The present study fills this gap by applying a sensorimotor synchronization paradigm to natural speech and studying acoustic landmarks that may serve as perceptual anchors of rhythmic movement in spoken sentences. Five rhythmically relevant types of acoustic landmarks were identified in twenty sentences of English containing syllables with vocalic and non-vocalic nuclei. The landmarks were either manually defined or algorithm-generated and included nucleus onsets, peaks and onsets of inter-syllabic and inter-stress timescales, moments of the fastest energy change (approximating the P-center location), and timepoints of combined pitch and periodic power. Sensorimotor synchronization data from 32 native English participants were examined with regards to the location of an increased synchronization activity in the proximity of the predefined landmarks. The results demonstrated that participants synchronized with syllable-size units regardless of the type of syllable nucleus (vowel or consonant) and that their taps were consistently timed close to nucleus onsets. Hereby, the manually defined nucleus onsets predicted synchronization peaks as well as the algorithm-generated moments of the fastest energy change around nucleus onsets (i.e., a model of the P-center location) did. In contrast, other landmarks did not constitute a stable acoustic anchor of sensorimotor synchronization with English speech. The synchronization performance was not influenced by either acoustic F0-information or by phonological tune specifications. These findings provide new evidence for the proposals that rhythmic attention in natural speech may be locked on to fast spectral changes within a syllable as the smallest structuring unit of prosodic hierarchy.</p></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"100 ","pages":"Article 101263"},"PeriodicalIF":1.9,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49756482","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}

In the perceptual discrimination task, most errors were found for child-produced /ʂ/, and this persisted into the oldest ages. Early acquisition of /ɕ/ has been observed in other languages and may reflect motoric considerations as well as a focus on formant information in child speech perception. Cue weighting appears to change over age in sibilant-specific ways. While all children weight formants highest for /ɕ/, spectral cues appear to be more important for /s/ and /ʂ/, and reliance on formants may decrease with age.

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.

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.
