Abstract

Arabic emphatic consonants are primarily cued by coarticulatory effects on adjacent vowels, yet little is known about how these effects unfold across different vowels. This study examined the temporal dynamics of emphatic coarticulation in Saudi Hijazi Arabic across three vowel contexts (/iː/, /aː/, /uː/) and two manners of articulation (stops, fricatives). The plain-emphatic contrast was robust across vowels and manners of articulation for F2 and less consistent for F1. The F2 contrast persisted longest in /aː/, followed by /uː/ and /iː/, with estimated differences also largest in /aː/. Vowel-dependent temporal dynamics further our understanding of emphatic coarticulation beyond static measurements.

Acoustic analysis of voice gender in Hijazi Arabic

Knowledge about vowel-related acoustic features and their role in gendered speech remains limited, especially in Hijazi Arabic. While dynamic analysis, particularly vowel-inherent spectral change, offers advantages, Arabic vowel studies have focused on single-point acoustic features. This study analyzes Hijazi Arabic v...

ENGLISH VOWEL CONTRASTS IN CANTONESE L1 LEARNERS: ACOUSTIC SEPARATION AND PROCESSING STRATEGIES

Cantonese first-language learners of English often struggle with vowel contrasts not clearly represented in Cantonese. This exploratory mixed-methods study investigated the production and self-reported processing of three English contrasts: /iː/–/ɪ/, /æ/–/ɛ/, and /ʌ/–/ɑː/. Acoustic data from seven speakers were analyse...

The Pronunciation of the Schwa An Acoustic Analysis of Gender Inclusivity in Spoken Italian

In Italian, the schwa has spread to encode gender beyond the binary, yet /ə/ is not part of the standard phonemic inventory. This study addresses the recurring unpronounceability argument by focusing on acoustic vowel distance. Drawing on 10 interpreters’ production of words containing the mid-central vowel (/ə/; n=205...

Acoustic correlates of Albanian word stress in relation to the Balkan Slavic environment

This article investigates the acoustic correlates of word stress in Kosovo Standard Albanian through two experimental paradigms: a study of minimal pairs (seven speakers) and a continuous text analysis. The research examines intensity, fundamental frequency (F0), and vowel duration. The results demonstrate that intensi...

Correlations and Functional Explanations in Laryngeal Phonetics and Phonology: Evidence from New Zealand English

Varieties of English differ in (i) the amount of aspiration/voicing in plosives, traditionally measured in Voice Onset Time (VOT), and (ii) the degree of vowel clipping before fortis consonants (the Voicing Effect). The two seem to correlate with each other, with a possible functional explanation, but they also interac...
