In the current study, second dialect acquisition by Midwestern American young adults and its interaction with phonetic reduction processes was examined. Relative to lifetime residents of the Northern and Midland regions of American English, some Northern transplants to the Midland region exhibited second dialect acquisition and others exhibited maintenance of Northern dialect features. All talkers showed phonetic reduction due to lexical frequency, phonological neighborhood density, discourse mention, semantic predictability, and speaking style. These phonetic reduction processes only weakly interacted with dialect variation, such that less phonetic reduction was observed overall when it was potentially in conflict with dialect-specific vowel features. Taken together, the results provide additional evidence for substantial individual variation in second dialect acquisition, but limited evidence of an effect of second dialect acquisition on the interaction between dialect variation and phonetic reduction processes.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"99 ","pages":"Article 101243"},"PeriodicalIF":1.9,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49756402","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}

Previous research has suggested that p-center behavior in languages that lack obstruent clusters, such as Cantonese and Mandarin, will differ from that found in Indo-European languages and others that are typologically different from Chinese languages. The purposes of the current paper are to investigate (1) whether Chinese languages systematically have a different p-center location from that found in previous studies of Indo-European languages, (2) whether vowel onglides are included as part of the syllable rime as claimed in the assumed analysis of Mandarin, and (3) how the alignment of the p-center is influenced by different features of the initial consonant, different features of rime, as well as the speech rates. Six native Mandarin speakers from Taiwan participated in a syllable repetition task with two different speech rates: 60 bpm and 120 bpm. The results indicate that the p-center in Mandarin Chinese is roughly aligned with the acoustic vowel onset, when the syllable does not have an onglide, and the onglide onset, when the syllable has an onglide. The initial consonant manner did not significantly influence onglide or vowel onsets, but the initial consonant acoustic duration, rimes, and speech rates all significantly influenced the vowel onsets as previous p-center studies have found. This appears to differ markedly from the p-center found in a recent study of Cantonese. Various causes for this mismatch are discussed.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"99 ","pages":"Article 101245"},"PeriodicalIF":1.9,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49756404","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 dialects differ with respect to the magnitude of reduction (how changed unstressed vowels are), its generalisation (which vowels are affected), and the resultant neutralisation patterns; overall, reduction is stronger in the eastern variety. A number of long-standing claims about Bulgarian phonology are disproven, notably that there is less reduction in immediately pretonic than in other unstressed syllables, that high vowels are lowered in unstressed position, and that western Bulgarian reduction is necessarily gradient.

First, we investigated the prosodic realisation of information focus and contrastive focus at sentence-initial, -penultimate and -final positions. The analysis of 1980 EA utterances produced by eleven EA native speakers revealed that (1) in focused words, only contrastive focus is realised with expanded excursion size, longer duration, and stronger intensity relative to their neutral focus counterparts, (2) post-focus words have a lower <em>f</em><sub>0</sub> and weaker intensity in both contrastive focus and information focus, and (3) pre-focus words have compressed excursion size and relatively short duration. We then used computational modelling to test how much of the EA intonation could be captured by the PENTA model, with focus-defined functional categories and a number of other, putative categories. PENTAtrainer was trained on syllable-sized multi-functional targets from a subset of the production data. The model then generated <em>f</em><sub>0</sub> contours with the learned targets and imposed them on resynthesised speech for perceptual evaluation. A comparison of the model-generated <em>f</em><sub>0</sub> contours with the natural <em>f</em><sub>0</sub> contours showed that not only focus but also weight, stress, position of word-level stressed syllable and prosodic word are important factors determining the fine details of EA intonation.
