Introduction: Phonation tubes in water are commonly utilized in voice training, aiming to enhance voice quality and minimize impairments.
Aim: This study examines the impact of using a wide resonance flexible tube submerged in water on voice and respiratory characteristics in healthy individuals.
Methods: A cross-sectional design involved 10 healthy participants aged 18-40,divided into two groups with sustained phonation using a submerged tube for either 1 or 3 minutes. Acoustic, aerodynamic, and electroglottographic (EGG) measures were assessed at three stages: pre-exercise, immediately after, and post-exercise.
Results: The findings suggest that wide resonance tubes may be beneficial in voice training for enhancing voice and respiratory characteristics in healthy individuals. Further research with larger sample sizes is recommended to confirm these effects and to explore broader clinical applications in voice training and rehabilitation.
