Abstract
Diphthongs have a dynamic formant structure. Nevertheless, many quantitative studies of diphthongs are based on measurements at only two points, somewhere in the nucleus and somewhere in the glide. The question arises as to whether analyses based on values at only two points provide an adequate understanding of the dynamics of diphthongs. Wieling (2018) mentions the analysis of /aɪ/ raising in Chicago English in Hualde, Luchkina & Eager (2017) as one of several examples of recent studies where potentially interesting patterns may have been missed because of limited sampling of formant values, and proposes using Generalized Additive Mixed Models (GAMM) to allow a more complete understanding of diphthong dynamics. In this paper, we examine the acoustic nature of the (quasi-)phonemic differentiation between two originally allophonic variants of the diphthong /aɪ/ in the US English of Chicago and the surrounding area. We offer an acoustic analysis based on full formant trajectories of diphthongs with data obtained from a group of 53 speakers. The results of a GAMM analysis are then compared with those obtained in Hualde et al. (2017), which considered values at only two points and from a smaller set of speakers (17). We also discuss the main advantages of GAMM analysis over other techniques that have being proposed for the analysis of differences in vowel formant dynamics.
期刊介绍:
The Journal of the International Phonetic Association (JIPA) is a forum for work in the fields of phonetic theory and description. As well as including papers on laboratory phonetics/phonology and related topics, the journal encourages submissions on practical applications of phonetics to areas such as phonetics teaching and speech therapy, as well as the analysis of speech phenomena in relation to computer speech processing. It is especially concerned with the theory behind the International Phonetic Alphabet and discussions of the use of symbols for illustrating the phonetic structures of a wide variety of languages. JIPA now publishes online audio files to supplement written articles Published for the International Phonetic Association
