How To
Less Strain / Tension
Over 69% of customers say they experience a reduction in strain / tension when speaking or singing.
Easier Warmups
Most customers say that their warmups and exercises are much easier when using Resono.
Better Breath Control
Customers say that they experience better breath control overall after using Resono.
Faster Recovery
27% of customers note that they experience faster vocal recovery with Resono as compared to without.
Our Recommendations
3-5 Times / Week
Our customers notice the best results when using the Resono within their routines at least 3-5 times per week.
Explore Resistance
Don't just set and forget. Make sure you continually adjust and explore resistance to cater to what your voice needs.
Implement & Balance
Interweave straw phonation work within your normal routines, making sure to have a good balance of work for your needs.
Our data shows that customers who combine Resono and Vocalitea throughout the week report higher satisfaction and greater benefits overall. So next time you're training with the Resono, consider having a Vocalitea before hand and see how your voice feels after!
Trusted by the Pros
Our singing straw tools are used by Singers and Professional Voice Users from over 40 countries around the globe, as well as by Broadway, West End, and Television/Film Stars, from shows like Les Miserable, Wicked, Hamilton, Frozen, Phantom of the Opera, Hadestown, Cabaret, and so many more.
This is a game changer for vocal warmups.
It is the absolute holy grail to singing... It really helps with the fluidity of voice.
The Science Behind Resono
Discover some of the research and data behind our innovative SOVT tools.
Resistance, Visualised.
We've run 1000s of simulations exploring the vocal benefits of our devices, and we've built a brand new mathematical model that allows us to accurately determine the back-pressure offered by any configuration of the Resono, singing straw, or regular straw.
Research
Academic research has shown that SOVT exercises create a balance between subglottal and supraglottal pressures, which helps optimize vocal fold vibration. Studies indicate that these exercises can:
- Reduce phonation threshold pressure, making phonation easier.
- Improve vocal economy, allowing singers to produce sound with less effort.
- Decrease vocal fold collision forces, reducing strain and potential vocal damage.
- Enhance resonance and projection without forcing the voice.
A 2006 study by Ingo Titze found that phonating through a narrow tube increases intraoral pressure, helping to stabilize the vocal folds and encourage efficient vocal fold oscillation. This means that using the right level of resistance in straw phonation can significantly impact vocal training and therapy outcomes.
Resistance Range Comparison
The chart above visualises the range of resistance (also known as "back pressure") that different types of straw can provide. Most have a fixed resistance due to their fixed aperture and length, but the Resono is dynamic and can change resistance.
Many singers use regular drinking straws for SOVT exercises, but here’s the catch: A fixed-length and diameter straw will only ever provide one level of resistance. This means it may not be suitable for all singers or all vocal training situations. Having an adjustable resistance system allows for more precise control over vocal load, just like adjusting weights at the gym.
Small but MIGHTY
From one small device comes so much power. With our patented device, you get a huge back-pressure range, from 1.5 cmH2O to 30 cmH2O and beyond (if using the VARA).
What does "back-pressure" do?
Back-pressure (technically “supraglottal pressure”, interchangeable with "resistance") is the gentle cushion of air that builds up above the vocal folds when the vocal tract is partially closed by a straw.
That extra pressure helps to lower phonation-threshold pressure (the effort needed to start the folds vibrating) and reduces collision forces each time they meet.
At the same time, the narrow exit raises acoustic inertance - think of it as an elastic “push–pull” that feeds energy back to the folds - so they vibrate more efficiently and with less muscular strain. The net effect is easier onset, more stable tone and a lower risk of fatigue or injury.
The Resono Pro lets you dial in exactly the right resistance for your voice, giving you the sweet-spot of back-pressure without guessing or juggling multiple straws.
Common Mistakes
| Mistake | Why It's A Problem | Quick Fix |
|---|---|---|
| Air leaks at lips or nose | Lowers back-pressure and defeats the purpose. | Seal lips firmly around the straw and pinch the nose closed to check flow. |
| Jaw or lip tension | Adds constriction and raises effort. | Keep jaw neutral and cheeks relaxed. |
| Using the same resistance for every task | One size doesn’t fit all ranges/dynamics. | Match resistance to the goal and don't be afraid to increase or decrease as your voice demands. |
| Pushing too much air | Might cause excess tension or build too much pressure. | Relax/back off the flow. You can try using some water or the Spinner to visualise the output. |
Sing like never before
Rayvox tools are designed to help you train your voice, and reach new vocal heights, build muscle strength, coordination, and efficiency that lasts a lifetime. You can truly build the voice you want: eliminate voice cracks, achieve better vocal fold closure, avoid strain and vocal tension, improve your breath control, and sustain notes for longer and more efficiently. All from one device. You can even do it on the train!
