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":null,"pages":null},"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}

However, formulating an explicit definition has proven elusive in acoustics and articulation, as diphthongisation is often gradient in these domains. 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":null,"pages":null},"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}

Three experiments were conducted, each examining a different acoustic parameter in the context of code-switching, a dual language paradigm previously shown to enhance cross-linguistic phonetic interference. Bilinguals’ prior experience with code-switching was assessed using the Bilingual Code-Switching Profile. In Experiment 1, Korean–English bilinguals’ productions of F1 and F2 for the code-switched English vowel /æ/ were compared to monolingual (i.e., non-switched) Korean /e/ and English /æ/. 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. Collectively, and suggesting a role for executive control mechanisms at the phonetic level, these findings illustrate that code-switching experience serves to mitigate short-term cross-linguistic interference.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. However, talker- and accent-specific pronunciation features, including suprasegmental characteristics, must be quantified to fully explain intelligibility across talkers and listening conditions.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0095447024000639/pdfft?md5=8f68608c6b33b9f8c629933aabc9e62b&pid=1-s2.0-S0095447024000639-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241716","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}

Motivated by the centrality of accommodation and the perception-production relation to theories of phonetics and sound change, this study tests the hypothesis that individuals who are adept at perceptually retuning for a novel variant will be more accurate imitators of that form. In perceptual eye-tracking and spontaneous imitation ultrasound-imaging tasks, 37 American English participants were exposed to a talker’s novel raised /æ/ before /ɡ/ (<em>bag</em>), and to their familiar unraised /æk/ (<em>back</em>) and /eɪk/ (<em>bake</em>). Consistent with the hypothesis, results showed that the more participants showed perceptual facilitation (i.e., used raised /æ(ɡ)/ to disambiguate <em>back-bag</em> trials), the more they imitated raised /æ(ɡ)/. Perceptual retuning, though, did not predict articulatory restructuring: imitators produced not context-dependent raising, but more general “imitative” raising. For theories of sound change, the findings provide circumscribed support for especially adept perceptual adapters to an innovation having the potential to be strong disseminators of that variant. For theories of accommodation, findings point toward the importance of studying imitation of a targeted variant in the broader context of how talkers and imitators situate that variant in relation to phonetically similar forms.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0095447024000585/pdfft?md5=897dce2fd42f59ca368b5e7dc02d21a1&pid=1-s2.0-S0095447024000585-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142173205","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}

The study explores how the distribution of phrase-level tones and their realization is influenced by focus in different positions of target words with different coda segmental makeups (/pam, pap/). Phrase-initially, focus displays a typical phrase-initial f0 rise for the L and H tones, with the L tone anchored to the focused monosyllabic word and the H tone to the following syllable, accompanied by a tonal expansion. This expansion results from an elevated f0 peak for the H while the L remains unchanged, showing tonal hyperarticulation only in the H tone. Phrase-medially, a similar f0 rise occurs under focus, but without robust tonal expansion. Crucially, the f0 rise is not accompanied by clear temporal or tonal evidence for the creation of a new phrase, demonstrating focus realization without phrasing. Phrase-finally, focus also shows no phrasing evidence. It results in an f0 fall, possibly due to tonal crowding of the L and H tones with the upcoming low boundary tone. However, this fall is distinct from a similar fall under no focus, suggesting a phonetic trace of the focal rise. Both initially and medially, the tonal realization of the f0 rise is affected by the segmental makeup (/pap/ vs. /pam/) only at the microprosodic level while maintaining the tonal targets, even in the face of physically adverse conditions for an f0 rise through the voiceless gap. The findings of the present study illuminate the intricate phonetic details of focus realization with a f0 rise in a language other than the well-studied West Germanic and Romance languages which employ word-level stress. The findings also shed new light on the relationship between focus and prosodic phrasing, implying that focus, previously argued to drive prosodic phrasing in Seoul Korean, is just one of several potentially competing structures that determine a sentence’s phrasing, thereby underscoring the multidimensional nature of prosodic structure.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142149213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
