Self-perception of Voice Handicap in COVID 19 Patients.

Voice abnormalities were reported in patients during the course of COVID-19 infection. This study aims to evaluate the effect of COVID 19 infection on the self-perception of voice handicap in positive COVID 19 patients in addition to investigating the factors that might correlate with voice handicap if present. Voice handicap index-10 was filled in by 200 patients that were confirmed to be COVID 19 positive based on the RT-qPCR and symptomatology of the disease. The result showed that about 65.5% had mild degree of COVID 19 and 27.5% had moderate degree. Dysphonia was reported by 19% of the patients when questioned about voice symptoms. Dysphonia was detected in 35% of them by auditory perceptual assessment. Symptoms of Dyspnea, dysphonia, headache were significantly correlated with total and subtotal scores of Voice handicap index. COVID 19 infection has a negative impact on some of the patients? self- perception of voice handicap on the functional, physical and emotional domains. Age and degree of COVID 19 severity were correlating with the patients? self -perception of voice handicap.

The effect of wearing face masks on voice and intelligibility of speech during the COVID-19 pandemic

Background The study aims at evaluating the effect of wearing face masks on voice and intelligibility of speech in Egyptian working individuals during the COVID-19 pandemic to identify if there are any adverse effects of wearing face masks in the working environment. Materials and methods A cross-section analytical study was conducted on 153 participants. Personal data and data about the nature of their workplaces were collected. The evaluation included a subjective assessment of voice and intelligibility of speech using a specifically designed questionnaire addressing self-perception of voice fatigue, speech unintelligibility, received auditory feedback and breathing difficulty, and objective voice assessment by Computerized Speech Lab, while objective speech unintelligibility assessment by the Arabic Speech Intelligibility Test. Results The study revealed poor workplace acoustics and increased their self-perception of voice fatigue, speech unintelligibility, auditory feedback, and breathing difficulty while wearing masks. Medical professionals showed increased self-perception of speech unintelligibility and the received auditory feedback. No significant difference was found in absolute jitter with and without a face mask. Increasing shimmer and mean fundamental frequency and decreasing noise to harmonic ratio and maximum phonation time were found. The study revealed decreased speech intelligibility especially with the N95 mask. Conclusion Wearing face masks negatively affects communication in the workplace, with poor room acoustics. It affects both speech intelligibility and voice subjectively and objectively. It caused increased self-perception of voice fatigue and changes in objective voice parameters.
