Introduction: This paper aimed at observing the impact of dysphonic voice on children's reception of a linguistic message by evaluating their reaction times (RTs) to instructions given by functional dysphonic and control female schoolteachers (STs).

Methods: French minimal pairs such as /muʃ/ ("mouche" fly) versus /buʃ/ ("bouche" mouth) embedded in a carrier sentence "click on the drawing of…" were produced by two groups of 10 dysphonic and control female ST, matched in age and year of experience. The phonemical contrasts observed are voicing, nasality, consonantal place of articulation, vowel roundedness, and vowel place of articulation. The experimentation was presented in the form of a computer game to children from 7 to 10 years old. Two images illustrating the target words were presented, accompanied by the oral instructions recorded by ST. With a two-button box created for the experiment, children had to click as quickly as possible on the image corresponding to the instruction.

Results: Our results show that the RTs of all children are affected by the ST's dysphonia, regardless of their age and that they have significantly longer RT when discriminating minimal pairs contrasting in voicing when the instruction is given by a dysphonic speaker compared to the same instruction given by a control speaker.

Conclusion: These observations could be explained by the fact that functional dysphonia is associated with improper use of the vocal folds and thus an alteration of voicing.

Introduction: Quality of life and functionality are relevant in an approach based on the biopsychosocial model. Therefore, the objective of this study was to assess the influence of clinical, sociodemographic, and functionality aspects on the quality of life of children and adolescents undergoing speech-language evaluation.

Methods: This is a cross-sectional analytical observational study conducted with 84 Brazilian children and adolescents. The Brazilian Economic Classification Criteria and the Pediatric Quality of Life Inventory 4.0™ were applied, and data were collected on sex, complaints, SPL diagnostic hypothesis, as well as on the Body Functions, Activities and Participation, and Environmental Factors components of the International Classification of Functioning, Disability, and Health (ICF). Factor analysis and structural equation modeling were used for data analysis, with a 5% significance level applied to the final models.

Results: Male sex and clinical-care variables had a direct and negative influence on functionality in the first two models (p < 0.05). Activities and Participation had a positive direct effect on self-reported quality of life (p = 0.031; β = 0.282) and parent/caregiver-reported quality of life (p = 0.003; β = 0.387). Parent-reported quality of life was negatively influenced by complaints of orofacial motricity alterations, while self-reported quality of life was positively influenced by the diagnostic hypothesis of speech disorders.

Conclusion: The results show that sex and clinical-care complaints negatively influenced functionality, while Activities and Participation positively influenced quality of life. The use of structural equation modeling proved to be an important strategy for analyzing ICF and quality of life in SLP practice.

Introduction: Benign and malignant vocal fold lesions (VFLs) are growths that occur on the vocal folds. However, the treatments for these two types of lesions differ significantly. Therefore, it is imperative to use a multidisciplinary approach to properly recognize suspicious lesions. This study aimed to determine the important acoustic characteristics specific to benign and malignant VFLs.

Methods: The acoustic model of voice quality was utilized to measure various acoustic parameters in 157 participants, including individuals with normal, benign, and malignant conditions. The study comprised 62 female and 95 male participants (43 ± 10 years). Voice samples were collected at the Shanghai Eye, Ear, Nose, and Throat Hospital of Fudan University between May 2020 and July 2021. The acoustic variables of the participants were analyzed using Principal Component Analysis (PCA) to present important acoustic characteristics that are specific to normal vocal folds, benign VFLs, and malignant VFLs. The similarities and differences in acoustic factors were also studied for benign conditions including Reinke's edema, polyps, cysts, and leukoplakia.

Results: Using the PCA method, the components that accounted for the variation in the data were identified, highlighting acoustic characteristics in the normal, benign, and malignant groups. The analysis indicated that coefficients of variation in root mean square energy were observed solely within the normal group. Coefficients of variation in pitch (F0) were found to be significant only in benign voices, while higher formant frequencies and their variability were identified as contributors to the acoustic variance within the malignant group. The presence of formant dispersion (FD) as a weighted factor in PCA was exclusively noted in individuals with Reinke's edema. The amplitude ratio between subharmonics and harmonics (SHR) and its coefficients of variation were evident exclusively in the polyps group. In the case of voices with cysts, both pitch (F0) and coefficients of variation for FD were observed to contribute to variations. Additionally, higher formant frequencies and their coefficients of variation played a role in the acoustic variance among voices of patients with leukoplakia.

Conclusion: Experimental evidence demonstrates the utility of the PCA method in the identification of vibrational alterations in the acoustic characteristics of voice affected by lesions. Furthermore, the PCA analysis has highlighted underlying acoustic differences between various conditions such as Reinke's edema, polyps, cysts, and leukoplakia. These findings can be used in the future to develop an automated malignant voice analysis algorithm, which will facilitate timely intervention and management of vocal fold conditions.

Introduction: Behavioral feeding assessment allows for identifying the nature and the cause of abnormal feeding behaviors during mealtime, making prognostic predictions, and creating effective treatment plans. This study aimed to develop and validate an Arabic questionnaire to assess abnormal feeding behaviors among Arabic-speaking children.

Methods: Mansoura Pediatric Eating Assessment Scale (MPEAS) was developed and administered to the parents of 100 Arabic-speaking children aged 1-5, including 50 typically developing children without feeding problems and 50 children with abnormal feeding behaviors. The scale includes 40 items in four subdomains (feeding skills, mealtime circumstances, child behavior, and parent behavior). Scoring was based on a 4-point Likert scale, with lower scores indicating greater impairment. Standardized procedures were used to develop and validate the MPEAS, including the items generation phase, pilot study, validation, and reliability testing.

Results: MPEAS demonstrated excellent validity (face, content, discriminant, predictive, and convergent) and reliability.

Conclusion: MPEAS is a valid, reliable, and easily applicable tool for assessing behavioral feeding problems in Arabic-speaking children. This sensitive and specific tool has the potential to significantly improve the screening and treatment of behavioral feeding problems among Arabic-speaking children, offering hope for better outcomes.

Introduction: Xerostomia, or dry mouth, is a prevalent and distressing oral health condition in older adults that is associated with reduced swallow frequency, thereby increasing the risk of dysphagia and aspiration pneumonia in this cohort. This pseudo-experimental study investigated the association between transcutaneous electrical stimulation (TES) and changes in perceived oral moisture, as well as the function of major and minor salivary glands in two groups of older adults, including those with and without xerostomia.

Methods: Ten older adults with self-reported xerostomia and 7 control participants were exposed to two conditions: no TES and motor TES. TES electrodes were placed on cheeks and submental areas, targeting the parotid, submandibular, and sublingual salivary glands. Participants watched a silent nature movie while receiving continuous TES (only for active TES condition) for 15 min while swallowing sounds were recorded using a microphone attached under the cricoid cartilage. Changes in key outcome measures, including perceived oral moisture (measured by a visual analog scale) along with major and minor salivary glands function (measured by stimulated swallow frequency rate and Periotron) were assessed in response to TES.

Results: The findings indicated that TES increased stimulated swallow frequency rate in both groups (F(1,13) = 9.813, p < 0.008, η_p2 = 0.430). Additionally, the perceived oral moisture measures were only improved for patients with xerostomia (F(1,13) = 5.155, p < 0.041, η_p2 = 0.284). However, no significant changes were noted in minor salivary gland flow rate measures.

Conclusion: These preliminary findings suggest an association between TES and increased objective major salivary gland function in both groups and perceived oral moisture in patients with xerostomia. However, due to the cross-sectional nature of this study, further research involving larger cohorts and controlled designs, and follow up is necessary to understand the mechanisms and potential therapeutic effects of TES on xerostomia.

Introduction: The study aimed to investigate the relationship between pragmatic language skills of children who stutter (CWS) and the frequency of stuttering, with a focus on the development of these skills through peer interaction in the school years. It is well-known that CWS may face social disadvantages at school due to their limited peer interaction, which may pose a risk to the development of their pragmatic language skills.

Method: The study involved 64 CWS aged between 60 and 106 months. Stuttering frequency was determined by analyzing children's spontaneous speech recordings during playtime with their parents. The children's language development was assessed using the Turkish School Age Language Development Assessment Test (TODİL), while speech sound disorders were evaluated using the Turkish Articulation and Phonology Test (SST). Teachers of children whose language and speech sound development were typical were contacted to evaluate the pragmatic language skills of the children using the Pragmatic Language Skills Inventory (PLSI).

Results: The results of the evaluation showed that 51.6% of the children had below-average pragmatic language skills. Additionally, a negative correlation was observed between the frequency of stuttering and PLSI (p < 0.05), suggesting that as the frequency of stuttering increased, pragmatic language skills scores decreased.

Conclusion: CWS may face challenges in communicating effectively, despite their formal language assessment results falling within the normal range. The findings support that pragmatic language skills should be considered when treating stuttering due to their critical role in academic and social outcomes.

Introduction: Thickened liquids are frequently recommended for individuals with swallowing disorders who are at risk of aspiration. However, thickened liquids may be poorly tolerated and result in reduced fluid intake, which may impact performance in a number of areas. The purpose of this study was to examine the possible impact of a thickened liquid regimen on visuospatial skills in young healthy adults.

Methods: Twenty young adults, aged 19-26 years, were included as participants. Baseline data consisting of urine specific gravity (U_SG) measurements as a marker of hydration status and completion of a visuospatial task were obtained prior to initiation of the experimental protocol. Participants in the experimental group followed a thickened liquid protocol, which consisted of drinking nectar-thick liquids for 48 h. Data collection procedures were repeated.

Results: Participants in the experimental group exhibited significantly higher U_SG levels and required more time to complete the visuospatial task post-thickened liquids. No significant change in performance accuracy was found. Participants in the experimental group reported a decrease in fluid intake.

Conclusion: Performance accuracy on a visuospatial task was not significantly impacted by a 48-h period of thickened liquid intake, but time required to complete the task increased and was associated with mild dehydration as indicated by higher U_SG levels.

Introduction: Semantic Feature Analysis (SFA) therapy is a widely used approach for single-word naming treatment in monolingual and bilingual persons with aphasia (BiPWAs). There is evidence that SFA leads to naming improvements in both treated and untreated languages of BiPWAs. However, research on the generalization effects of SFA on narrative production is scarce. This study investigated the within- and cross-language generalization effects of SFA on narrative production and its relationship to naming gains in a group of L1-Russian-L2-Hebrew chronic-stage BiPWAs.

Methods: The study included two groups of BiPWAs. In the experimental group, ten individuals received one or two blocks of SFA, while ten participants who did not receive therapy served as a control group. We compared the changes in narrative production between the experimental and control groups and examined whether the narrative changes in the experimental group were related to naming gains.

Results: The results indicated that SFA generalized to narrative production in the experimental group. Within-language generalization was observed following SFA in L1, while cross-language generalization was found following SFA in both L1 and L2.

Conclusion: Although SFA has the potential to generalize to narrative production in BiPWAs, this effect did not consistently align with the therapy gains in naming. To achieve greater within- and cross-language generalization effects, we recommend providing SFA in the L1 of BiPWAs.

Introduction: Consistency of liquid food plays an important role in managing patients with dysphagia, which can be objectively evaluated by using International Dysphagia Diet Standardisation Initiative (IDDSI) Flow Test and consistometry. The present study established the relationship between IDDSI Flow Test and consistometric measures and examined the measurement limitations of each test associated with thickened liquids prepared using starch-based and xanthan gum-based thickening agents.

Methods: Thirteen thickened liquid samples of consistency ranging from IDDSI level 1 (mildly thick) to level 3 (moderately thick) were prepared using starch-based and xanthan gum-based thickeners. IDDSI Flow Test and consistometric measures were obtained and analyzed using correlation and regression.

Results: A strong correlation was observed between both tests. Regression analyses revealed a linear and a quadratic relationship between IDDSI Flow Test and consistometric measurements, respectively.

Conclusion: Starch-based and xanthan gum-based thickeners exhibited different relationships between IDDSI Flow Test and consistometric measurements. Findings allow easy conversion and adaptation of consistometric measures to the IDDSI framework, which renders the use of consistometry in the clinical settings as a complementary quantitative measurement of liquid consistency to IDDSI Flow Test.

Introduction: Young children with intellectual and developmental disabilities (IDD) who have limited speech and language require access to augmentative and alternative communication (AAC) intervention, including technology and instruction. While research shows that AAC intervention can effectively support communication from children with IDD, research on its impact on school readiness skills is limited.

Methods: Two preschool aged children with IDD participated in this study. Using a single case, multiple baseline across responses design for each participant, this study evaluated the effectiveness of an AAC intervention, including a high-tech AAC with a personalized color photo visual scene display with modeling, time delay, prompting, and social praise. The targeted responses were three questions from the participants' state kindergarten readiness standards, including: "What is your first name?"; "What is your last name?"; and "How old are you?".

Results: In baseline, both participants demonstrated little success communicating answers to questions. During intervention, both participants mastered the school readiness skill of responding accurately and independently to the targeted questions.

Conclusion: The current study shows that with early access to AAC intervention, children with IDD may begin to build communication skills that align with school readiness standards, providing them increased opportunity to participate fully and meaningfully in general education curricula, upon entering kindergarten.
