The pitch characteristics of the adolescent male voice¹

Pitch and Quality Characteristics of Mutational Voice Disorders before and after Therapy

“…In the present study the pretherapy speaking X F (1 o f 221 Hz calculated as a mean for 10 o f the 13 men was lowered to a X F () o f 119 Hz after thera py. Curry [1940] reported a difference o f approximately 1 octave between the pitch levels of 14-and 18-year-old subject groups, the respective values being 245.5 and 137.1 Hz. In their study of 25 Danish choir boys with no special voice problems.…”

“…To my knowl edge, there are three reports based on case histories [Greene, 1921;Curry, 1940;Ka plan, 1982]. These reports will be com mented on in the ' Discussion'.…”

Speaking Fundamental Frequency Characteristics of Normal Swedish Subjects Obtained by Glottal Frequency Analysis

“…1981], speaking foreign languages [Hanley ct al., 1966;, or mutational voice [Curry, 1940;Hollien and Malcik, 1967;Hollien and Paul, 1969;Duffy, 1970].…”

Effect of Ethnicity on the Age of Onset of the Male Voice Change

“…Most literature referring to ethnic groups has utilized the term White rather than Caucasian, especially in regards to the topic of male puberty or the adolescent male voice (Curry, 1940;Herman-Giddens, Wang, & Koch, 2001;Hollien, Harry, & Malcik, 1962;Hollien & Malcik, 1967;Hollien. Malcik, & Hollien, 1965;Morris, 1997;Sun et al, 2002;Wang, 2002 For the purposes of this study, a scale numbering system was necessary to coincide with the given pitch frequency.…”

“…Hollien and Malcik found that the African American males in their study had lower median speaking fundamental frequencies than the White males in Curry's study. In a follow-up study, Hollien, Malcik, and Hollien (1965) measured three groups of White southern males and compared the results to the Malcik (1962) andCurry (1940) studies. They found that no differences in the onset of the voice change existed between the White and African American southern males, which led them to speculate that other variables may have accounted for the differences between the southern African American males and northern White males.…”
