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. Support the showDisclosure: This podcast uses AI-generated synthetic voices for a material portion of the audio content, in line with Apple Podcasts guidelines. We make rigorous science accessible, accurate, and unforgettable.Produced by Michelle Bruecker and Scott Bleackley, it features reviews of emerging research and ideas from leading thinkers, curated under our creative direction with AI assistance for voice, imagery, and composition. Systemic voices and illustrative images of people are representative tools, not depictions of specific individuals.We dive deep into peer-reviewed research, pre-prints, and major scientific works—then bring them to life through the stories of the researchers themselves. Complex ideas become clear. Obscure discoveries become conversation starters. And you walk away understanding not just what scientists discovered, but why it matters and how they got there.Independent, moderated, timely, deep, gentle, clinical, global, and community conversations about things that matter.  Breathe Easy, we go deep and lightly surface the big ideas.Spoken word, short and sweet, with rhythm and a catchy beat.http://tinyurl.com/stonefolksongs
