Individual vocal differences of the coo call in Japanese monkeys

C R Biol. 2004 Feb;327(2):149-57. doi: 10.1016/j.crvi.2003.11.008.

Abstract

We investigated individual vocal characteristics of the coo call in Japanese monkeys. The goal of the study was to determine which parameters are individual discriminators (for individuals of different ages and sexes) and to test whether those differences were similar for individuals of same age and sex. A discriminant analysis realized on eight individuals pointed out that three parameters (call duration, start and end frequencies of the fundamental component) differentiated individuals efficiently and was validated by a second discriminant analysis realized on three same-age females.
