Applied Linguistics Research and Methodology

Proceedings from the 2015 CALS conference

Edited By Kristina Cergol Kovacevic and Sanda Lucija Udier

This book offers a selection of sixteen papers presented at the 29th international annual conference of the Croatian Applied Linguistics Society held in 2015. The papers in this book tackle an array of applied linguistics research concerns and provide methodological solutions to many a related problem. The authors’ contributions fall into three main strands of research focus: 1) methodological issues in second language teaching and learning research, 2) experimental research in applied linguistics and 3) spoken and written corpus studies. Almost each individual paper focuses on a different methodological issue in applied linguistics research, treading the path to new related studies.

Ultrasound study: Difference in coarticulation resistance between Croatian fricatives /s/ and /ʃ/

Abstract: This paper presents the results of the ultrasound methodology used in the study of the coarticulatory effect of the neighboring vowel context on the Croatian fricatives /s/ and /ʃ/, for each vowel context separately. It is hypothesized that /s/ will be more variable than /ʃ/ and the vowels will have greater coarticulatory influence on /s/ than on /ʃ/. For both fricatives there will be more influence and variability of the tongue position of the back vowels than the front vowels. The hypotheses are based on the Degree of Articulatory Constraint model (DAC, Recasens, Pallarès and Fontdevila 1997). It is also assumed that the tongue position for fricatives will be more sensitive in carry-over than in anticipatory coarticulation. The speech material was recorded via two simultaneous channels (acoustic and ultrasound) with head stabilization (PHILIP) and speaker stabilization (S.O.S.), and part of the material was obtained from the Croatian ultrasound corpus (HULK) (Carović 2014a). Six speakers (3 male and 3 female) with healthy speaking and hearing statuses were recorded. Ultrasound images were annotated in monosyllabic non-words. The results were presented by means of visual examination and two quantified measures: the tongue Center of Gravity index and the variability index. This kind of basic research can provide important information about the variability of the fricatives /s/ and /ʃ / in Croatian, in diagnostics and in rehabilitation of speech, e.g...
