These two timing mechanisms are particularly interesting to investigate in relation to stuttering, given that CV-timing is especially challenging for PWS and that they exhibit differences in predictive timing related to speech-motor and manual-motor tasks, suggesting that disturbances in inter-gestural coordination and auditory-motor integration may contribute to stuttering. To shed further light on this, we examine CV-timing and predictive timing under different rhythmic conditions.</div><div>Twenty German-speaking adults (10 PWS and 10 PWNS) were recorded using electromagnetic articulography (EMA). Participants produced target words that started with a bilabial onset, followed by a vowel (/a/, /o/, or /u/) and were embedded in a carrier phrase in four different conditions: Unpaced (speaking), Tapping (speaking while concurrently tapping), Metronome (synchronizing speech to a metronome), and Metronome+Tapping (speaking to a metronome while concurrently tapping).</div><div>We found evidence for both CV-timing and predictive timing differences between PWS and PWNS. Our results suggest that in general, PWS time CV gestures closer together. However, CV-timing differences were linked to condition in an unexpected way. As to predictive timing, PWS initiated their speech later to a metronome beat than PWNS but they did not differ when timing speech to their own finger tapping, indicating that motor-pacing may stabilize the speech motor system of PWS. In the Metronome+Tapping condition, the groups appeared to rely on different rhythmic cues. While PWNS timed their speech more towards the metronome beat, PWS synchronized their speech onset closer to the finger tap. We discuss that this difference could result from differences in CV-timing. Furthermore, the potential for future research on the interplay of non-verbal and verbal motor systems and the possible benefit for the stuttering population is discussed.</div></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"112 ","pages":"Article 101432"},"PeriodicalIF":1.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679165","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 a series of three parallel studies, we examined cross-linguistic similarity of Norwegian retroflexes and similar retroflex and non-retroflex sounds by trilingual (L1 Polish, L2 English and L3 Norwegian), bilingual (L1 Polish, L2 English) and Norwegian control (L1 Norwegian, L2 English) listeners. The listeners assessed similarity between the Norwegian and Polish or English sounds primarily based on the place and manner of articulation rather than retroflexion. The results, where condition specifies the presence or absence of agreement in terms of retroflexion and place/manner of articulation, demonstrated that all the two-way interactions: condition:language, condition:group, language:group and the three-way interaction were significant. The study revealed that experience with a given language did not influence similarity ratings in a wholesale manner but rather in a precise manner related to the presence or absence of retroflexion. The results also showed that the perceived cross-linguistic similarity by multilinguals was gradient in nature.

Spontaneous speech from 49 Canadian English-French bilingual speakers was collected from publicly available online data sources. This corpus was processed and a range of acoustic measures of voice quality extracted using an automated pipeline with manual checks. Results do not show strong nor consistent evidence for cross-linguistic differences in creak. Regarding gender, men’s voices are unequivocally creakier, indicated by more unreliable f0 tracks, lower H1*–H2*, lower CPP and lower HNR &lt; 500 Hz. As for age, results generally show more creak for older speakers, CPP and HNR &lt; 500 Hz values increasing with YOB while other acoustic measures show no significant differences, suggesting that these effects are more likely due to vocal aging than sound change in progress. Contrary to popular perception and recent work claiming that young women are leaders in creaky voice use, this study finds that acoustic correlates of creak show the exact opposite: men’s voices are creakier and if anything, younger speakers are less creaky.

Using the incomplete neutralization of the Mandarin 3rd tone sandhi as a test case (T3 + T3 → T2 + T3), we confirmed the presence of this incomplete neutralization with generalized additive modeling (GAMM) and growth curve analysis (GCA). Crucially, we found that the two tones (T2 and T3) became more neutralized when speakers were additionally required to perform a concurrent verbal working memory task while speaking; similar patterns were found when pseudowords were tested, although the overall effects were weaker. Since the concurrent verbal working memory task is expected to add processing load and decrease cascading activation in the spoken word production process, our results suggest that cascading activation, which permits upstream distinctions to surface in downstream acoustics, drives incomplete neutralization. Our study shows how embracing cascading activation can inform the long-standing debate between discrete vs. exemplar representations/operations surrounding incomplete neutralization. How cascading activation is compatible with the core assumptions of generative phonology is also discussed.</div></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"112 ","pages":"Article 101428"},"PeriodicalIF":1.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144605212","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}

We therefore compared 21 L1 English listeners and 21 Mandarin learners of English as they identified reduced targets (e.g., /tuɪnə/ ‘too into’) presented in one of three contexts: Isolation, Textual (orthographic context only), and Auditory (orthography plus the original carrier sentence). Accuracy patterns revealed a graded facilitation hierarchy. For L2 listeners, semantic-syntactic information alone (Textual) boosted recognition relative to Isolation, and adding acoustic context produced a further significant gain. Nevertheless, both effects were smaller for L2 than for L1 listeners, indicating less effective contextual integration in the L2 processing mechanism. The findings refine accounts of reduced-speech perception by showing that L2 listeners can harness acoustic context, but less efficiently than L1 listeners.</div></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"112 ","pages":"Article 101433"},"PeriodicalIF":1.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144632575","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 study adopts an overnight design, using Cantonese contour and level tones contrasting in pitch contour and height, for two perceptual learning experiments conducted separately on Mandarin and English-speaking novice learners of Cantonese. The first experiment found that Mandarin-speaking participants showed a stronger effect of consolidation in novel words contrasting in contour tones than in level tones, thanks to their prior knowledge of contour tones. The consolidation effect was predicted by rough estimates of deep-sleep length. Without prior knowledge of tones, English-speaking L2 learners in the second experiment showed an (unexpected) offline improvement for both contour and level tones.

At the turn of the century, attention shifted from studying <em>when</em> children became attuned to their native language, to asking <em>how</em> children achieved this transformation. Statistical learning became the dominant mechanism to explain language development. But, as researchers pushed the bounds of statistical learning, different questions took center stage: given the complexity of spoken language, how do infants determine which regularities to track? And are the patterns infants track influenced by their unique language learning environment? Inspired by these questions, researchers have shifted to studying acquisition across more diverse contexts, and to using dense corpora and big data approaches to examine how individual differences in children’s input relate to speech perception in the lab. In this paper, we first review this progression, summarizing how the field has arrived at the current state of the art.
