Background/Objectives: Parkinson’s disease (PD) affects both articulatory and phonatory subsystems, leading to characteristic speech changes known as hypokinetic dysarthria. However, few studies have jointly analyzed these subsystems within the same participants using interpretable deep-learning-based measures. Methods: Speech data from the PC-GITA corpus, including 50 Colombian Spanish speakers with PD and 50 age- and sex-matched healthy controls were analyzed. We combined phonological feature posteriors—probabilistic indices of articulatory constriction derived from the Phonet deep neural network—with harmonics-to-noise ratio (HNR) as a laryngeal measure. Linear mixed-effects models tested how these measures related to disease severity (UPDRS, UPDRS-speech, and Hoehn and Yahr), age, and sex. Results: PD participants showed significantly higher [continuant] posteriors, especially for dental stops, reflecting increased spirantization and articulatory weakening. In contrast, [sonorant] posteriors did not differ from controls, indicating reduced oral constriction without a shift toward more open, approximant-like articulations. HNR was predicted by vowel height and sex but did not distinguish PD from controls, likely reflecting ON-medication recordings. Conclusions: These findings demonstrate that deep-learning-derived articulatory features can capture early, subphonemic weakening in PD speech—particularly for coronal consonants—while single-parameter laryngeal indices such as HNR are less sensitive under medicated conditions. By linking spectral energy patterns to interpretable phonological categories, this approach provides a transparent framework for detecting subtle articulatory deficits and developing feature-level biomarkers of PD progression.

This chapter will focus on the presence of musical notation in literary texts, their aesthetic, (inter-)medial presence and potentialities, in paradigmatic Modern short stories such as Katherine Mansfield’s “The Wind Blows” (1915), Virginia Woolf’s “The String Quartet” (1921) and Vladimir Nabokov’s “Music” (1932). What these stories share is a perception of music as sonorous moving forms, symbolic imagery or seemingly ‘dancing’ musical notation on the page. In introducing the term notational ekphrasis, I wish to differentiate these phenomena as overt and covert for the larger theory of intermediality. In doing so, I will show how these narratives negotiate musical notation, writing and iconicity. Full article

Children’s consonant cluster productions in typical and atypical phonological development were investigated for different languages reporting developmental productions that are universal, language-specific, and/or child-specific. These patterns are often interpreted considering sonority hierarchy effects. Quantitative norms on developmental cluster productions are less prevalent in the literature cross-linguistically, as are investigations on the development of less frequent cluster types in the world’s languages, like those involving falling and level sonority two-member onsets. Our study contributes to these investigations, focusing on Greek-specific onsets: falling sonority obstruents [ft, xt], level sonority obstruents [fθ, fç, ðʝ, xθ, ɣð], and level sonority nasals [mɲ]. We present cross-sectional, longitudinal data from 90 monolingual children, aged 2;0–4;0, based on the word elicitation task, Phonological Assessment for Greek (PAel). As only [ft] 89%, [fç] 80%, [mɲ] 88% are acquired by 3;6–4;0, the data provide evidence that [ft, xt, fθ, xθ, ɣð] reduce to C2, [mɲ] reduces to C1, and [fç], [ðʝ] show the most variability in reduction/simplification patterns. Reduction patterns largely reflect individual cluster acquisition paths longitudinally; the relative reduction to a member changes with age, but the preference to the member does not, except for [ðʝ]. The data facilitate the establishment of quantitative markers for cluster development and qualitative interpretations in terms of featural and structural prominence, including a veiled sonority effect not previously reported in the literature.

The present paper investigates the link between perception and production in the laryngeal phonology of multilingual speakers, focusing on non-contrastive segments and the dynamic aspect of these processes. Fourteen L1 Hungarian, L2 English, and L3 Spanish advanced learners took part in the experiments. The production experiments examined the aspiration of voiceless stops in word-initial position, regressive voicing assimilation, and pre-sonorant voicing; the latter two processes were analyzed both word-internally and across word boundaries. The perception experiments aimed to find out whether learners notice the phonetic outputs of these processes and regard them as linguistically relevant. Our results showed that perception and production are not aligned. Accurate production is dependent on accurate perception, but accurate perception is not necessarily transferred into production. In laryngeal postlexical processes, the native language seems to play the primary role even for highly competent learners, but markedness might be relevant too. The novel findings of this study are that phonetic category formation seems to be easier than the acquisition of dynamic allophonic alternations and that metaphonological awareness is correlated with perception but not with production.

Objective: This study aimed to evaluate lenition, a phonological process involving consonant weakening, as a diagnostic marker for differentiating Parkinson’s Disease (PD) from Atypical Parkinsonism (APD). Early diagnosis is critical for optimizing treatment outcomes, and lenition patterns in stop consonants may provide valuable insights into the distinct motor speech impairments associated with these conditions. Methods: Using Phonet, a machine learning model trained to detect phonological features, we analyzed the posterior probabilities of continuant and sonorant features from the speech of 142 participants (108 PD, 34 APD). Lenition was quantified based on deviations from expected values, and linear mixed-effects models were applied to compare phonological patterns between the two groups. Results: PD patients exhibited more stable articulatory patterns, particularly in preserving the contrast between voiced and voiceless stops. In contrast, APD patients showed greater lenition, particularly in voiceless stops, coupled with increased articulatory variability, reflecting a more generalized motor deficit. Conclusions: Lenition patterns, especially in voiceless stops, may serve as non-invasive markers for distinguishing PD from APD. These findings suggest potential applications in early diagnosis and tracking disease progression. Future research should expand the analysis to include a broader range of phonological features and contexts to improve diagnostic accuracy. Full article

The modulation of vocal elements, such as pitch, loudness, and duration, plays a crucial role in conveying both linguistic information and the speaker’s emotional state. While acoustic features like fundamental frequency (F0) variability have been widely studied in emotional speech analysis, accurately classifying emotion remains challenging due to the complex and dynamic nature of vocal expressions. Traditional analytical methods often oversimplify these dynamics, potentially overlooking intricate patterns indicative of specific emotions. This study examines the influences of emotion and temporal variation on dynamic F0 contours in the analytical framework, utilizing a dataset valuable for its diverse emotional expressions. However, the analysis is constrained by the limited variety of sentences employed, which may affect the generalizability of the findings to broader linguistic contexts. We utilized the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS), focusing on eight distinct emotional states performed by 24 professional actors. Sonorant segments were extracted, and F0 measurements were converted into semitones relative to a 100 Hz baseline to standardize pitch variations. By employing Generalized Additive Mixed Models (GAMMs), we modeled non-linear trajectories of F0 contours over time, accounting for fixed effects (emotions) and random effects (individual speaker variability). Our analysis revealed that incorporating emotion-specific, non-linear time effects and individual speaker differences significantly improved the model’s explanatory power, ultimately explaining up to 66.5% of the variance in the F0. The inclusion of random smooths for time within speakers captured individual temporal modulation patterns, providing a more accurate representation of emotional speech dynamics. The results demonstrate that dynamic modeling of F0 contours using GAMMs enhances the accuracy of emotion classification in speech. This approach captures the nuanced pitch patterns associated with different emotions and accounts for individual variability among speakers. The findings contribute to a deeper understanding of the vocal expression of emotions and offer valuable insights for advancing speech emotion recognition systems. Full article

This paper discusses the renewal of the conception of film sound and music following the technological advances of the late 1970s. It analyses the ways in which film sound and music freed themselves from traditional uses and became elements to be designed creatively. The soundtrack composed by Vangelis for Blade Runner (1982) is exceptional in this regard: produced in parallel to the editing of the film, it forged an intimate connection between sound and image. Through the method of reduced listening put forward by Michel Chion in Audio-Vision (2019), this paper scrutinizes the specific ways in which sound shapes the perception of the image and narrative in Blade Runner. The first part of this paper analyses how sounds come to replace music to characterize moods and atmospheres. Ambient sounds create a concrete, sonically dense diegetic world, while music is associated with an abstract, extra-diegetic world where spectators are designated judges. This contrast is thematically relevant and delineates the struggle between humans and replicants; sound and music are used for their metaphorical implications rather than in an effort for realism. The second part discusses the agency of characters through the sonorousness of their voices and bodies. Intonations, pronunciation, and acousmatic sounds anchor characters’ natures as humans or replicants to their bodies. Yet, these bodies are revealed to be mere vessels awaiting definition; in the third part, we explore how sound is used to craft synaesthetic depictions of characters, revealing their existence beyond the human/replicant divide.

Objective: This study investigated the degrees of lenition, or consonantal weakening, in the production of Spanish stop consonants by native English speakers during a study abroad (SA) program. Lenition is a key phonological process in Spanish, where voiced stops (/b/, /d/, /ɡ/) typically weaken to fricatives or approximants in specific phonetic environments. For L2 learners, mastering this subtle process is essential for achieving native-like pronunciation. Methods: To assess the learners’ progress in acquiring lenition, we employed Phonet, a deep learning model. Unlike traditional quantitative acoustic methods that focus on measuring the physical properties of speech sounds, Phonet utilizes recurrent neural networks to predict the posterior probabilities of phonological features, particularly sonorant and continuant characteristics, which are central to the lenition process. Results: The results indicated that while learners showed progress in producing the fricative-like variants of lenition during the SA program and understood how to produce lenition in appropriate contexts, the retention of these phonological gains was not sustained after their return. Additionally, unlike native speakers, the learners never fully achieved the approximant-like realization of lenition. Conclusions: These findings underscore the need for sustained exposure and practice beyond the SA experience to ensure the long-term retention of L2 phonological patterns. While SA programs offer valuable opportunities for enhancing L2 pronunciation, they should be supplemented with ongoing support to consolidate and extend the gains achieved during the immersive experience.

The default mode network (DMN) is a complex network that plays a significant and active role during naturalistic stimulation. Previous studies that have used naturalistic stimuli, such as real-life stories or silent or sonorous films, have found that the information processing involved a complex hierarchical set of brain regions, including the DMN nodes. The DMN is not involved in low-level features and is only associated with high-level content-related incoming information. The human sexual experience involves a complex set of processes related to both external context and inner processes. Since the DMN plays an active role in the integration of naturalistic stimuli and aesthetic perception with beliefs, thoughts, and episodic autobiographical memories, we aimed at quantifying the involvement of the nodes of the DMN during visual sexual stimulation. After a systematic search in the principal electronic databases, we selected 83 fMRI studies, and an ALE meta-analysis was calculated. We performed conjunction analyses to assess differences in the DMN related to stimulus modalities, sex differences, and sexual orientation. The results show that sexual stimulation alters the topography of the DMN and highlights the DMN’s active role in the integration of sexual stimuli with sexual schemas and beliefs. Full article

Livelihood loss and lower income because of peatland mismanagement are crucial issues that must be resolved in peatland areas. Although many studies have assessed farmers’ livelihoods and income enhancement, progress in addressing these problems remains inadequate. To address this issue, this study aimed to analyze various existing alternative livelihoods in the peatland community in Ogan Komering Ilir District, South Sumatra Province, Indonesia, and analyze scenarios for creating livelihoods and increasing people’s incomes through changes in peat ecosystem management and peatland restoration programs. This study used a survey method conducted in South Sumatra Province’s OKI District, one of the four priority peat-restoration districts in the province. We used three sampling stages, while descriptive, tabulated, and mathematical methods were used for analysis. We analyzed the feasibility of livelihoods that used benefit-cost analysis. The results showed that Sonor cultivation of paddies and catching fish in Rawang (swamp) were the livelihoods of farmers in peatlands. The community has also been processing peatland commodities into other products, such as Purun woven, and Gula Puan (buffalo milk processing). Several alternative livelihood scenarios that are financially profitable and can be developed include salted and smoked fish, Purun woven handicrafts, paludiculture, and agrosilvofishery, which can provide farmers with short-, medium-, and long-term income opportunities. This study can contribute to policymaking by fully considering the role of peat resources in rural livelihoods. Full article

As the need for sustainable use peatlands increases, the aim of this study is to identify ways to increase the application of agrosilvofishery as an alternative to the traditional sonor system. Herein, the researchers investigate the perception of peatland degradation and the willingness to participate in agrosilvofishery among peatland residents. The researchers interviewed 228 households in Perigi Village, South Sumatra, Indonesia, and surveyed 137 peatland owners. Logistic regression analysis revealed a positive correlation between the willingness to participate in agrosilvofishery and household expenses, plans to improve peatland productivity, and knowledge regarding mixed farming in farmer and non-farmer groups. Willingness to provide labor for agrosilvofishery was positively correlated with household expenses and experience with farmer organizations. For both groups, the willingness to participate had a more substantial impact on the willingness to contribute to the agrosilvofishery financially than on the willingness to provide labor. It is imperative to consider various educational, institutional, research, and cultural factors that enable peatland agrosilvofisheries to contribute to the income and livelihood of the residents of Perigi Village. Institutional arrangements should be established, including initial capital support for restoration projects and a system involving the entire village community. This study can contribute to offering guidance for implementing agrosilvofisheries and enhance the practicality of field applications for peatland restoration. Full article

The present study investigated whether L1 and L2 Spanish speakers show sensitivity to matching/mismatching syllable structure and consonant sonority in lexical segmentation in Spanish. A total of 81 English–Spanish learners and 72 Spanish–English learners completed a fragment-monitoring task. They listened to lists of Spanish words as they saw a CV or CVC syllable (e.g., “pa” or “pal”) and pressed a button when the word began with the syllable shown on the screen. The task manipulated syllable structure (CV or CVC) and consonant sonority (fricative, nasal, or liquid) of target syllables and carrier words. Target syllables either matched or did not match the structure of the first syllable in target carrier words (e.g., “pa—pa.lo.ma”; “pa—pal.me.ra”). The results showed that consonant sonority modulated sensitivity to syllable structure in both groups of participants. Spanish–English learners responded faster to matching syllable structure in words that had a fricative or a nasal as the second consonant, and English–Spanish learners responded faster only with a fricative consonant. Higher L2 Spanish proficiency correlated with faster target-syllable identification, but sensitivity to matching/mismatching structure did not vary as a function of proficiency. The study highlights the influence of phonetic factors in the development of L2 lexical segmentation routines. Full article

Luigi Russolo’s Intonarumori together with his manifesto L’arte dei rumori (1913) marked a break with the art of clear signification. From here on, noise and dispersed sounds replaced the concept of music reverberating the harmony of the spheres by propelling the quandaries of immanence contingent on palpable resonance performing the differential relational manner of heterogeneous existence. This somatic turn is central to Jean-Luc Nancy’s Listening, where he proposes listening as a tangible fundamental resonance rumbling the corpse sonore. This paper elaborates on the move from the art of music to the plurality of rhythmic worlds. Nancy’s proposition of sonorous existence demonstrates two movements, one that retreats from hearing the Pythagorean musical-arithmetical cosmos exhibited in Robert Fludd’s Monochord, the other plays the singular plural pulsations of dispersed creation performed by Michael Snow’s Tap.

Propelled by existing research on stop consonant variability in Spanish, this pilot study provides a preliminary acoustic analysis of stop consonant lenition exhibited by speakers of six different varieties of Spanish in Latin America and Spain to explore the gradient acoustic variability in the production of /ptk/ and /bdɡ/ among speakers of different Spanish varieties. Using the acoustic correlate of relative intensity, this analysis considers the effect of various linguistic factors (phoneme, lexical stress, point of articulation, sonority) as well as the extralinguistic factor of Spanish variety on the production of stop consonants in initial, intervocalic position. Results display a higher degree of weakening among speakers of Peninsular and Insular varieties of Spanish compared with those of Latin-American varieties such as Colombian, Mexican, and Peruvian. These exploratory data support the gradient nature of consonant lenition and provide a baseline for future research on stop consonant variability across the Spanish-speaking world. Full article

In this study, we aimed to deepen the understanding of the circumstances under which crosslinguistic influence occurs, by focusing on the acquisition of the Dutch plural by two- and three-year old children who attend bilingual Dutch-English daycare. In doing so, we explored the roles of variability, overlap and language dominance as these are all factors that have been linked to the occurrence of crosslinguistic influence in studies on bilingual language acquisition and language contact. We investigated the expectation that young children who are exposed to English might show a stronger preference for -s pluralization in Dutch, because of the partial overlap in Dutch and English pluralization. In total, a group of 95 children that grew up with only Dutch and/or English at home and attended bilingual (Dutch-English) daycare (51 females, 44 males, mean age = 3;6 years) participated in an elicited production task. Results showed that no clear-cut evidence for unidirectional crosslinguistic influence from English to Dutch could be found in the form of -s overgeneralizations. However, we did find evidence for the role of variability in this domain of language, since children made more overgeneralizations when rhyme and sonorancy contradicted. Also, English exposure seemed to facilitate correct production of the -s affix, and children who overgeneralized the -s affix were mostly children that were exposed to the English language at home, suggesting that language dominance does play a role in preference for the -s affix.
