Listener Ratings of Male Singer Technical Ability.

Area of Science:

• Music Perception
• Vocal Science
• Acoustic Analysis

Background:

• Perceptual judgments of singer technical ability are under-researched.
• Previous studies focused on singer vs. non-singer perception and male vocal beauty.

Purpose of the Study:

• To investigate the influence of musical training on listeners' technical ability ratings of male singers.
• To compare listener ratings with objective vocal acoustic measures.

Main Methods:

• An online survey used a Likert-type scale for listeners to rate 27 male vocal recordings singing the vowel [i].
• Listeners were categorized into four groups based on musical experience: nonmusicians, ensemble participants, music students, and music professionals.
• Vocal recordings were analyzed for vibrato rate, extent, and jitter.

Main Results:

• Listener ratings were compared across the four experience groups.
• The study examined correlations between subjective listener ratings and objective acoustic parameters (vibrato, jitter).
• Hypothesis predicted that musically experienced listeners would provide the most severe ratings.

Conclusions:

• Musical training significantly influences the perception and evaluation of male singers' technical proficiency.
• Listener expertise level is a critical factor in assessing vocal performance quality.
• Further research can explore the specific acoustic features that differentiate listener perceptions.
