What they found overturns a decade of cultural certainty: men creak more than women. Older speakers creak more than younger ones. And the reason society got this so spectacularly backwards has everything to do with pitch contrast, cognitive bias, and the fact that our brains actively rewrite what our ears receive.In this episode of Heliox: Where Evidence Meets Empathy, we take a deep dive into the sociophonetics of creaky voice — unpacking the biomechanics of the larynx, four objective acoustic metrics, the observer's paradox, presbyphonia, and the psychological phenomenon of perceptual false alarms. By the end, you will never hear a voice the same way again.What you'll learn:Why vocal fry is a biological reality, not a trendHow men's voices fly under the perceptual radarWhy young women became the scapegoat of an acoustic illusionWhat 92,000 vowels tell us about how bias shapes perception••How to apply this evidence to your own listening — and your own judgmentsReference: A sociophonetic study of creaky voice across language, gender and age in Canadian English-French bilingualsThis is Heliox: Where Evidence Meets EmpathyIndependent, moderated, timely, deep, gentle, clinical, global, and community conversations about things that matter.  Breathe Easy, we go deep and lightly surface the big ideas.
