Objective: Medical masks have been shown to significantly influence speech communication in healthy people. The effect of mask-wearing on phonatory capability and daily communication exchanges in patients with voice disorders remains unclear. To evaluate the effect of the medical mask on acoustic parameters in patients with a voice disorder, we measured the voice frequency, quality, and intensity.
Methods: Thirty-three healthy and 44 voice disorder patients were involved in this study, including 27 patients with vocal-fold lesions and 17 with primary functional dysphonia. Perceptual evaluation and acoustic parameters, including F0 (fundamental frequency), jitter, shimmer, and maximum vocal intensity, were analyzed without and with medical masks.
Results: With medical mask-wearing, the maximum vocal intensity significantly decreased in all patients with voice disorders ( < 0.05), especially in patients with lesions of vocal folds ( < 0.05) and functional dysphonia ( < 0.05). The perceptual evaluation roughness scales also increased in patients with lesions of vocal folds ( < 0.05) and functional dysphonia ( < 0.05) with mask-wearing. There were no significant effects of mask-wearing on acoustic parameters for healthy participants.
Conclusions: The intensity was influenced when wearing medical masks in patients with disordered voices. The voice perceptual roughness scales also significantly increased compared to those without medical masks.

Patient Perspectives on Conversational Artificial Intelligence for Atrial Fibrillation Self-Management: Qualitative Analysis.
J Med Internet Res
March 2025
Westmead Applied Research Centre, Faculty of Medicine and Health, The University of Sydney, Westmead, Australia.
Background: Conversational artificial intelligence (AI) allows for engaging interactions, however, its acceptability, barriers, and enablers to support patients with atrial fibrillation (AF) are unknown.
Objective: This work stems from the Coordinating Health care with AI-supported Technology for patients with AF (CHAT-AF) trial and aims to explore patient perspectives on receiving support from a conversational AI support program.
Methods: Patients with AF recruited for a randomized controlled trial who received the intervention were approached for semistructured interviews using purposive sampling.

Laryngopharyngeal reflux disease (LPRD) is characterized by the backflow of gastric contents into the laryngopharynx, distinct from gastroesophageal reflux disease (GERD). Prevalence among otolaryngology patients ranges from 4 to 30% and being the major cause for hoarseness of voice. Common symptoms include hoarseness, chronic coughing, globus sensation, throat clearing and endoscopic evaluation reveals signs like posterior commissure hypertrophy and vocal fold edema.
