The Efficacy of Voice Therapy via Hybrid Group Telepractice Program with Asynchronous Components for Primary School...

To determine the efficacy of a hybrid group telepractice program in voice therapy for primary school teachers.

The participants, consisting of 12 teachers with voice disorders (three males and nine females), participated in 11 sessions of the telepractice program, divided into one training session on vocal hygiene, five practice sessions by themselves, and five group practice sessions in 5weeks. Data on the vocal handicap index (VHI) measure was obtained pre- and post-intervention. The voice analysis included fundamental frequency (local), jitter (local), shimmer (local), harmonic-to-noise ratio (local), and maximum phonation time assessed by Praat software.

The VHI assessment revealed a statistically significant difference (P < 0.05) in the emotional domain. There was no statistically significant difference (P > 0.05) in physical, functional, and total scores. Both males and females had no statistically significant difference (P > 0.05) in mean fundamental frequency. However, there was a statistically significant difference (P < 0.05) in jitter (local), shimmer (local), harmonics-to-noise ratio (local), and the maximum phonation time.

The group telepractice program in voice therapy for primary school teachers was effective. It could be utilized for voice therapy to prevent voice disorder problems in teachers.
