1. An apparatus which estimates mental and neurological diseases from voice data of speech of a subject, comprising:
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 which creates a feature quantity from a second acoustic parameter associated with a disease in advance and calculates a score of the subject using the feature quantity and a first acoustic parameter and in which the first acoustic parameter is calculated from the voice data acquired from the subject;
a detection unit which sets a reference range on the basis of the feature quantity and detects a disease whose score exceeds the reference range; and
an estimation unit which estimates the mental and neurological diseases when the detection unit detects one or more diseases,
wherein the apparatus estimates an Alzheimer's disease, Lewy body dementia, a Parkinson's disease, major depression, atypical depression, and a bipolar disorder, and the second acoustic parameter correlates with the mental and neurological diseases.
