Abstract: It is an object to provide a device for estimating a plurality of mental/nervous system diseases by the voice analysis, the device being capable of estimating either major depression or bipolar disorder. Furthermore, there are provided an estimation device including an extraction means for extracting an acoustic feature amount that is not affected by a location where voices are acquired, and a method for operating the estimation device.

Abstract: An object of the present invention is to provide an information processing apparatus capable of more easily evaluating a depression state. The present invention is an information processing apparatus including: means for inputting voice data uttered by a subject; means for acquiring time-series data of sound pressure in the input voice data; and means for obtaining a Sound Pressure Change acceleration index that is an index based on a force toward a center and a force away from the center of the acquired time-series data of the sound pressure.

Abstract: A medical apparatus for estimating a mental/neurological disease with high precision is provided. This medical apparatus includes a computational processing device, a recording device having an estimation program which causes the computational processing device to execute processing recorded therein, a calculation unit configured to calculate a score of a subject, a detection unit configured to detect a disease whose score exceeds a reference range, and an estimation unit configured to estimate a mental/neurological disease.

Abstract: Provided is a pathological condition analysis system using voice, the pathological condition analysis system allowing anyone to perform measurement and estimate a disease anywhere, in a short time, non-invasively, and without being known to others. A pathological condition analysis system according to the present invention analyzes a pathological condition of a subject, and includes: an input means that acquires voice data of the subject; an estimation means that estimates a disease of the subject based on a voice feature amount extracted from the voice data acquired by the input means; and a display means that displays an estimation result by the estimation means, in which the voice feature amount includes the intensity of voice.
