acoustics and mental health
You know how sometimes your various interests end up interacting in surprising ways? Well, I was doing my homework when... (amazing how much of life can start that way) ... I learned that the study of acoustics of speech has been used in an investigation that indicates a possibility of recognizing between depressed versus non-depressed, and perhaps more importantly, depressed from suicidal people (the accuracy wasn't very good for a 100% perfectionist, but hey, it is a start) just by the acoustic properties of their speech, not their actual words. Here is a link that I was able to find thanks to my text book (that I was actually reading!) "Acoustical properties of speech as indicators of depression and suicidal risk" by France et al. It is actually pretty technical, considering I was only partially able to understand it after a month of study in a class on speech acoustics. But I found it exiting to see how mental illness and speech acoustics might relate.
