The Cyber-Tone Vocal Conditioning System (VCS) is an adjustable SOVT (semi-occluded vocal tract) vocal trainer for singers, voice teachers, choir directors, and speakers. Unlike disposable singing straws or single-resistance straw tools, the VCS features adjustable back pressure for progressive vocal conditioning, helping you sing with better voice clarity, range, and consistency. Use it for vocal warm-ups, breath control exercises, vocal range building, and resonance training. As a voice trainer device, the dial sets a repeatable level of back pressure instead of leaving it to guesswork. Reusable, durable, and designed for daily voice training routines.

How Can This Improve My Singing?
How Can This Improve My Singing?
How the Cyber-Tone VCS Works
When you sing through the VCS, airflow meets controlled resistance inside the device.
This creates a small amount of back pressure in the vocal tract.
That pressure helps balance the forces acting on the vocal folds, allowing them to vibrate more efficiently.
In voice science this is known as semi-occluded vocal tract (SOVT) training, a technique widely used in vocal pedagogy and voice therapy.
Singers often experience:
• smoother register transitions
• more stable tone
• reduced vocal effort
• improved airflow coordination
• increased vocal stamina
Because of these effects, SOVT exercises are commonly used in vocal warm-ups, vocal therapy, and professional voice training programs.
How the VCS Works
How the VCS Works
The Science Behind the VCS (Fair Warning, This One Gets a Bit Nerdy)
The Cyber-Tone Vocal Conditioning System (VCS) is built on the principles of Semi-Occluded Vocal Tract exercises, often called SOVT.
SOVT exercises are widely used in vocal pedagogy, speech-language pathology, and professional voice training. Examples include lip trills, humming, and phonating through a straw or tube.
So what’s actually happening?
When you partially narrow the vocal tract while phonating, it increases supraglottal air pressure the air pressure above the vocal folds. That pressure helps balance the forces acting on the vocal folds, allowing them to vibrate more efficiently and with less collision stress.
Source: Titze IR, "Regulation of laryngeal resistance and maximum power transfer with semi-occluded airway vocalization," Journal of the Acoustical Society of America, 2021 (doi.org/10.1121/10.0005124).
In simpler terms:
the vocal system becomes better balanced, more efficient, and easier to coordinate.
Research on SOVT techniques has shown measurable improvements in several markers of vocal function, including:
• Lower phonation threshold pressure (less effort needed to start phonation)
• Improved vocal efficiency and coordination
• Smoother transitions between vocal registers
• Reduced perceived vocal effort
• Improved recovery from vocal fatigue
Source: Titze IR, "Regulation of laryngeal resistance and maximum power transfer with semi-occluded airway vocalization," Journal of the Acoustical Society of America, 2021 (doi.org/10.1121/10.0005124).
Because of these effects, SOVT exercises are widely used by:
• Voice therapists
• Speech-language pathologists
• Professional vocal coaches
• University voice programs
Why Adjustable Resistance Matters
Most SOVT tools, including basic straws, have fixed resistance determined by their diameter.
But research shows that tube geometry directly controls the amount of airflow resistance and pressure generated, meaning different sizes produce different training loads.
Source: Smith SL & Titze IR, "Characterization of Flow-resistant Tubes Used for Semi-occluded Vocal Tract Voice Training and Therapy," Journal of Voice, 2017 (doi.org/10.1016/j.jvoice.2016.04.001).
The challenge is simple:
Every voice is different.
A resistance level that feels perfect for one singer may be too easy, or too demanding, for another.
That’s where the Cyber-Tone VCS is different.
Instead of forcing you to adapt to a fixed resistance level, the VCS provides infinitely adjustable airflow resistance.
This allows singers to:
• Start with light resistance for warm-ups or vocal resets
• Increase resistance gradually for conditioning and coordination training
• Dial in a setting that works for their voice, their range, and their goals
Think of it like having an entire set of vocal training straws built into one compact tool.
Professional Voice Science, Refined Into a Portable Tool
SOVT exercises have been studied and used for decades in clinical voice therapy and vocal training.
The Cyber-Tone VCS takes those same principles and refines them into a clean, portable, adjustable system designed for real singers in real environments rehearsals, backstage warm-ups, lessons, and daily vocal maintenance.
Voice science, simplified and made practical.
Dial In Your Sweet Spot
Dial In Your Sweet Spot
Every voice responds differently to airflow resistance.
Using the precision adjustment at the base of the VCS, you can increase or decrease resistance in small increments until the voice feels balanced and efficient.
Exterior reference notches make it easy to return to your preferred setting.
Your goal is simple:
Find the level where phonation feels easy, stable, and controlled, never forced.
When the resistance is dialed in correctly, many singers notice:
• smoother airflow
• easier phonation
• more stable tone
• reduced effort while singing
That’s your sweet spot.
Who Uses SOVT Training
Who Uses SOVT Training
Semi-occluded vocal tract exercises are widely used across the professional voice world.
They are commonly used by:
• vocal coaches
• speech-language pathologists
• university voice programs
• choir directors
• studio and touring singers
• musical theater performers
Many singers use SOVT exercises daily for warm-ups, vocal maintenance, and recovery.
The Cyber-Tone VCS simply makes these techniques portable, adjustable, and easy to use anywhere.

Train the System, Not Just the Sound
Many singers try to improve by pushing for more volume or power.
But efficient voices rely on coordination, not force.
SOVT training helps the vocal system develop a healthier balance between airflow, pressure, and vocal fold vibration.
As efficiency improves, singers often experience:
• greater endurance
• more consistent tone
• easier register transitions
Efficiency builds strength.
Efficiency builds consistency.
That’s the foundation of vocal conditioning.

Train Your Voice With Certainty.
Singers have warmed up through straws for decades — SOVT training works.
But a straw has one resistance, and your voice doesn't. It changes with the day, the repertoire, and the shape you're in.
The Vocal Conditioning System was built for that reality. Start light, then dial up resistance as your voice wakes up — strengthening coordination across your registers while protecting the instrument.
No guesswork. No random pressure. Deliberate, repeatable training, the way athletes build strength.
It's how serious singers prepare — including the 2026 international champion Ambassadors of Harmony.
Because better singing isn't accidental. It's trained.
There are multiple things I love about this tool:
1. Lanyard - it is SO handy! I underestimated how much I would like that part.
2. Design - I like that I can more easily hear if I'm properly supporting with air or pressing without enough air. I get this feedback much better from the VCS than a straw.
3. These above two things make me love it even more so the fact that it's purple also made the list :)
Vera, thank you so much for this! You made my day. I love that the lanyard surprised you. It's a small thing, but having it right there means it actually gets used instead of sitting in a drawer. And you put your finger on exactly why I designed it this way. A straw doesn't tell you much, but the VCS lets you hear right away whether you're truly supported with air or just pushing. That instant feedback is what helps your voice grow, a few minutes a day. And purple is a great choice. Keep singing, and thank you again for taking the time to share this. Will Jarrett, founder, Cyber-Tone
I have tried another brand of vocal trainer. That was a long slim stick, and I gave that to a friend because I didn’t really feel that it was that useful of the breathing techniques that I learned watching how to use it was good enough for me, but I decided to try your vocal trainer and I like it much better. I like the shape of it better I like the way you can just simply dial the resistance on it and it does help me to warm up and open up my throat. I would recommend it to anyone.
Kevin, Thank you so much. I try not to take reviews too personally (especially the bad ones...) But when you design, create and market a product and people truly like it, it does something for me as an inventor/entrepreneur that really makes me feel good about helping people create music. I'm very thankful and humbled by your review. Thank you. Will Jarrett Founder Cyber-Tone
I'm in my 70s andsing with the music team in our church. I usually do some form of warm ups before the service but noticed that my range was not what it once was or could be again. I'd never worked with singing straws, but was familiaar with the concept so when I ran across Cyber--Tone and the Vocal Conditioning System I was interested in the concept. I haven't had it long. Before this past weeks practice I worked with the VCS for about 10-15 minutes before the music team arrived. I have to say my voice did feel freer and I noticed less of a tendency for my voice to be strained. Then on Sunday, the worship leader asked if I wouldn't mind supporting him with the melody's instead of harmonizing because his voice wasn't where he felt he couldn't carry it on his own. That meant I would be challenging myself to hit notes I wasn't normally comfortable with....but with the VCS warm up I was able to move into that range well enough to where I was able to be the support he needed me to be. So, it looks like I'll be warming up this way all the time. Thanks! I've encourage the rest of the vocalists to give it a look as well/
Amazing! Thank for your detailed review and congrats on the progress you are making. Will Jarrett Founder Cyber-Tone
Just started using this device but it seems to be improving my breath control and resonance. I’m not much of a singer (some choral work) but I’m an audiobook narrator. Might be a good untapped market for you!
Hi Barry, we're thrilled to hear the Vocal Conditioning System is helping with your breath control and resonance! Thanks for sharing your experience, and we love the idea of it being useful for audiobook narrators too. Happy recording! Will Jarrett Founder Cyber-Tone
It’s been a few weeks and I’m a regular user and have felt and heard the results come through… A+ product at a great price!
Thanks for sharing your experience Eric. I'm glad to hear that you are getting regular reps in with the VCS and are feeling and hearing the difference. Will Jarrett Founder Cyber-Tone
This clever convenient little device keeps my Medicare-aged voice in excellent condition. While I have regularly done straw phonation, it's not always convenient to have a straw and a cup with water. Wearing this little gem around my neck allows me to prepare to sing at home and at chorus rehearsal.
Hi Susan, Thanks for brightening my day with this wonderful review. I'm so glad you like it. Will Jarrett Founder Cyber-Tone
My voice has been steadily improving in the week I’ve had my CyberTone. I find it much easier than a plastic straw and having it hanging around my neck makes it convenient for driving. Thang.
Philip, Amazing testimony. Thanks for your review. Will Jarrett Founder Cyber-Tone
I've had my VCS for about two weeks and I love it. I use it aevery morning on my drive to work (about 20 minutes) and I can already tell that something is changing and improving. I am excited to see what improvements will be after a couple of months.
That is amazing. I do a lot of warm ups in the car with my VCS as well. I too am noticing changes. Simply amazing! Thanks for your thoughtful review. -Will, Founder Cyber-Tone.
This Is the third type of vocal trainer I have tried and it is great! The adjustable resistance is by far the best. In the other two, the resistance is restricted by “clicks.” This trainer allows for more freedom in choosing levels. Definitely a must have if you are interested in developing range, breath support, etc.
Thank you for your positive feedback on our Vocal Conditioning System! We are happy to hear that you have found our adjustable resistance feature to be beneficial in your vocal training journey. We strive to provide versatility and freedom in our products to help our customers achieve their desired vocal goals. Thank you for choosing our system and we wish you continued success in your development. Keep singing!
I've been using this maybe 3 times a week for just a few minutes and I have noticed a difference!
I'm so glad to hear you are noticing a difference. Thanks so much! Will Jarrett Founder Cyber-Tone
I wanted to like this. It does offer you a wearable SOVT tool; however, the cap kept falling off and the insert would unscrew itself. After owning it about a month I’ve lost both of those pieces because they fell out while
I was wearing it.
Hi there, I'm sorry to just be hearing about this in a review. Some of our early units had some tolerance issues. And we stand behind our products. I'll try to find your contact information from your order and reach out to you directly and offer you a replacement or refund, whichever you prefer. Okay, wishing you all the best. Thank you, Will Jarrett, Founder Cyber-Tone.
Works great to gently warm up my voice and smooths out tone and "interferences"
Hi Jolene, Thank you for your review. Will Jarrett Founder Cyber-Tone
It makes the whole training process easier
Thank you. Will Jarrett Founder Cyber-Tone
I love the product worth every penny
Thank you. Will Jarrett Founder Cyber-Tone
I'm not sure I know how to use it. I have the directions but Don't understand how it helps, when before I sing do I use it, and how often. I sing in our VERY small Catholic Church choir. I've been cantoring every third week for two years and this week, I was quite "squeaky", a bit less smoothevthan I usually try to sound.
Hi there, thanks for sharing this—and for bringing your voice to your choir and cantoring. I'm sorry the directions haven’t made it clear how to use the Vocal Conditioning System. In genera, just a few minutes per day before and even after any heavy vocal use. Here is a list of all of our vocal education resources. I think you'll find some good information here. If you. have anything specific let us know. https://cyber-tone.com/blogs/vocal-education. Thanks! Will Jarrett Founder Cyber-Tone
Hi Will! I'm still practicing with it. I like to use with some YouTube vocal exercises videos with sounds that are easy for me to do with the Cyber-tone. Then before I practice my songs, and last week in the car before I went into rehearsal. My goal is to make my vocalizing smoother, and not experience the harshness at the back of my throat that happens an hour after we start rehearsals.
Btw, the warm-ups my director does with us are more open mouth singing, and not compatible with the devise, and that's on with me (my husband says I should use it AT rehearsal and nope, that won't work)
I'll update you folks later!
Hi there! Thanks for sharing how you’re fitting the Vocal Conditioning System into your practice and rehearsal routine. Let us know how we can help. Will Jarrett Founder Cyber-Tone
Poor directions and video didn’t sufficiently explain how to use the product.
Hi Jean, I’m sorry our directions and video didn’t clearly explain how to use the Vocal Conditioning System. We are working on more content. Here is the single most comprehensive content I have today. If you are not happy with the VCS, then please reach and as we have a 30 day money back guarantee on our products. Thanks so much. Will Jarrett Founder Cyber-Tone
I’ve been using it in the car every time I drive and it seems to be effective. My first gig since getting it is in a couple of days and I’ll definitely use it on the way to the gig and see how my voice performs.
Hi Thomas, Thanks so much for your review. Let us know if you have any questions. Will Jarrett Founder Cyber-Tone
Haven't had mine long and still trying to find my "sweet" spot but I notice a difference after using it. The adjustable bottom doesn't like to stay in place, moves in between uses.
Hi Chanda, thanks for sharing your early experience. I'm glad to hear that you're noticing a difference. Will Jarrett Founder Cyber-Tone
Nice quality
Thank you, Will Jarrett Founder Cyber-Tone
