研究概览
简要总结
To evaluate the efficacy of Semi-occluded vocal tract exercises (SOVTE) in management of voice problems in post-menopausal teachers and to evaluate the knowledge, attitude and practice prevalent among the postmenopausal teachers. Detailed voice analysis will be carried out at the beginning of the intervention (baseline recording), after 1 month and third month of the intervention. The participants will receive training in SOVTE and will be instructed to carry out the exercises twice daily for three months. The outcome measures are: acoustic analysis (fundamental frequency, intensity, cepstral measures, acoustic voice quality index), aerodynamic measures (maximum phonation duration, s/z ratio) and perceptual evaluation.
