Objective:
This study investigates whether animal vocalizations can promote more efficient registration management compared to traditional vocal exercises in untrained treble singers.

Methods / Design:
A mixed-methods experiment will compare the perceptual and physiological effects of traditional versus animal mimicry exercises among treble-voice participants (ages 18–35) with limited formal training. Each participant will complete two counterbalanced sessions in randomized order: (A) animal mimicry and (B) traditional vocalises. Vocal behavior will be assessed using electroglottography (EGG) to measure open and closed quotient ratios, the Acoustic Voice Quality Index (AVQI) for acoustic change, and the OMNI-Vocal Effort Scale (OMNI-VES) for perceived effort. Participants will also complete an engagement questionnaire regarding their comfort, ease, and likelihood of applying each method.

Results:
It is expected that both exercise types will improve registration stability, indicated by more consistent EGG measures post-exercise. However, animal mimicry exercises are hypothesized to yield greater reductions in perceived vocal effort and higher engagement scores, suggesting enhanced vocal efficiency with reduced cognitive load. Data collection is ongoing.

Conclusions:
Integrating animal mimicry into the voice studio may offer a creative and physiologically effective alternative for developing registration balance in beginning singers. By combining acoustic, perceptual, and physiological data, this study seeks to broaden the evidence base for vocal training, supporting playful and exploratory strategies as viable tools for improving coordination and ease of vocal production.
