Host Dave Asprey sits down with Roger Love, the celebrity voice coach who trained Bradley Cooper, Tony Robbins, Selena Gomez, and Brendon Burchard. Roger has spent decades teaching actors, executives, and performers how to master their voice to create influence and impact. In this conversation, he shares the science behind vocal tone and the emotional cues hidden in your breath.

You’ll hear why most people speak from the wrong part of the body and how that drains power from every interaction. You’ll learn how digital habits dull your voice, which techniques make you sound more confident and trustworthy, and why sound can heal the nervous system. Dave and Roger also explore how voice training supports your biology, boosts emotional control, and protects your performance as you age.

This episode gives you tools to speak with more authority, connect on a deeper level, and improve your health through one of your most underused systems: your voice. If you want to lead, perform, persuade, or simply feel heard, this conversation shows you how to upgrade the way you sound—and how you feel when you speak.

• Why most people speak from the wrong part of their body

• How your voice shapes the way others feel about you

• The link between vocal tone, breathing, and nervous system health

• How to sound more confident, persuasive, and emotionally resonant

Mindsip insights from this episode:

Speak powerfully with melody and control to avoid anger perception

To sound powerful without being perceived as angry, you must combine loud volume with melody and a controlled pace, as anger is conveyed by loud, fast, and monotone speech.

#emotion

Understand why you dislike your recorded voice

You dislike your recorded voice because when you speak, you hear it through bone conduction which sounds deeper, but a recording only captures the air-conducted sound that others hear.

The Bodyguards Red Light Converter is a screen protector that converts harmful blue light from your phone into beneficial red light to improve sleep and support skin health.

Train airflow techniques to improve speech disorders

Conditions like stuttering and spasmodic dysphonia can be improved by training the person to use solid, consistent airflow from the diaphragm, as these issues often stem from a lack of air.

#breathing

Utilize sound to heal and transform emotional states

Humans are their own sound healing machines, capable of making specific sounds to change their brain's function, stress levels, and emotional state.

#stress

Share your voice as a gift to others

Your voice is a gift you package and give to others, and its value is determined by how they receive it, not by how you feel about it.

#relationships

Reclaim emotional connection by choosing analog sound over digital audio

Listening to digitally processed sound, like streaming music or podcasts, is a downgraded experience that lacks the emotional connection and physical vibration of real, analog sound.

Breathe correctly to enhance speaking skills

To speak correctly, you should breathe in through your nose, let your stomach come forward slightly, and then only speak as your stomach relaxes inward without any forced pulling.

#breathing

Master emotional communication to become AI-proof

To become AI-proof, you must master emotional communication through your voice, as AI will never be able to authentically process and create emotions second-by-second.
