Dysphonia and Vocal Tract Discomfort While Working From Home During COVID-19
1Department of Clinical Speech and Language Studies, Trinity College Dublin, Ireland.
Objective:
During COVID-19, government measures to prevent disease spread included advice to work from home. In addition to occupational risk factors, the increased use of telecommunication and changed work environment may contribute to voice and vocal tract discomfort (VTD). This study established the prevalence, incidence, characteristics and impact of self-perceived dysphonia and VTD in those working from home during COVID-19.
Methods:
A cross-sectional, observational study using an online survey recruited 1575 participants. It captured information about dysphonia and VTD presence, onset, and severity. Those with dysphonia completed the voice-related quality of life to measure impact. Regression analyses identified risk factors for voice and vocal tract problems.
Results:
Dysphonia and VTD prevalence rates were 33% and 68%, respectively, incidences were 28% and 50%. Perceived dysphonia severity was mild in 72% of cases. Dry throat was the most common VTD symptom at 66%. Mean voice-related quality of life score was 82.4 (standard deviation ± 13.2). Raising or straining the voice while working predicted new onset dysphonia and VTD. Increasing telecommunication use was associated with worse dysphonia and VTD onset.
Conclusion:
Those working from home have seen a rise in dysphonia and VTD, which were associated with communication modality and change in environment. If home offices become the 'new normal' post-COVID, workplaces should consider voice training for employees to limit potential difficulties.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
