A kinematic analysis of new zealand and australian English vowel spaces
نویسندگان
چکیده
The study presents a kinematic and acoustic comparison of the vowel spaces of New Zealand English (NZE) and Australian English (AE). Five talkers of NZE (3F and 2M) and 5 female talkers of AE each produced between 9 15 tokens of monophthongs in HEAD, HID, HAD, HERD. For each token, measurements of lip aperture, lip protrusion, jaw height, and tongue height and backness were made, in addition to formants and vowel duration being calculated. There were three main findings from the study. Firstly the widely held view that the NZE HID vowel may have lowered as it centralised may be incorrect. In this study results suggest that although the NZE vowel is retracted it remains a high front vowel, produced with highly approximated lips. The second result is HERD is lip rounded in both NZE and AE. The final finding is that there is no significant difference in vowel duration between NZE and AE HEAD and HAD, despite NZE HEAD and HAD being phonetically more raised. The implications of these results are discussed.

Acoustic Analysis of Persian EFL Learners' Pronunciation of English Vowels
This paper reports the results of an experimental study on non-native production of English vowels. Two groups of Persian EFL learners varying in language proficiency were tested on their ability to produce the nine plain vowels of American English. Vowel production accuracy was assessed by means of acoustic measurements. Ladefoged and Maddison’s (1996) F1 F2 measurements for American English v...
متن کاملSpeech rates of New Zealand English- and American English-speaking children
Adult speakers of New Zealand English demonstrate faster speaking rates than adult speakers of Australian, American, or British English. Little, however, is known about comparability of speaking rates in children who speak different varieties of English. This study begins to address this need through examining articulation rate and overall speaking rate data for ten New Zealand English-speaking...
متن کاملVowel perception by listeners from different English dialects
Native English listeners from North America rely primarily on changes in formants, not vowel duration, when perceiving the vowel contrast in the minimal pair bit and beat manipulated from a Canadian English sample [5]. In this paper, we evaluated which cue do native English listeners from other regions use when perceiving the same North American vowel contrast. For this purpose, we used the sam...
متن کاملA comparison of acoustic and articulatory methods for analyzing vowel differences across dialects: Data from American and Australian English.
In studies of dialect variation, the articulatory nature of vowels is sometimes inferred from formant values using the following heuristic: F1 is inversely correlated with tongue height and F2 is inversely correlated with tongue backness. This study compared vowel formants and corresponding lingual articulation in two dialects of English, standard North American English, and Australian English....

This study aims to examine acoustic characteristics of English vowels produced by 1 Australian English talker and 3 Japanese learners of English in spontaneous speech. Primary stressed vowels in multi-syllabic words were extracted from five 15minute interview sessions. While there was a considerable overlap between different vowel categories both in native and nonnative vowel spaces, centroids ...
