Adopted Singing Voice Evaluation Models for Work Efficiency in the Recording Industry

Area of Science:

• Vocal performance analysis
• Music production acoustics
• Recording engineering

Background:

• Industry demands necessitate high singing efficiency.
• Singers' work efficiency is often assessed by rework times (RwT) in recording studios.
• Previous research synthesized nine critical factors from acoustic and recording practices.

Purpose of the Study:

• To understand and predict singers' work efficiency controls.
• To identify key factors influencing rework times during vocal recording.
• To analyze the relationship between vocal parameters and recording efficiency.

Main Methods:

• Literature synthesis to identify influencing factors.
• Measurement of nine potential variables with ten singers performing the same song.
• Analysis of 380 musical passages using multiple linear regression.

Main Results:

• Rework times (RwT) are primarily predicted by intensity, singing duration, and rhythm consistency.
• Vocal intensity significantly negatively impacts RwT.
• The interaction between intensity and singing duration positively affects RwT.

Conclusions:

• Intensity and singing duration are key predictors of vocal recording efficiency.
• Singers' adjustment of intensity and duration influences rework times.
• Understanding these factors can optimize vocal production in studios.
