a question, with fewer question responses when the rise elbow was relatively low and the pitch span narrow. The results provide limited evidence for two simple rises in Australian English, but also confirm a high level of phonetic gradience amongst rising tunes in this variety.

ItemThe acoustic characteristics of diphthongs in Indian English(Wiley, 2010-01-01)This paper presents the results of an acoustic analysis of English diphthongs produced by three L1 speakers of Hindi and four L1 speakers of Punjabi. Formant trajectories of rising and falling diphthongs (i.e., vowels where there is a clear rising or falling trajectory through the F1/F2 vowel space) were analysed in a corpus of citation-form words. In line with previous research, the diphthong inventory included six different diphthongs and a long monophthongal vowel [OI] in place of/partial derivative U/in GOAT; however, none of the speakers produced a full set of diphthong vowels. In addition, the/eI/diphthong, as in FACE, and the/U partial derivative/diphthong, as in TOUR, had both monophthongal and diphthongal realizations depending on the speaker. Overall, there was a great deal of variation in diphthong realization across the corpus but L1 appeared to be a relevant factor. Punjabi speakers showed a wider range of phonetic realizations for some of the vowels, and were more likely to produce long monophthongs rather than diphthongs. The results also highlight differences in the phonetic characteristics of several diphthongs between the speakers of two language backgrounds. The results of this study therefore contribute to the debate on the phonemic representation of IE vowels by taking into account different L1 influence (i.e., Hindi or Punjabi).
