Abstract
Abstract A method for effecting biofeedback regulation of at least one physiological variable characteristic of a subject's emotional state, comprising the steps of monitoring at least one speech parameter characteristic of the subject's emotional state so as to produce an indication signal, and using the indication signal to provide the subject with an indication of the at least one physiological variable. A system permits the method to be carried out in standalone mode or via the telephone line, in which case the indication signal may be derived at a location remote from the subject. Likewise, information relating to the subject's emotional state can be conveyed vocally to a remote party or textually through the Internet, and then processed as required.
