Early Detection and Prevention of DepressionMajor depressive disorders (MDD) affect about 4-8% percent of the general population, causing the loss of the ability to work, to have close relationships, and to have a fulfilling life. Available treatments, though effective, have only modest response rates and, most disturbingly, the question of predicting treatment response in the individual patient is not answerable for any of the currently available therapeutic approaches. A considerable number of patients suffer from recurrent episodes of depression so that the early detection of relapse is key for prevention and the development of effective longterm therapies. Speaking Behavior and Voice Sound CharacteristicsDepression significantly reduces the dynamic expressiveness of human voices, thus greatly reducing inter-individual differences. As a direct consequence, the patients' voices become more similar to each other ("depressive voice"): The patients speak in a low voice, slowly, hesitatingly, monotonously, sometimes stuttering, whispering, try several times before they bring out a word, become mute in the middle of a sentence (Kraepelin 1921). During recovery, however, the patients' speaking behavior and voice sound characteristics return to "normal" values. In a series of clinical studies we found a close correlation in two thirds of patients between speech parameters on the one hand, and psychopathology scores on the other. Consequently, speech analyses allow one to monitor the time course of improvement (and possible deterioration) in these patients.
