ABSTRACT
The current study aimed to establish rationales for using three different voice therapies (resonant voice, accent method, and tongue-tip trills) by comparing the aerodynamic, and vocal fold closure characteristics under three therapies. A total of 8 male under/graduate students(tenors) participated as subjects. In order to compare aerodynamic characteristics, air flow rates and subglottal pressures were measured using Phonatory function analyzer under three therapy conditions. The characteristics of vocal fold closure patterns also were examined by comparing closed quotients(CQ) measured by Electroglottograph(EGG) under three therapy conditions. However, maximum phonation time (MPT) was measured under only resonant voice and tongue-tip trills using Aerophone II. The results are summarized as follows : 1) CQ, subglottal pressure and MPT decreased significantly under resonant voice as compared with throat voice, but the air flow rate increased significantly under resonant voice. 2) CQ decreased significantly under accent method as compared with throat voice, but both air flow rate and subglottal pressure increased significantly under accent method. 3) Both CQ and MPT decreased significantly under tongue tip trills as compared with throat voice, but air flow rate and subglottal pressure increased significantly under tongue-tip trills. Clinical implications of results were discussed in light of differential effects of three voice therapies.
