Voices as Cues to Children’s Needs for Caregiving

“…Sex differences in children's voices can be identified beginning by about 4 years of age, although not always accurately, particularly for girls (e.g., Karlsson & Rothenberg, 1987;Perry et al, 2001;Sergeant et al, 2005). From 7 to 17 years of age, fundamental frequency lowers on average from about 250 Hz to about 200 Hz in females and to about 125 Hz in males, with the greatest decrease occurring in boys at 13-14 years of age (e.g., Balasubramaniam & Nikhita, 2017;Berger et al, 2019;Schneider et al, 2010).…”

“…These differences lead to enormous distinctions in the male and female mutations. Apart from the difference in its dynamics, for girls, voice break happens earlier [26][27][28], starting from the age of 10 and finishing about the age of 14 years, whilst for boys it happens around the age of 12-16 years [29], with some period of voice instability [30,31]. For both genders it results in the enlargement of arytenoids, expansion of the laryngeal muscles and ligaments [32,33], completing of the glottal closure, lengthening of the framework of the larynx, and lengthening and rounding of the vocal folds, 4 which is highly related to changes of the acoustic parameters.…”
