The purpose of the study was to examine acoustic, aerodynamic, physiologic, and perceptual characteristics modal vocal fry production. Twenty normal speakers (10 males, 10 females) participated in study. Speech material included four sustained vowels (/i/, /a/, /ae/, /u/), syllable strings /pi/ repetitions produced both registers. Acoustic data (fundamental frequency, jitter, shimmer, signal-to-noise ratio), aerodynamic (airflow air pressure), electroglottographic (EGG) were obtained...

Problem-based learning (PBL) has been shown to be effective for promoting student competencies in self-directed and collaborative learning, critical thinking, self-reflection tackling novel situations. However, the need face-to-face interactions at same place time severely limits potential of traditional PBL. The requirements space meeting a specific location create timetabling difficulties. Such limitations tackled before all potentials PBL can realized. present study aimed designing...

Dysarthria is a motor speech disorder frequently associated with subcortical damage. However, the precise roles of nuclei, particularly basal ganglia and thalamus, in production process remain poorly understood. The present study aimed to better understand their by mapping neuroimaging, behavioral, data obtained from subacute stroke patients lesions. Multivariate lesion-symptom voxel-based morphometry methods were employed correlate lesions thalamus production, emphases on linguistic...

Traditional screening methods for Mild Cognitive Impairment (MCI) face limitations in accessibility and scalability. To address this, we developed validated a speech-based automatic app implementing three speech–language tasks with user-centered design server–client architecture. The integrates automated speech processing SVM classifiers MCI detection. Functionality validation included comparison manual assessment testing real-world settings (n = 12), user engagement evaluated separately...

Abstract In the post-COVID era, face masks have become a part of our daily lives. However, effects these on Mandarin speech production remain unclear. This study aimed to address this research gap by conducting comprehensive investigation impact surgical vowel production. Vowels produced in continuous context were recorded for 61 native Mandarin-speaking adults, both with and without wearing mask. The acoustic parameters associated three corner vowels / i /, u measured. Significant changes...

The present study explored the ways to prepare thickened liquids of different consistencies using lotus root starch (LRS) powder and evaluated their efficacy in treating post-stroke dysphagic patients. Thickened matching four consistency levels advocated by International Dysphagia Diet Standardization Initiative (IDDSI) guidelines were prepared. To assess clinical applicability, 76 patients randomly divided into three groups: a xanthan gum (XG) group (n=26), an LRS control (n=24). All groups...

Childhood autism spectrum disorder (ASD) can easily be misdiagnosed, due to the non-specific social and communicational deficits associated with disorder. The present study aimed profile mental development visual attention towards emotion among preschool children mild or moderate ASD who were attending mainstream kindergartens. A total of 21 (17 boys 4 girls) diagnosed selected from 5178 kindergarten Xi'an city recruited. Another group typical developmental (TD) matched age, gender class...

Background: Laryngopharyngeal reflux (LPR) disease is an extraesophageal manifestation of gastroesophageal (GERD). The impact GERD-related LPR on the psychological well-being and quality life (QOL) in Chinese not known. Aim: To assess QOL patients with disease. Methods: 76 73 healthy subjects were recruited. Psychological was assessed by Hospital Anxiety Depression Score SF-36. Results: 51/76 (67.1%) had LPR. More taken sick leave (36.2 vs. 5.6%, p = 0.001) reported adverse social (60.5...

Background and purpose: Neuroimaging has demonstrated that improved speech outcomes in Parkinson’s Disease (PD) subsequent to behavioural treatment approaches are associated with increased activity the motor pre‐motor cortex. High‐frequency repetitive transcranial magnetic stimulation (rTMS) is capable of modulating cortical been reported have significant benefit general function PD. It possible high‐frequency rTMS may also beneficial on production Methods: (5 Hz) was applied 10 active sham...

In this investigation, a picture-character matching task using the event-related potential (ERP) technique was conducted to identify temporal dynamics of orthographic and semantic activation during Chinese character recognition. The ERP results revealed that impact orthography occurred early long-lasting, whereas effect comparatively late. particular, exhibited larger occipital N170, smaller frontal P200, N400 component for characters sharing information with paired pictures. observed may...

<b><i>Introduction:</i></b> Previous studies reported discrepant vocal qualities associated with different languages. However, possible physical differences speakers of ethnicities were not accounted for. The present study attempted to examine the effect language on one’s voice quality by eliminating potential effects <b><i>Methods:</i></b> Sixteen Chinese and fourteen Americans who proficient in both Mandarin English recruited. They instructed...

Two-minute spontaneous conversational speech of English and Cantonese was obtained from 86 Cantonese-English bilingual children. As a physical measurement the rate vocal fold vibration during production, fundamental frequency (F0) characteristics including mean speaking F0, pitch sigma, minimum maximum F0 values were measured medial 60-second portion samples by using Praat. data productions statistically compared. Significant correlation found for range between English. Results indicated...

The present study determines the acoustical and perceptual differences between alaryngeal laryngeal speakers of Cantonese in production vowels.Formant frequencies (F1 F2) associated with eight vowels [see text] produced by 40 (10 esophageal, 10 tracheoesophageal, pneumatic artificial larynx, electrolaryngeal) were obtained. To assess how formants affect vowel perception, identified 20 naïve listeners, based on which confusion matrices established.Spectral analysis revealed that F1 F2 values...

Mobile devices are increasingly being used by undergraduate students to access online information in the problem-based learning (PBL) process, initially self-directed phase, and more recently within face-to-face tutorials. This qualitative study across three health professional programs semi-structured interviews investigate facilitators' students' perceptions of mobile device usage PBL Transcribed were analyzed thematically, drawing on principles grounded theory. Implications for future...

Previous studies explored the use of noninvasive biomarkers speech and language for detection mild cognitive impairment (MCI). Yet, most them employed single task which might not have adequately captured all aspects their functions.The present study aimed to achieve state-of-the-art accuracy in detecting individuals with MCI using multiple spoken tasks uncover task-specific contributions a tentative interpretation features.Fifty patients clinically diagnosed 60 healthy controls completed...

Fundamental frequency (F₀), F₀ contours, vowel duration, and intensity associated with Cantonese alaryngeal speech, their relation to the perception of meaning were studied. Thirty adult male native speakers participated in study: 10 esophageal, electrolaryngeal, laryngeal speakers. Results indicated that perceptually, listeners able identify what esophageal saying, particularly for words high-level, low-falling high-rising tonal contours. Acoustic analysis speech signals...
