A cognitive function evaluation device includes: an obtainment unit that obtains utterance data indicating a voice of an evaluatee uttering a sentence as instructed; a calculation unit that calculates, from the utterance data obtained by the obtainment unit, a feature based on the utterance data; an evaluation unit that compares the feature calculated by the calculation unit to reference data indicating a relationship between voice data indicating a voice of a person and a cognitive function of the person to evaluate the cognitive function of the evaluatee; and an output unit that outputs the sentence to be uttered by the evaluatee and outputs a result of evaluation by the evaluation unit.

Cognitive function evaluation system, method, and storage medium for dementia by analyzing voice of evaluatee for recognition, remembering or jugment capabilities

A cognitive function evaluation device includes: an instruction unit that instructs quick pronunciation of pseudoword in which a predetermined syllable is repeated; an obtainment unit that obtains voice data indicating a voice of an evaluatee who has received an instruction; a calculation unit that calculates a feature from the voice data obtained by the obtainment unit; an evaluation unit that evaluates a cognitive function of the evaluatee from the feature calculated by the calculation unit; and an output unit that outputs a result of the evaluation by the evaluation unit.

Cognitive function evaluation device, cognitive function evaluation system, cognitive function evaluation method, and non-transitory computer-readable storage medium

A cognitive function evaluation device includes: an obtainment unit configured to obtain speech data indicating speech uttered by a subject; a calculation unit configured to extract a plurality of vowels from the speech data obtained by the obtainment unit, and calculate, for each of the plurality of vowels, a feature value based on a frequency and an amplitude of at least one formant obtained from a spectrum of the vowel; an evaluation unit configured to evaluate a cognitive function of the subject from the feature value calculated by the calculation unit; and an output unit configured to output an evaluation result of the evaluation unit.
