A data-driven modelling-based approach was chosen for this purpose. Midsagittal vocal tract contours from the glottis to the lips for 532 vowels from 41 speakers of three different languages were obtained from MRI data. Corresponding formant values were obtained by acoustic modelling. For each speaker, linear regressions of the contours on the formant values were performed.

Inter-speaker variability was analysed by applying principal components analysis on the components in a second level of modelling. A correlation analysis of the resulting inter-speaker components with morphological features was performed to determine whether a speaker’s strategy could be driven by the morphology.

Results indicate that prosodic word initial position conditions both longer VOT, closure duration, and fewer lenited productions, separately from lexical word position. Moreover, there is an interaction indicating that word initial position leads to longer VOT in unstressed and secondarily stressed syllables, but not in syllables with primary stress.

Within this research, it has been claimed that the phonological status of vowel nasality in a language can determine the temporal extent of phonetic nasal coarticulation. We present a comparative study of anticipatory nasal coarticulation in American English, Northern Metropolitan French, and Standard German. These languages differ in whether nasality is contrastive (French), ostensibly phonologized but not contrastive (American English), or neither (German). We measure nasal intensity during a comparatively large temporal interval preceding a nasal or oral control consonant. In English, coarticulation has the largest temporal domain, whereas in French, anticipatory nasalization is more constrained. German differs from English, but not from French. While these results confirm some of the expected language-specific effects, they underscore that the temporal extent of anticipatory nasal coarticulation can go beyond the preceding vowel if the context does not inhibit velum lowering. For all languages, the onset of coarticulation may considerably precede the pre-nasal vowel in VN sequences, especially so for English. We propose that in English, the pre-nasal vowel has itself become a source of coarticulation, making American English pre-nasal vowel nasality uninformative about coarticulatory nasalization. Degrees of individual variation between the languages align with the phonological or phonologized role of nasalization therein. Overall, our data further add to our understanding of the non-local temporal scope of anticipatory coarticulation and its language-specific expressions.</div></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"107 ","pages":"Article 101365"},"PeriodicalIF":1.9,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142323243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we consider whether diphthong vowels form a coherent phonetic category from the articulatory point of view. We present articulometry and acoustic data from six speakers of Northern Anglo-English producing a full set of phonologically long vowels. We analyse several measures of diphthongisation, all of which suggest that diphthongs are not categorically distinct from long monophthongs. We account for this observation with an Articulatory Phonology/Task Dynamic model in which diphthongs and long monophthongs have a common gestural representation, comprising two articulatory targets in each case, but they differ according to gestural constriction and location of the component gestures. We argue that a two-target representation for all long vowels is independently supported by phonological weight, as well as by the nature of historical diphthongisation and present-day dynamic vowel variation in British English.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"107 ","pages":"Article 101349"},"PeriodicalIF":1.9,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S009544702400055X/pdfft?md5=670338f240cebf09dd5c651ed57b935b&pid=1-s2.0-S009544702400055X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While code-switched English vowels shifted in the direction of monolingual Korean vowels, the results suggest that bilinguals with more code-switching experience exhibited reduced cross-linguistic interference relative to those with less experience. In Experiments 2 and 3, Spanish–English bilinguals’ productions of fricative voicing (Experiment 2) and spirantization of intervocalic voiced stops (Experiment 3) in Spanish and English code-switched tokens were compared to monolingual tokens. Results suggest that participants with greater code-switching experience produced less evidence of cross-linguistic phonetic interference for both fricative voicing and intervocalic spirantization.

To address this gap, intelligibility was measured for 18 talkers -- two from each of three first-language, one bilingual, and five second-language accents -- in quiet and two noise conditions. The relations between two edit distance metrics, which quantify phonetic differences from a reference accent, and intelligibility scores were assessed. Intelligibility was quantified through both fuzzy string matching and percent words correct. Both edit distance metrics were significantly related to intelligibility scores; a heuristic edit distance metric was the best predictor of intelligibility for both scoring methods. Further, there were stronger effects of edit distance as the listening condition increased in difficulty. Talker accent also contributed substantially to intelligibility models, but relations between accent and edit distance did not consistently pattern for the two talkers representing each accent. Frequency of production differences in vowels and consonants was negatively correlated with intelligibility, particularly for consonants. Together, these results suggest that significant amounts of variability in intelligibility across accents can be predicted by phonetic differences from the listener’s home accent.
