Speech handicap and vocal tract discomfort with different types of face masks in the COVID-19 era

Purpose: Compulsory use of masks is recommended to prevent droplet infection during the COVID-19 pandemic. This can alter optimal communication in daily life. This study compared the self-perceived speech handicap and vocal tract discomfort when wearing and not wearing a face mask and different types of face masks in a healthy population. Methods: This is a cross-sectional study conducted via an online questionnaire. Speech Handicap Index (SHI) and Vocal Tract Discomfort Scale (VTDS) scores were collected via Google forms (Google, Mountain View, California) from 128 healthy Korean populations with and without face masks and different types of face masks. Results: While speaking with a face mask, subjects were identified with a significant lack of air, unclear articulation, and reduced speech intelligibility in a noisy situation. Although total SHI and VTDS scores exhibited slightly higher with a face mask, no significant differences were found between with and without mask conditions. For mask type, individuals who frequently wore KF94 masks subjectively perceived significantly higher speech handicap and vocal tract discomfort than surgical or fabric masks. Conclusions: In the current study, wearing a face mask did not have a significant impact on speech handicap and vocal tract discomfort in a healthy adult population during the CO-VID-19 pandemic period, implying people already adapted to wearing a face mask. In terms of speech problems and frequency, the severity of sensation or symptoms of vocal discomfort significantly differed depending on which face mask type they used. Future research should address self-evaluation of their feeling or experience due to face mask use, considering the elderly and patients with communication disorders who suffer more with communication in daily life. © 2022 The Korean Association of Speech-Language Pathologists.

Effects of Virtual Instruction on Educators' Voices During the COVID-19 Pandemic.

INTRODUCTION: Resulting from the COVID-19 pandemic, professionals in the United States were mandated to work virtually from home to protect the health needs of the population. The shift in setting and ergonomic factors posed a threat to the vocal health of workers, and more specifically, to those whose professions inflict significant vocal load, such as educators. This study compared the symptoms of vocal tract discomfort and self-perceived voice handicap in full-time educators between face-to-face and virtual settings. Additionally, this study sought to identify relationships between specific environmental factors and levels of discomfort. METHODS: A cross-sectional research study was conducted by distributing an online survey to 223 individuals who identified as full-time educators. This survey collected data on vocal tract symptoms during both face-to-face and virtual instruction, environmental factors of virtual work setting, personal vocal health habits, and self-perceived voice handicap in each setting. RESULTS: In this sample population, the shift to a virtual work setting did not result in a significant increase in the number of vocal discomfort symptoms or an increase in vocal handicap. However, environmental factors such as air quality and water intake had the strongest correlation with levels of vocal tract discomfort. CONCLUSION: It is beneficial to provide resources to full-time educators regarding the risk of voice disorders and the impact of environmental factors on vocal health.

Voice Quality and Vocal Tract Discomfort Symptoms in Patients With COVID-19.

INTRODUCTION: Dysphonia and laryngeal problems are some of the manifestations of the COVID-19 pandemic due to respiratory disease as a primary effect of COVID-19. The aim of the present study was to investigate voice quality and vocal tract discomfort symptoms in patients with COVID-19. MATERIALS AND METHODS: Forty-four COVID-19 patients with a mean age of 49.61 ± 16.48 years and 44 healthy subjects with a mean age of 48.52 ± 13.8 years participated in the study. The voice quality of the participants was evaluated using auditory-perceptual evaluation with the Grade, Roughness, Breathiness, Asthenia, and Strain (GRBAS) scale. The vocal tract discomfort symptoms of the participants were assessed using the Persian version of the VTD scale. RESULTS: Patients with COVID-19 had higher scores in all items of the GRBAS, including grade, roughness, breathiness, asthenia, and strain, than healthy subjects, and these differences were statistically significant (P < 0.05). Among the GRBAS parameters, grade had the highest effect size and asthenia had the lowest effect size in both speech tasks. The COVID-19 patients had a greater frequency of vocal tract discomfort symptoms than healthy subjects in all items of the VTDp scale and these differences were statistically significant (P < 0.05) in the following items: burning, tight, dry, pain, sore, irritable, and lump in the throat. The most and the least effect size in frequency of the vocal tract discomfort symptoms were related to dry (d = 1.502) and tickling (d = 0.157), respectively. Also, COVID-19 patients had more significant severity in all items of the VTDp scale except tight and tickling. The most and the least effect size in severity of the vocal tract discomfort symptoms was related to dry (d = 1.416) and tickling (d = 0.152), respectively. CONCLUSION: The present study suggests that COVID-19 patients have more deviations in voice quality than healthy subjects. Moreover, mild vocal tract discomfort is prevalent in patients with COVID-19, and patients have more frequent and severe physical discomforts of the vocal tract than healthy subjects.

Vocal tract discomfort in caregivers for the elderly during an interval of the COVID-19 pandemic.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, professional caregivers caring for the elderly may experience more vocal tract problems in addition to regular high vocal demands while wearing face masks/coverings. METHODS AND PARTICIPANTS: Vocal tract discomfort (VTD) was assessed in 64 caregivers in one home for the elderly (64% participation rate) in June 2020 using the German version of the VTD scale. RESULTS: More than one-half of the participating caregivers experienced VTD, described mostly as dryness, irritability, and tightness. Approximately, 80% reported that sensations were not perceived before enhanced infection prevention standards were implemented. CONCLUSIONS: Among caregivers caring for the elderly during the COVID-19 pandemic, special care should be focused on the voice and vocal tract well-being.
