Summary
Background
COVID-19 has transformed face to face teaching in classrooms to online and hybrid
modes. Increased vocal intensity/ pitch to call attention of students and transact
in the online class, inappropriate posture (head, neck & upper trunk) while using
the laptop and other online tools cause vocal loading leading to voice related concerns
in teachers. Tele voice assessment is a feasible alternative means to seek professional
help in the current situation and possibly in the future too. Client-led asynchronous
and clinician-led synchronous voice recordings for clinical vocal measures among school
teachers were compared in this study.
Method
Twenty-five school teachers (21 females & four males) from Chennai consented to the
study. Information of voice use, its impact on the day-to-day situations, self-perception
of vocal fatigue, and their recorded voice sample (phonation & speaking) were obtained
online (asynchronous mode). Within a period of ten days, the clinician-led synchronous
session was planned on a mutually convenient time for obtaining voice samples through
zoom call. The voice samples obtained were compared for clinical measures and perceptual
voice evaluation.
Results
Participants reported of vocal symptoms and increased vocal fatigue scores. The maximum
phonation time values obtained through synchronous mode were lesser when compared
to asynchronous mode. Also, variability was noted in the perceptual vocal measures
of voice samples obtained through synchronous mode. During synchronous voice recording
& evaluation, the background noise, internet stability, audio enhancement feature,
and microphone placement & quality could be monitored, and immediate feedback was
provided. Additionally, the asynchronous recording can be supplemented for synchronous
recording, with clear instructions & demonstration.
Conclusion
This study explored the feasibility of using synchronous and asynchronous voice recording
for voice analysis in school teachers. The findings could serve as a base to understand
the advantages and challenges of using client-led asynchronous and clinician-led synchronous
methods for estimating vocal measures.
