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":"2025-07-21","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}

The “formant hypothesis” holds that formant frequency locations are the primary encoding of phonetic information. But perceptual experiments have shown that listeners can identify vowels, to a certain extent, even when formant peaks are suppressed. This has given rise to the “whole-spectrum” hypothesis, which describes each vowel segment in terms of a high-dimensional description of its entire spectrum. While the “whole-spectrum” hypothesis better predicts suppressed-formant vowel perception, one advantage of the “formant hypothesis” is that it parameterizes a vowel inventory of a language in terms of featural classes indexed by a few values of formant frequencies. These frequency scales serve to describe a language’s phonological organization and sound change. In this paper, we show that the mel-frequency Cepstral Coefficients (MFCCs), whole-spectrum parameterizations that have been used in speech technology from the 1970’s till today, also have a phonetic interpretation leading to the same featural classes as traditional description. This is despite the fact that for many decades they have been thought to not be interpretable. Our arguments are based on analyses of all vowel data from the TIMIT database, with large amounts of speaker, context, prosodic, and dialectal variability, using information theory, effect-size statistics, and Fourier theory. Our goal is to show that MFCCs can be useful for further developments in the field of acoustic phonetics, because while they extract phonetically-distinctive information from the entire spectrum, they can also further understanding of the linguistic structure of vowel spaces.</div></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"112 ","pages":"Article 101434"},"PeriodicalIF":1.9,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144655552","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":"2025-07-15","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}

Its proper understanding is foundational to phonology and speech production. 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":"2025-07-12","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}

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.

There were no group differences in the acoustics of /k/ in the context of the back vowel, but there were large differences in the other vowel contexts, particularly before the central vowels. We postulate that, whereas the degree of palatalization found in Artà may result from universal coarticulatory principles, palatalization in Manacor results from speaker-controlled phonetic behavior: enhanced coarticulation. Second, we found that in Manacor (but not Artà) /a/ was more fronted when it followed /k/ that when it followed /p/. We suggest that the /a/-fronting pattern found in Manacor results from the influence of its velar-palatalization process and not <em>vice versa</em>.

It traces the physiological and biomechanical foundations of phonetic universals established by 20th-century research while focusing on cross-linguistic variation explored predominantly in 21st-century research. Segmental phonetic universals include <em>the role of the syllable</em> in organizing segments and gestures, <em>intrinsic vowel duration</em> influenced by vowel height, <em>extrinsic vowel duration</em> due to coda voicing, <em>intrinsic and co-intrinsic f0 variation</em> affected by vowel height and onset consonant characteristics, respectively, and <em>place effects on closure duration and VOT</em>. While segmental universals stem from distinct mechanical bases, utterance-level universals emerge from respiratory and articulatory resets at utterance onset, shaping the entire speech production system—a perspective substantiated here based primarily on 21st-century phonetic research. These resets structure prosodic organization, leading to weakening effects at the right edge (e.g., <em>f0 declination, articulatory declination, phrase-final lengthening</em>) and strengthening effects at the left edge (e.g., <em>domain-initial strengthening</em>) and occasionally at the right edge as well (e.g., <em>phrase-final strengthening</em>) when sufficient time permits. Extensive evidence demonstrates that phonetic universals are further shaped by language-specific factors and the interaction between <em>system-oriented</em> and <em>output-oriented</em> constraints. This diversity calls for detailed phonetic descriptions tailored to each language, with phonetic grammar, as proposed here, fine-tuning phonetic realization accordingly. Research in the 21st century has also illuminated that segmental and utterance-level universals, traditionally regarded as distinct, are deeply interconnected, if not inseparable. <em>The Extended Model of Phonetic Grammar</em> is introduced as a framework for mediating this relationship within the phonetics-prosody interface as well as interactions with other higher-order linguistic structures. Furthermore, language variation within phonetic universals suggests that many phonetic processes, once considered automatic, are actively controlled by speakers, reflecting the unique evolutionary pathways of different languages.</div></div>","PeriodicalId":51397,"journal":{"name":"Journal of Phonetics","volume":"111 ","pages":"Article 101426"},"PeriodicalIF":1.9,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144307384","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}

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.
