The Social Life of the Human Voice
Joshua RaclawNerd Nite MadisonNovember 2015
The Human Voice
• The human voice has a wide range of social meanings
• Variation across languages, cultures, and time
• But what do we mean when we talk about the voice?
The Human Voice
• But what do we mean when we talk about the voice?
• Sound from vocal fold vibration
resonating in head/throat cavities
• Air from the lungs moves…
• Varies in loudness, pitch, and
quality (phonation)
The Vocal Folds
• Introducing you to your vocal folds
• Vibration of the vocal folds
• Fingers to throat: /f/ and /v/, vowels, whisper
• Vocal fold
activity a huge
part of variation
in the voice

The Vocal Folds
• Really introducing you to your vocal folds
• Can alter length and tension
to produce higher or lower
pitch; go into falsetto; etc.
…Isn’t science awesome?
More About Vocal Pitch
• Pitch is a frequent social marker of gender
• Physiological (sex-based) basis for pitch differences
• Length, size, and tension of vocal folds affects pitch:
• Testosterone thickens and lengthens vocal folds
• In adult men, average 60% longer (Titze, 1989)
Physiology and Vocal Pitch
• But significant variation exists in and across genders
• On average, women measure 225 Hz, men 120 Hz
• But average pitch
ranges show
significant overlap:
• So men and woman have the potential to use the same pitch
Shifts in Vocal Pitch
• So men and women have potential to use same pitch
• And we know this because with proper training, we
can significantly alter the everyday pitch of our voice
• Margaret Thatcher dropped ~50 hz
• There’s also voice
feminization training:
Cross-Cultural Variation
• Significant cross-cultural variation in pitch as well
• Average pitches in men:
• German 161 Hz, Polish 138 Hz, American 119 Hz
• Average pitches in women:
• Japanese 232 Hz, American 214 Hz, Dutch 191 Hz
• Japanese women
up to 400 Hz
Cross-Cultural Variation
• Significant cross-cultural variation in pitch as well
• Average pitches in men:
• German 161 Hz, Polish 138 Hz, American 119 Hz
• Average pitches in women:
• Japanese 232 Hz, American 214 Hz, Dutch 191 Hz
• Japanese women
up to 400 Hz
Accounting for Variation
• These are all shifts in average overall pitch
• Why these shifts? Likely a mix of physiological,
sociocultural, and evolutionary factors at stake.
• Let’s talk a bit more about culture, baby. And how
we understand the meanings of vocal pitch.
Understanding Vocal Pitch
• Beliefs about vocal pitch are also powerful things
• Used to social effect, as in media:
David ProwseJames Earl Jones
Understanding Vocal Pitch
• Beliefs about vocal pitch and sex/gender even
motivated this Australian study from 2011:
• Low Pitched Voices Are Perceived as Masculine and
Attractive but Do They Predict Semen Quality in Men?
• It was published in PLOS ONE.
• Isn’t science awesome?
• (Also, for those of you wondering, it doesn’t.)
Cross-Cultural Variation
• But even these beliefs may vary cross-culturally:
• Among groups in Yemen, adult male tribesmen often
use creaky voice and a high tenor, near falsetto, in
ritual greetings to rend “manhood” and “virility”
• Among Lachixío Zapotec speakers in in Oaxaca, similar
voice quality conveys respect; used to address God in
prayer, deceased relatives, or community elders
More to Explore
• More to be explored about pitch is used and
understood in context:
• Men and women speak drop ~6.5 Hz when leaving
voicemails to hotties (Hughes et al., 2010)
• Women apparently also raise ~6.5 Hz when leaving
voicemails to hotties (Fraccaro et al., 2011) ?
• And what’s with
these potatoes:
