I happen to be working with several databases of speech recorded with a laryngograph signal (which allows accurate F0 to be estimated). Together they contain 1.75 hours of speech of which half is voiced, pronunced by 38 speakers (19 male, 19 female) of Japanese (30), English (4) and French (4). The data have been carefully labeled with an accurate period estimation method with sub-sample resolution, and the estimates checked visually. A histogram of F0 values with 1/4 semitone bins shows no obvious structure related to the musical scale. A 4-bin histogram of values modulo one semitone is essentially flat. The remarkable statistics of "hand-marked end- and turning points of the contour" are apparently not reflected in raw F0 contours.
