Acoustical properties of speech have previously been studied in depression as retarded speech is one of the characteristics often associated with clinical depression. In the present study, we examined the three speech properties namely vocal jitter, power spectral density, and formant structure and studied whether any of these acoustic parameters discriminate clinical depression from normal. The Statistical analysis indicated all parameters studied were significantly different for depressive speech and control group. The implications of these findings are discussed in the background of existing literature.
