Objectives: The Alexander Technique helps respiration and the projection of voice through changes in the location of the head and relaxation of neck muscles. This study provides objective data on changes in respiration and phonation after training with the Alexander Technique. Methods: A total of 8 students majoring in acting (4 female, 4 male) were selected to participate in a program under the guidance of an Alexander Technique specialist. In order to objectively compare figures, tests were done on respiratory function, aerodynamic analysis, acoustic analysis, and electroglottography (EGG). GRBAS and Korean-Voice Handicap Index (K-VHI) were also taken and evaluated. Results: In the respiratory function test, the FVC, FEV1, and FEV1/FVC had no significant differences. In the aerodynamic analysis, the MPT, GR, and VE significantly increased and the MFR, Psub significantly decreased. In the acoustic analysis, the NHR significantly decreased. In the EGG, the CAx and DQx significantly decreased. The GRBAS evaluation showed that the grade significantly decreased and the K-VHI evaluation showed that the total and the physical area (P) both significantly decreased. Conclusion: This study provides objective and subjective values on voice changes after the Alexander Technique was used for training. The effectiveness of the training technique was verified through objective data showing changes in respiration and phonation.
