Empower Your Voice

Built by a Singer, for Every Voice

Rayvox began in 2019 with one idea: give every singer and speaker the tools the West End warms up with. I'm Oren Boder, singing teacher and inventor, and this is how it happened.

The Story

Three Acts So Far

Act I

The Stage and the Studio

I grew up on stage, trained in vocal technique at the Royal Central School of Speech and Drama, and have spent about 15 years teaching voice: one to one, in masterclasses and in lectures.

The Inventor

In 2019 I founded Rayvox and built the first Resono: a singing straw with adjustable resistance, now patented in the UK, Europe and the USA. Resono Go, Resono Flex and Vocalitea followed.

The Builder

Then software: Evita.ai, a finalist at the Great British Entrepreneur Awards, then Hey Maestro, which I co-founded, and now Rayvox Studio, the free app for practice and lessons.
