A method for detecting suicidal predisposition in a person by securing an utterance from the person, identifying the person as being suicidally predisposed if the utterance decays substantially non-instantaneously upon conclusion and identifying the person as being suicidally predisposed if signal amplitude modulation during the utterance is low. Low value of amplitude modulaation (of speech envelope waveform), as well as slow decay at the end of each utterance, are indicators of emotional disturbance, special filtering of repetitives and non-repetitive components enhanced the waveform for consideration.
