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: An estimation method includes: obtaining a first voice feature group of a plurality of persons who speak a first language; obtaining a second voice feature group of a plurality of persons who speak a second language; obtaining a voice feature of a subject; correcting the voice feature of the subject according to a relationship between the first voice feature group and the second voice feature group; estimating, from the voice feature of the subject that has been corrected, an oral function or a cognitive function of the subject by using an estimation process for an oral function or a cognitive function based on the second language; and outputting a result of estimation of the oral function or the cognitive function of the subject.

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.
