Effect of training with a simple overtone flute on the voice production

Original language description

Objective Breath management is one of the basic foundations for controlling voice production, voice quality and loudness. The aim of this study was to investigate the effects of training with an overtone flute on the voice. Method Ten vocally untrained normophonic women participated in an overtone flute training program over a period of 3 to 5 weeks. The subjects received no additional voice training. Voice range profiles (VRP) and maximum phonation time (MPT) were measured before and after training. Changes in VRP parameters as well as Singing Power Ratio (SPR), LTAS and contact quotient from the electroglottographic signal (CQ) were compared using pairwise comparisons statistical tests. Results The MPT significantly increased on average by 3.4 s. The results confirm the subjects' ability to achieve higher SPLs in speaking (stage) and when singing a glissando. They were also able to achieve higher pitches during calling. After training, there was an overall significant increase in SPL, particularly in the mf- dynamic range between F4 and D6. In the ff- dynamic, increased loudness was observed only in the highest part of the tonal range (A5-D6). EGG showed a significant decrease in CQ for the loudest call, and similar reduction in CQ when singing in fortissimo dynamics in the transition region between the M1 and M2 vibratory mechanisms (G4-C5). The SPR values increased essentially in the M2 mechanism and in the highest pitches (F5-D6) of the voice in ff-dynamics and in the middle range (D5-F5) in mf-dynamics. Conclusion The ability to maintain the same SPL with reduced CQ for the ff-dynamics and increase SPL without changing CQ in the mf-dynamics can be attributed to an improved efficiency in voice production in which amplification is not only achieved at the glottal level by adduction. An increase in SPR may have been caused by the involvement of epilaryngeal resonance. Results demonstrated an improvement of the breath support.
