Straw phonation, a technique known as Semi-Occluded Vocal Tract (SOVT) developed by
Dr. Ingo Titze, one of the world’s leading voice scientists who has published a variety of academic papers on the topic, operates by creating back pressure. The specially designed narrower size of the Voice Flow Straw generates more back pressure compared to traditional straws, modifying airflow to limit its escape from the body. Normally, as we sing, our vocal folds resist the push of air pressure from the lungs. When using a straw, however, air accumulates in the oral cavity due to our mostly closed mouth. This air pushes back against the lung pressure, optimizing vocal fold positioning, shape, and overall alignment. It promotes smooth vocal fold movement, thereby enhancing efficiency and clarity in voice production.


The thinner the straw, the stronger the back pressure it creates. This increased pressure, coupled with the subtle vibration it generates, aids individuals in finding the best position and shape for their vocal folds without overexertion. Thinner straws consistently maintain this back pressure, helping to reset the shape of vocal folds and making it easier to start vibrating. Furthermore, they enhance the interaction between vocal folds and the vocal tract, ensuring continuous vibration. This improved alignment is particularly beneficial when vocal folds become stiff for higher pitches or swell due to inflammation, resulting in clearer sound production. Regular use of the straw, with variations in pitch and loudness, leads to clearer, smoother, and more resonant sound production. Moreover, it helps muscles remember these healthy 'straw mode' adjustments, enabling vocal folds to maintain optimal performance even when not using the straw, reducing the risk of strain or injury.


Start with three straws (less back pressure) and then progress to fewer straws (more pressure) with practice. Place your lips around the straw to ensure air doesn't escape through your mouth. Be mindful not to exhale through your nose; you can check by plugging your nose while singing. Blow air steadily into the straw; if done correctly, you’ll feel a buzzing sensation in your lips, skull, and the straw.You can then vocalize any exercise or scale through the Voice Flow Straw.
