PROBLEM TO BE SOLVED: To provide an estimation method and an estimation device capable of estimating a state of a subject more accurately than ever before without determining gender.SOLUTION: A plurality of first feature amounts indicating a feeling of a subject are calculated by using data including a voice uttered by the subject. A plurality of second feature amounts indicating a mental state of the subject are calculated by using the plurality of calculated first feature amounts. By weighted-adding the plurality of calculated second feature amounts, a state of the subject is estimated.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】 男女の性別を判定することなく、従来と比べて精度良く被験者の状態を推定できる推定方法および推定装置を提供することを目的とする。【解決手段】 被験者が発話した音声を含むデータを用いて、被験者の感情を示す複数の第１特徴量を算出し、算出した複数の第１特徴量を用いて被験者の精神状態を示す複数の第２特徴量を算出し、算出した複数の第２特徴量を重み付け加算して被験者の状態を推定する。【選択図】 図１
