VOICEBALANCEVOICE & BREATH
VOICEBALANCEVOICE & BREATH
VoiceBalance is the only SOVT voice and breathing trainer that keeps the semi-occluded vocal tract while you articulate. Studio-grade training, anywhere you go.
Straws and lip trills fix the constriction in place, so you cannot articulate. They train the voice, yet the bridge to real singing and speaking stays broken. VoiceBalance was created to cross that gap.
The mouthpiece wings sit between your teeth and lips, so the semi-occluded environment holds even as you move your jaw through A-E-I-O-U. That is why training transfers naturally into real singing and speech.
Semi-occlusion raises supraglottal pressure, narrowing the pressure gap across the vocal folds so they vibrate regularly without slamming together. Less vocal load, less throat squeeze — we change the pressure environment instead of telling you to relax.
A compact design that fits in one hand. Practice at night without disturbing neighbors, and care for your voice with short warm-up and cool-down routines around performances and lectures.
| Straw / lip trill SOVT | VoiceBalance | |
|---|---|---|
| Articulation | Impossible — fixed constriction | Free — semi-occlusion maintained |
| Transfer to real singing & speech | Training and performance separated | Train while articulating — direct transfer |
| Voice + breathing together | Partial | Pressure control + breath support in one |

Most voice problems come down to the balance between the pressure pushing up from below the vocal folds and the pressure building above them. VoiceBalance teaches your body that balance.
※ VoiceBalance is a voice and breathing training device. For persistent voice symptoms, please consult an ENT specialist or a certified voice trainer first.
Rest the mouthpiece between your teeth and lips and the semi-occluded environment is set. Air keeps flowing naturally through the vent hole.
Hum on a comfortable pitch and feel the balance between your breath and the pressure supporting your folds from above.
Move through A-E-I-O-U and scales. Semi-occlusion holds throughout, so the training carries straight into real singing and speech.
Every symptom has a different mechanism. VoiceBalance supports each situation by changing the pressure environment — never by forcing.
※ Everything here is written from a training perspective. If you have pain or persistent symptoms, see an ENT specialist or consult a certified voice trainer first.
Voice, breathing, and everyday speech. Tap the tab that fits you.
Training for singers, musical-theatre performers, and speakers. Expand the cheeks and pharyngeal space in a comfortable range, hold a steady exhale, then extend upward step by step through vowel transitions and short scales.
Use the device's resistance to train inhalation and exhalation muscles progressively. Start by sipping air in and blowing it out, then raise the intensity within a safe range as you adapt.
Hoarseness, an unconfident tone, throat tension after long conversations. Teachers, lecturers, and counselors can use a short vocal warm-up before class or sessions.
Straws and lip trills fix the front constriction, so articulation is impossible. VoiceBalance's mouthpiece wings sit between the teeth and lips, keeping semi-occlusion intact while you articulate and move your jaw — the core difference.

Two core routines on video: vocal training and breathing training with VoiceBalance.
In the age of K-pop and auditions, more people than ever want to sing well or work with their voice. Yet learning to sing has always demanded years and money — and poor teaching could waste both.
So I built VoiceBalance — a trainer that restores the voice's balance: powerful, resilient sound for professionals; an open tone and easier high notes for musicians; and a confident voice for everyone.
I hope you will build your own beautiful, refined voice with VoiceBalance.
