Effectiveness of Telepractice by Smartphone App Technology in Preventing Voice Problems

Voice disorders in teachers have a significant impact on communication, quality of life, and
economic costs to the healthcare system. We need to advance the prevention of voice disorders
in teachers by testing an online telepractice model with synchronous (in real-time) and
asynchronous (stored and accessed later) methods. The current study will investigate the
effectiveness of the theoretically-driven Global Voice Prevention Model (GVPM) delivered by
two methods; 1) online telepractice (synchronous and asynchronous) and 2) traditional,
in-person for vocally healthy physical education and vocal music student teachers.
Effectiveness of the model will be assessed by voice-related measures captured daily on a
smartphone app during student teaching, matching the asynchronous aspects of the telepractice
model and representing the effects of vocal loading from teaching.
