SOVT Streaming Course


In this 4 hour CPD accredited streaming course, learn the core science and theory behind semi-occluded vocal tract exercises/straw singing, how and why they work, as well as how to select the right straw configuration for the person you're working with.

Straw phonation is hugely popular, but does size matter? And should it be in or out of water?

SOVT (semi occluded vocal tract) exercises have been used by singing and voice teachers for decades. We know that they work, but we don't always know why. Three expert voice teachers; Gillyanne Kayes, Jeremy Fisher, and Oren Boder have teamed up to teach you the science and theory behind these transformative techniques. Understanding the why of SOVT will help you answer the important questions of which straw for which singer, when you should use water and what effect it has, and what changing the diameter or length of the straw does for voicing. We've taken care of the science, made it super accessible, so you can start implementing these techniques straight away!

Workshop style demonstrations

Throughout the course we will be explaining how SOVT works with live demonstrations, explainers, and interactive learning. You'll also explore our unique technique for honing in on the most appropriate straw configuration for you/your students.

Lecture Style Format

There will be lecture style learning throughout, with animations and examples to help conceptualise the science and theory. Plus - Gillyanne and Jeremy will jump in to add some exceptional insights and thoughts from their wealth of vocal knowledge.

Observational Learning

You will get to watch the experts teach from an observational perspective, gaining valuable insights into their methods. You'll understand how individual differences truly make a difference as you observe the unique responses to SOVT work from each of the participants.

Checkout our book, Singing Through A Straw Can Make You An Awesome Singer. The book explores the science behind semi-occluded vocal tract exercises, whilst also diving into the different techniques, sounds, and applications for SOVT. You'll learn why I think using a straw dominates the SOVT exercise domain, with immensely practical techniques that I believe every single teacher, singer, and voice user should use as part of their daily teaching/vocal routine.

The content is concise and full of value. So thankful for this course. I totally recommend it!

It helped me understand the physics of all the process of breathing and phonation in a very graph...

It helped me understand the physics of all the process of breathing and phonation in a very graphic, scientific and easy way. I had been doing SOVT Exercises for a while, but this course and Oren's intelligence and easy way to explain it made it so much easier for me to understand and to teach. Thank you Oren. I loved how scientific based this whole course was, I loved how graphic it was, I loved all the explanations and graphics Oren uses, I loved how practical it was and how balanced it was both on practice and theory. I feel so much better prepared to share the knowledge with my students. I understood the difference between training SOVT exercises with or without water. In so many ways. As a singer I can't wait to get my SOVTSTRAW to start working my exercises with it. As a teacher I feel I have so many better ways of explaining why and how all this works for my students. A must take training both as a voice professional - weather you are a singer, a teacher, a voice over artist, a dubbing artist, an actor, a salesperson or simply someone that uses wants to take better care and understanding of his/her voice.

Eye opening and mind blowing.

To give me a deeper understanding of the science, so that it can help me to explain to my students WHY we are doing these exercises, and what they do. Clear, detailed, professional, comprehensive, educational. The use of DC and AC back pressure using water....amazing!! I have a greater understanding of all the elements of SOVT. I will now incorporate SOVT elements into all my vocal sessions. Eye opening and mind blowing.

Rennae Vanderlaan
A MUST Course for SOVT!!

Who knew there was so much to learn about a straw and my voice preference?! Aside from being a HUGE learning experience it was soooo much fun too!! Thank you!!

Jackie Harrison
Straws and SOVT. One size does not fit all!

Informative, practical and in my opinion absolutely ESSENTIAL if you ever plan to use straws in or out of water for SOVT exercises.

Alison Benz

You already know that SOVT straw phonation is really good for our voices, but this course will really illustrate clearly WHY.

A fantastic learning experience- whether you’re new to it like me or a more experienced performer
