The voice behind the breathing sequences
Several times a day, a voice guides Radio Odyssey listeners through slow breathing and back toward a steadier heart rhythm. That voice belongs to Elisabeth Bélot-Grimaud, a doctor of cognitive psychology. The sequences were designed and recorded with her, as part of her exclusive partnership with the station — you can hear them on heart coherence breathing radio.
Her background
- Doctorate in cognitive psychology
- Researcher and lecturer in psychology, specialising in positive mental health
- Two postgraduate university diplomas, in micronutrition and in health prevention
- Postgraduate university diploma in meditation and breathing practices
- Author of « Programmez votre cerveau pour le bonheur »
- TEDx speaker, twice
- Host of the podcast « L'instant Beau Bien Bon »
She has developed several frameworks of her own within her approach to positive mental health — D.O.S.E.®, ENCÉFAL® and Beau Bien-Bon® — which she sets out on her website.
Why heart coherence, and why her voice
Heart coherence breathing rests on slow, regular breathing at around 6 breaths per minute. Done properly, it brings heart rate variability into a smooth, wave-like — sinusoidal — curve, associated with a measurable state of physiological calm. It is one of the few biological levers you can deliberately pull, in a matter of minutes.
Rather than broadcast a generic sequence, Radio Odyssey chose to have one designed and recorded with a genuine specialist: someone whose university diploma in meditation and breathing practices, and whose expertise in positive psychology, make the practice grounded rather than approximate.
The station also made a simple but uncommon choice: a human voice rather than a synthetic one. No AI, no robot guiding your breathing — a real person, with her own breath, intonation and natural pace.
On air
You will find these sequences in the Radio Odyssey stream several times a day — see how to fit them into a workday.
That meeting is also what brought the station back online in 2025 — the full account is in the story of Radio Odyssey.
Hear her voice, on video
Elisabeth Bélot-Grimaud has published a guided heart coherence session set to music on her YouTube channel — the same exercise, and the same voice, as the one broadcast on Radio Odyssey. The spoken guidance is in French, but the breathing rhythm carries on its own.
Her work beyond Radio Odyssey
On her website santementalepositive.fr, Elisabeth Bélot-Grimaud publishes free resources organised around three pillars: biological (sleep, movement, nutrition, breathing), cognitive (memory, attention, learning) and psychological (emotions, relationships, meaning). She describes heart coherence breathing there as "one of the simplest and best documented tools for regulating stress". The site is in French.
