    • Application Filed:
      January 07, 2021
    • نبذة مختصرة :
      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.

    • Claim:
      1. An estimation device of a mental/nervous system disease that estimates a mental/nervous system disease by voice analysis, the estimation device discriminating and estimating a major depression and a bipolar disorder, wherein the estimation device comprises: an extractor that extracts, on the basis of an acoustic feature amount (A) that does not have a significant difference due to a recording environment and an acoustic feature amount (B) associated with each disease, an acoustic feature amount (C) common to the acoustic feature amount (A) and the acoustic feature amount (B); a calculator that calculates a prediction value of a disease on the basis of the acoustic feature amount (C); and an estimator that estimates a disease using a prediction value of the disease as an input.
    • Claim:
      2. A method for operating an estimation device, the method comprising: extracting, on the basis of an acoustic feature amount (A) that does not have a significant difference due to a recording environment and an acoustic feature amount (B) associated with each disease, an acoustic feature amount (C) common to the acoustic feature amount (A) and the acoustic feature amount (B) in an extractor of the estimation device; calculating a prediction value of a disease on the basis of the acoustic feature amount in a calculator of the estimation device; and estimating a disease using a prediction value of the disease as an input in an estimator of the estimation device.
