Compliance, quality of life and quantitative voice quality aspects of hands-free speech

Abstract

After 6 months, 19% of patients used the new ASV on a daily basis (mean 5 h/day), while 57% used it on an irregular basis as an additional rehabilitation tool for special occasions. Two-thirds of the study group indicated that they would continue to use the new ASV after the study period. With respect to the objective parameters, statistically significantly better maximum phonation times and dynamic loudness ranges were observed with the new ASV compared to the Blom-Singer ASV. However, the best results for all the objective parameters were obtained with digital occlusion via the Provox HME.
