Why does your voice shut down when it matters most?

The answer isn’t confidence - it’s a whole-system issue, starting in your nervous system.

In this episode, voice coach and actor Mattie Shisko explores the powerful link between the nervous system and authentic expression.

We dive into vocal liberation, practical tools to regulate your body and voice, and why safety (not confidence) is the foundation of being heard. Mattie also shares insights from working with politicians and leaders under pressure, revealing what it really takes to sound grounded, clear, and human when it matters most.

Expect practical exercises, fresh perspectives on vocal confidence, and a deeper understanding of how your voice impacts both you and those around you.
