Abstract	Purpose: The present study investigates the perception of vowel nasality in French-speaking children with cochlear implants (CIs; CI group) and children with typical hearing (TH; TH group) aged 4-12 years. By investigating the vocalic nasality feature in French, the study aims to document more broadly the effects of the acoustic limitations of CI in processing segments characterized by acoustic cues that require optimal spectral resolution. The impact of various factors related to children's characteristics, such as chronological/auditory age, age of implantation, and exposure to cued speech, has been studied on performance, and the acoustic characteristics of the stimuli in perceptual tasks have also been investigated. Method: Identification and discrimination tasks involving French nasal and oral vowels were administered to two groups of children: 13 children with CIs (CI group) and 25 children with TH (TH group) divided into three age groups (4-6 years, 7-9 years, and 10-12 years). French nasal vowels were paired with their oral phonological counterpart (phonological pairing) as well as to the closest oral vowel in terms of phonetic proximity (phonetic pairing). Post hoc acoustic analyses of the stimuli were linked to the performance in perception. Results: The results indicate an effect of the auditory status on the performance in the two tasks, with the CI group performing at a lower level than the TH group. However, the scores of the children in the CI group are well above chance level, exceeding 80%. The most common errors in identification were substitutions between nasal vowels and phonetically close oral vowels as well as confusions between the phoneme /u/ and other oral vowels. Phonetic pairs showed lower discrimination performance in the CI group with great variability in the results. Age effects were observed only in TH children for nasal vowel identification, whereas in children with CIs, a positive impact of cued speech practice and early implantation was found. Differential links between performance and acoustic characteristics were found within our groups, suggesting that in children with CIs, selective use of certain acoustic features, presumed to be better transmitted by the implant, leads to better perceptual performance. Conclusions: The study's results reveal specific challenges in children with CIs when processing segments characterized by fine spectral resolution cues. However, the CI children in our study appear to effectively compensate for these difficulties by utilizing various acoustic cues assumed to be well transmitted by the implant, such as cues related to the temporal resolution of stimuli.

Abstract	Objectives: Our aim is to detect early, subclinical speech biomarkers of dysarthria in Parkinson's disease (PD), i.e., systematic atypicalities in speech that remain subtle, are not easily detectible by the clinician, so that the patient is labeled "non-dysarthric." Based on promising exploratory work, we examine here whether vowel articulation, as assessed by three acoustic metrics, can be used as early indicator of speech difficulties associated with Parkinson's disease. Study design: This is a prospective case-control study. Methods: Sixty-three individuals with PD and 35 without PD (healthy controls-HC) participated in this study. Out of 63 PD patients, 43 had been diagnosed with dysarthria (DPD) and 20 had not (NDPD). Sustained vowels were recorded for each speaker and formant frequencies were measured. The analyses focus on three acoustic metrics: individual vowel triangle areas (tVSA), vowel articulation index (VAI) and the Phi index. Results: tVSA were found to be significantly smaller for DPD speakers than for HC. The VAI showed significant differences between these two groups, indicating greater centralization and lower vowel contrasts in the DPD speakers with dysarhtria. In addition, DPD and NDPD speakers had lower Phi values, indicating a lower organization of their vowel system compared to the HC. Results also showed that the VAI index was the most efficient to distinguish between DPD and NDPD whereas the Phi index was the best acoustic metric to discriminate NDPD and HC. Conclusion: This acoustic study identified potential subclinical vowel-related speech biomarkers of dysarthria in speakers with Parkinson's disease who have not been diagnosed with dysarthria.

Abstract	Dans cet article, les résultats d’une étude acoustique sur la production de glides par des locuteurs atteints de la maladie de Parkinson et des locuteurs témoins sont présentés. Notre objectif est d’explorer la dynamique des articulateurs supralaryngés dans la MP, en particulier chez des locuteurs MP non dysarthriques. Nos résultats montrent des différences entre les deux groupes de sujets (locuteurs MP et témoins), en particulier en ce qui concerne l’amplitude des mouvements et la localisation dans le plan F1-F2. Nous notons également que ces différences se produisent en l’absence de dysarthrie, suggérant l’identification de phénomènes infracliniques dans la maladie de Parkinson.

Abstract	Cette étude s’intéresse à l’évolution des capacités de production de la parole dans le vieillissement, dans une perspective lifespan. En effet, en plus de la diminution des capacités de production langagière, l’âge entraîne une réduction des capacités de contrôle moteur de la parole et une dégradation des structures oro-laryngées. Cependant, les effets de l’âge sur les capacités de production de la parole restent peu étudiés, particulièrement en langue française. Dans cette étude, nous nous centrons sur l’analyse du délai d’établissement du voisement (VOT), un paramètre important de la distinction entre les occlusives voisées et non voisées en français, et qui constitue un indice intéressant des capacités de coordination entre les gestes glottiques et supra-glottiques. Dans ce but, nous avons proposé une tâche de répétition de non-mots CVCV, comprenant les six consonnes occlusives du français /p,t,k,b,d,g/ à des participants de 40 à 80 ans, répartis en quatre groupes par tranches d’âges de 10 ans. Les résultats montrent la présence d’une diminution des valeurs de VOT ainsi que des pourcentages de voisement des premières consonnes voisées des non-mots après 60 ans. La présence d’effets délétères de l’âge sur les capacités d’initiation et de maintien du voisement des voisées du français est discutée.

Abstract	Cette étude vise à examiner le développement phonético-phonologique du français et plus précisément la progressive organisation du système vocalique chez des enfants bilingues préscolaires exposés à l’une des trois combinaisons linguistiques suivantes : français-italien, français-arabe et français-mandarin. Les productions orales des enfants ont été recueillies longitudinalement via une tâche de dénomination originale en français. La dominance linguistique des enfants ainsi que leur développement lexical ont été évalués via des questionnaires parentaux. L’évolution de l’organisation du système vocalique a été évaluée via l’indice PHI (Huet & Harmegnies, 2000) permettant de générer une mesure de dispersion des valeurs formantiques dans l’espace vocalique. L’impact de la combinaison et de la dominance linguistiques ainsi que du développement lexical sur l’organisation du système vocalique a été investigué. Les résultats indiquent : (1) un système vocalique initialement mieux organisé chez les bilingues français-italien, (2) une augmentation parallèle de l’organisation du système vocalique et de la compétence lexicale chez les bilingues français-italien et français-arabe et (3), aucun effet de la dominance linguistique. Ces résultats enrichissent les connaissances sur le développement de la parole en français dans des contextes de bilinguisme simultané contrastés.

Abstract	Dans cette communication, nous décrirons une première étude visant à caractériser la perception et la production de consonnes occlusives voisées et non voisées auprès d’enfants présentant une surdité et porteurs d’implant(s) cochléaire(s), et d’enfants normo-entendants. Une tâche de perception catégorielle a ainsi montré des profils différents entre nos deux groupes d’enfants, les enfants implantés présentant des performances dans des tâches d’identification et de discrimination qui différaient de celles de leurs pairs entendants, pouvant suggérer une perception moins catégorielle. Au niveau productif, tandis que les deux groupes d’enfants présentaient des performances équivalentes en termes d’adéquation des productions voisées et non voisées, les analyses acoustiques réalisées sur les productions ont montré des valeurs de Voice Onset Time significativement plus courtes chez les enfants implantés.

Abstract	Anxiety sensitivity (AS), namely the fear of anxiety symptoms, has been described as a precursor of sub-threshold anxiety levels. Sexton et al. (2003) posited that increased AS would arise from an elevated neuroticism and that both would act as vulnerability factors for panic disorder (PD), obsessive-compulsive disorder (OCD), and generalized anxiety disorder (GAD) symptoms. Accordingly, this study aimed to (1) evaluate the applicability of this model to a pediatric population and (2) examine the influences of the other Big-Five personality dimensions on the four lower-order dimensions of AS (cognitive, physical, control, and physical) and on social phobia (SP), separation anxiety disorder (SAD) and depression symptoms. 200 children (104 girls) aged between 8 and 12 years old (mean age = 132.52 months,

Abstract	The aim of the present study is to contribute to the description of the speech production deficits in French-speaking aphasic patients, so as to shed light on their potential phonetic and/or phonological disorders. Acoustic studies of aphasics' speech productions remain relatively infrequent, especially in French, and when entering into the specifics, often lead to inconsistent results. We conducted a multiple-case study on six aphasic patients, four with non-fluent aphasia and two with fluent aphasia. They were administered a variety of language and neuropsychological tasks, then they participated in a customized non-word repetition task. Acoustic analyses of their speech productions were performed, focussing on VOT as the main acoustic correlate of the voicing contrast for oral stops. Other atypicalities in their productions were also classified. Results showed variable and mainly "mixed" phonetic-phonological impairment profiles that differed from the traditional hypotheses made in the literature about the speech deficits to be expected as a function of type of aphasia. Our results support the use of acoustic analyses in order to complete language examination in aphasic patients but also suggest that the frontier between phonological and phonetic impairment is not clear-cut. These outcomes are better accounted for by theories and models postulating close relationships between the phonological and phonetic levels of processing.

Abstract	Introduction: Sixty to 90% of patients with idiopathic Parkinson disease (IPD) developed early dysphonia and subtle speech impairment, which is usually related to orofacial muscular dysfunctions. The aim of this preliminary study is to assess the usefulness of voice quality and orofacial strength (involved in speech) as outcome of levodopa challenge test used for the IPD diagnosis. Material and methods: A total of 20 patients with early IPD were recruited and evaluated for clinical findings (Hoehn and Yahr scale), voice handicap index, maximal phonation time, phonation quotient, percent jitter, percent shimmer, noise-to-harmonic ratio, and orofacial muscular strength (Iowa Oral Performance Instrument) at baseline, throughout the levodopa challenge test and after therapeutic stabilization. Results: The intake of a standardized dose of levodopa (levodopa challenge test) significantly improved phonation quotient and percent shimmer. We did not find similar improvement after medical stabilization of patients (based on levodopa medication) despite an improvement of Hoehn and Yahr mean score. The intake of levodopa significantly improved cheeks and lips strength involved in speech quality both along the challenge test and after the therapeutic stabilization. Conclusions: These preliminary findings support a differential impact of levodopa on voice and speech functions in early diagnosed IPD and a mismatch between the clinical examination, orofacial strength, and voice quality improvements once the patient is medically stabilized.
