Global nonverbal communication norms reflect colonial erasure of indigenous vocal traditions and classed power hierarchies
Original framing: “Laughter, sighs and screams reveal unwritten social rules in everyday life” — Phys.org
Indigenous vocal traditions—such as the *yodelling* of Swiss and Austrian Alpine communities or the *yodeling*-like *khoomei* of Tuva throat singers—demonstrate that nonverbal sounds are often deeply tied to land, identity, and resistance. The suppression of these practices under colonialism (e.g., bans on Māori *haka* in New Zealand schools) reveals how vocal expression becomes a site of power struggles. Western research typically extracts these sounds as 'data' without acknowledging their cultural sovereignty or the violence of their erasure. For instance, the *click languages* of Southern Africa, where consonants are produced with tongue clicks, challenge Eurocentric phonetic frameworks entirely.
The original framing treats nonverbal sounds as ahistorical, apolitical phenomena, obscuring their roots in colonial suppression, class stratification, and cultural resistance.
Indigenous traditions like Māori *haka* or Inuit throat singing demonstrate that these sounds are not 'unwritten rules' but codified systems tied to identity and sovereignty, systematically erased by Western science. Marginalized groups—from enslaved Africans to modern protesters—have used vocalizations as tools of subversion, while trickster figures like Anansi or Coyote expose the absurdity of rigid social norms through irony and inversion. The solution lies in decolonizing communication studies, centering marginalized voices, and designing digital platforms that preserve and amplify erased traditions, thereby restoring agency to communities whose vocal practices have been treated as mere data points in a colonial archive.
