Abstract

Objectives : The purpose of this study is to find out the correlation between the Vocal indicators and the ’Buzhongyiqi-Tang questionnaire’ and the ’Chalder fatigue scale.’
Methods : This study examined the mean value of each factor in the ’Buzhongyiqi-Tang Questionnaire,’ ’Chalder fatigue scale’ and the different voice indicators conducted on 81 healthy adult participants in relation to the results of the /a/ /e/ /i/ /o/ /u/ pronunciation test.
Results : There was significant correlation between the pronunciation of /a/ /e/ /i/ /o/ /u/ vowels’ F0 indexes and ’the Deficiency symptoms of Buzhongyiqi-Tang’. The results of the regression analysis showed the following significant findings for each pronouncing vowels: /i/ as a factor for ’the Deficiency symptoms of Buzhongyiqi-Tang’.; /a/ for ’the Consumptive fever of Buzhongyiqi-Tang’.; /i/ for ’the Vocal inflammation of Buzhongyiqi-Tang.; and /e/ as a factor of ’the Chadler physical fatigue’.
Conclusions : The study showed a negative correlation between the Fundamental Frequency and the mean value of the questionnaire, which could be understood as higher the fatigue level, increased level of vocal vibration and higher pitch tone compared to the less fatigued group. We expect future studies to conduct research on methods to diagnose other illnesses using the vocal indicators based on the correlation between the vocal index and illnesses prescribed under traditional oriental medicine.
