Abstract
Abstract 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.

A method for electronically detecting human suicidal predisposition by analysis of a series of closely spaced utterances from an emotionally disturbed person actively seeking professional help independently of linguistic content, including the steps of: (a) converting the utterances into an electrical signal having time varying amplitude and frequency which are representative thereof; (b) filtering frequency components of said signal above and below preselected frequencies to obtain a signal within said preselected frequencies; (c) filtering non-repetitive components, having amplitude above about 90% of average amplitude of the signal, out of the signal; (d) filtering repetitive signal components having frequency outside about 90% frequency bandwidth of the signal, out of the signal; (e) identifying as suicidally predisposed a person from whom said vocal utterance emanated if signal amplitude exhibits substantially non-instanteous decays upon conclusion of each utterance, relative to the decays of utterance signals from persons known to be in good mental health.
