Abstract: An oral function evaluation method includes: obtaining voice data obtained by collecting a voice of an evaluatee uttering a syllable or a fixed phrase that includes (i) two or more morae including a change in a first formant frequency or a change in a second formant frequency or (ii) at least one of a flap, a plosive, a voiceless sound, a double consonant, or a fricative; extracting a prosody feature from the voice data obtained; calculating an estimated value of an oral function of the evaluatee, based on the prosody feature extracted and an oral function estimating equation calculated based on a plurality of training data items; and evaluating an oral function deterioration state of the evaluatee by assessing the estimated value using an oral function evaluation indicator.

Abstract: 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.

Abstract: An estimation device includes: an instructor that instructs a speaker to repetitively utter two syllables containing (i) a sound including a velar plosive in a consonant or a sound including an alveolar fricative in a consonant, and (ii) a sound including an alveolar plosive in a consonant; a voice obtainer that obtains a voice of the speaker; an estimator that analyzes a voice feature of the voice obtained, and estimates an oral function of the speaker based on the voice feature analyzed; and a presenter that presents a condition of the oral function of the speaker which has been estimated.

IPC: A61B5/00
Abstract: 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.

Abstract: A cognitive function evaluation device includes an acquirer that acquires speech data that indicates speech uttered by an evaluatee in response to a task given to the evaluatee; an evaluator that evaluates a cognitive function of the evaluatee by performing a first evaluation based on a proportion of speaking time of the evaluatee in a predetermined period in the speech data acquired by the acquirer and a second evaluation based on a fundamental frequency in the speech data acquired by the acquirer; and an outputter that outputs an evaluation result obtained from the evaluation performed by the evaluator.
