Science in the press

"Straw phonation not only lowered the onset of normal voice, but also elevated the onset of chaotic voice, indicating a better voice economy and voice control. Moreover, the improved phonatory range demonstrated that straw phonation had the potential to prevent voice users who have high voice demand from voice fatigue and vocal damage."

Kang et al., 2018

"We think Semi-occluded Vocal Tract exercises are brill. They have a solid of research behind them and have been helping singers clinically for years. Bringing these into your daily warm up routine, or even more than once per day, will help you to warm that uncooperative little monkey into a beautifully functional instrument in half the time." 

iSingMag, 2016.

"The straw phonation exercise caused positive effects, seen upon voice self-assessment, indicating an easier and better voice upon phonation."

Costa et al., 2011.

"Narrowing the vocal tract increases air pressure above the vocal folds, keeping them slightly separated during phonation and reducing the impact collision force"

Brilliant customer service, my order was to be a Christmas present for my son, I had a problem with my initial order and it was sorted out immediately thanks to Oren.

Joe Lundy

I’ve been using a plastic straw with my vocal exercises, and felt some benefits with my air flow and vocal strength. This however brings that to a completely different level! One 5 minute use and I feel the workout of using the SOVT. This is going to be an absolute game changer in my musical career. Thank you RAYVOX :)

Essential tool for all singers

The Resono is a game changer when it comes to developing, strengthening and continuing one’s singing. I’ve been using it for a week now and while I’ve been using straws for the past 6 months the ability to increase or decrease intensity and pressure is outstanding. I can hear the difference in my recordings and feel the ease of reaching those top notes.
Exceptional customer service as well. My case was damaged in the post and was replaced immediately. I will definitely recommend this company and this instrument to all my singer friends.

Love it

Used this as my introduction to straw phonation technique- been using it as part of my warmup before performances. Actually game changing. Obviously it is part of a wider technique and process but wow wow wow- the way my voice felt that night and the confidence it’s given me moving forward. Thank you!
