Tools for every voice
Books, assessments, and training tools — everything I build comes from real teaching experience and a commitment to helping voices grow.
Ted's Voice Academy offers voice training products including the Adaptive Voice Framework book ($9.99–$42.95 on Amazon), PASS Profile communication assessment ($49.99–$59.99), Intonation Lab ear training web app ($99–$999, with free demo), and Riser Chart visual riser placement tool for chorus directors ($99, supports 200+ singers with 24 voice parts). All products are developed by Ted Chamberlain from four decades of voice teaching experience.

Over four decades of teaching, I've developed tools that extend what happens in the studio. Each product on this page grew out of a real need I saw in my students — a clearer way to understand vocal function, a way to measure communication style, a tool for training intonation by ear. They're practical, field-tested, and designed to help you keep growing between lessons and beyond.

Built from the studio
Every tool on this page grew out of my teaching practice. The AVF book captures four decades of vocal study in one framework. PASS Profile turns communication self-awareness into something measurable. Intonation Lab makes ear training precise and visual with AI coaching feedback and 29 intervals and chords. Riser Chart puts four decades of directing experience into a visual riser placement tool with 24 voice parts, singer photos, batch editing, and exports that look like your organization made them.
These aren't theoretical products — they're practical tools I use with real students and ensembles every week. And there's more on the way.
