AI Article Synopsis
- - The study aimed to assess how different factors, like audio equipment and language use, affect vocal habits during online meetings (OMs) in a group of forty participants.
- - Participants experienced various setups, including different audio devices and languages, while their vocal effort and performance were recorded and analyzed.
- - Key findings revealed that speaking in a second language and using a computer's built-in microphone led to increased vocal strain, which could heighten the risk of vocal damage.
Article Abstract
Purpose: To identify factors that influence vocal habits during online meetings (OMs).
Methods: A prospective trial of forty participants without any known hearing or vocal cord disorders. Subjects participated in an OM divided into six randomly ordered sections, with alterations in audio/speaking equipment and language: the computer's speaker-microphone, a single earbud, two-earbuds or headphones; with/without video, native-language-speaking (Hebrew) versus second language-speaking (English). Each section included free speech, sustained phonation, and a standardized passage. Participants ranked their vocal-effort for each section. Three blinded raters independently scored the voice using the GRBAS scale, and acoustic analyses were performed.
Results: No significant difference in self-reported vocal effort was demonstrated between sections. Second-language speaking resulted in significantly increased intensity (p < 0.0001), frequency (p = 0.015), GRBAS (p = 0.008), and strain (p < 0.0001) scores. Using the computer's speaker/microphone resulted in significantly higher strain (p < 0.0001). Using headphones, single or two earbuds resulted in lower intensity and a lower strain score. No differences were detected between OMs with or without video.
Conclusions: Using the computer's microphone/speaker or speaking in a second language during OMs, may result in vocal habits associated with vocal trauma.

Department of Speech and Language Therapy, School of Health Rehabilitation Sciences, University of Patras, Patras, Greece; A' ENT University Clinic, Medical School, National Kapodistreian University of Athens, Athens, Greece. Electronic address:
Objectives: The Singing Voice Handicap Index (SVHI) was culturally adapted and validated in Greek to examine the impacts of voice problems on a singer's everyday life.
Methods: The translated version was administered to 120 singers in total, along with the translated version of the Voice Handicap Index (VHI), a sort voice history questionnaire, two Self-Rating Dysphonia Severity Scales (SRDSSs), and two visual analog scales. A week after the original completion of the Greek version of SVHI, a second copy of the SVHI was administered to 50% of the participants.

Article Synopsis
- The study aimed to assess how effective spirometry is in differentiating between children diagnosed with Induced Laryngeal Obstruction (ILO), chronic non-specific cough, and various degrees of asthma.
- Researchers analyzed medical records of 260 children and found that 97% of those with ILO or chronic cough had normal spirometry results, similar to children with mild asthma.
- The results showed that only children with moderate to severe asthma had significantly lower spirometry values, suggesting that spirometry alone cannot reliably distinguish ILO or chronic cough from mild asthma.
