Since Singer's formant is considered to be related to proficiency of classical singing voice, acoustical parameters that represent the relationship between them is required. SFR, Q, and the second convex point represent ratio, sharpness, and height of Singer's formant, respectively. SFR is defined based on the FFT spectrum. Q and the second convex point are defined based on the LPC spectrum. Three analytical questions as follow are examined and shown. (1) Definition of autocorrelation varies sharpness of spectral envelope, and it changes value of Q. (2) The second convex point is in the relation of the logarithm of Q. (3) To keep order of value of Q of various singings, adequate LPC analysis order is 12.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.144 No.12 （2024） 特集：電気・電子・情報関係学会東海支部連合大会本誌掲載ページ: 1197-1208 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/144/12/144_1197/_article/-char/ja/
