There is provided a cerebrum evaluation device for evaluating the state of the cerebrum of a subject by analyzing a speech signal of the subject by using chaotic signal processing utilizing the periodicity of the signal. The cerebrum evaluation device evaluates the state of the cerebrum according to the speech signal uttered by the subject. The cerebrum evaluation device includes: a statistic information database containing chaotic index values of speech signals of a plurality of subjects; a speech signal acquisition unit for acquiring a speech signal; a chaotic index value calculation unit for calculating a chaotic index value of the speech signal by the chaotic signal processing utilizing the periodicity of the speech signal acquired; an evaluation unit for evaluating the state of the cerebrum of the subject according to the calculated chaotic index value by referencing the statistic information database; and an output unit for outputting the result evaluated by the evaluation unit.

The present invention provides a psychosomatic state determination systemfor the purpose of predicting or determining the psychosomatic state of a subject without imparting any awareness to the subject, comprising a data processing meansfor calculating a psychosomatic state exponent such as Lyapunov exponent from the time series signal of a load value or a barycentric position of the subject, and an evaluation meansfor comparing the temporal tendency of a psychosomatic state exponent calculated in said data processing means with the temporal tendency of a known psychosomatic state exponent corresponding to a psychosomatic state to thereby predict the psychosomatic state of the subject.

Psychosomatic state determination system

A psychosomatic diagnosis system in which evaluation of the psychosomatic condition of a person to be diagnosed is performed automatically and objectively, based on the response by voice with respect to a question and the like asked to the person to be diagnosed. The system includes an index database, a speech processing section for obtaining voice as a speech signal, an analog to digital conversion section for converting the speech signal into a digital speech signal, a data processing section for calculating a human strange attractor by using the chaos theory and storing the human strange attractor in the index database, an attractor evaluation section for performing a quantitative evaluation by using the calculated human strange attractor, and a display section for displaying the evaluation result.
