Use of the DoctorVox Device for Basic Vocal Exercises Contribution to Performance

In this study, a preliminary comparative study was conducted for the first time using the DoctorVox device by instructor–performer participants using two different formant patterns in Turkish and Western music. The participants used the DoctorVox device before recordings to practice the selected tonal exercises ascending and descending; they recorded glissando exercises and [a], [e], [i], [o] vocals in a constant studio setting at Week 0 at the start of the study and Week 8 at the end of the study. The data obtained from the measurements were evaluated in the Customized Praat Program in line with the determined parameters, and thus, the results were revealed. In this study, the measured values of fundamental frequency, jitter, shimmer, harmonic noise ratio, pitch values, maximum phonation time, and voice range improved in all objective measurements. The subjective measurement outcomes indicated that participants’ vocal and breathing health was good, their conditions improved, voices warmed rapidly, felt comfortable in high notes, physical and mental bonding grew gradually, and their confidence increased. In addition, participants’ motivation and professional goals improved, such as delivering performances and adding new pieces to their repertoire. Because of the athletic achievements obtained using the selected tonal vocal exercises as a vocal training method in the study, it is believed that it will help to eliminate existing negative thoughts about the use of (Western) vocal exercises that are methodologically supported by scientific data and will contribute to the present literature for vocal studies.
