The purposes of this paper is to study the characteristics of compared to the speakers voice without depression and speakers with depression, and to propose a objective method for the measurement of the therapeutic effects as well as for diagnostics of depression based on the characteristics. The voice samples obtained from 11 female speakers with depression, aged from 20 to 40, diagnosed as having major depressive disorder by an psychiatrist were compared with those from 12 normal controls with matched sex, age, height, weight, education, smoking, and drinking. The voice samples are taken by a portable digital recorder(TASCAM DR-07, Japan) and analysed using the MDVP(Multi-Dimentional Voice Program) software module from CSL(Computerized Speech Lab, kay elemetrics, co, model 4100). The result of the investigation are as following. First, the average speaking fundamental frequency and loudness range of the speakers with depression group was statistically significantly lower than that of the control group. The pitch range of the control group was rather higher than that of the speakers with depression group, but without statistical significance. Overall speech rates have no statistical difference between two groups. Second, the average speaking fundamental frequency and loudness range have statistically significant negative correlation with Beck Depression Inventory, i.e. more severe depression exhibits lower average speaking fundamental frequency and loudness range. Other vocal parameters such as pitch range and overall speech rate have no statistically meaningful correlations with Beck Depression Inventory.
