Area of Science:

• Phonetics and Speech Science
• Vocal Pedagogy
• Acoustic Analysis

Background:

• The Complete Vocal Technique (CVT) is a method for voice training.
• Understanding the acoustic correlates of vocal efficiency and economy is crucial for singers and speech-language pathologists.
• Previous research has explored various acoustic parameters in phonation, but a comprehensive analysis linking specific parameters to CVT principles is needed.

Purpose of the Study:

• To investigate the acoustic parameters of 'metal' and 'density' in phonation within the context of the Complete Vocal Technique.
• To determine if these parameters can differentiate between vocal efficiency and vocal economy.
• To provide a double-case study analysis with special reference to vocal efficiency and economy.

Main Methods:

• Acoustic analysis of phonation using the Complete Vocal Technique.
• Focus on the parameters described as 'metal' and 'density'.
• Double-case study methodology to examine individual vocal characteristics.

Main Results:

• The examined parameters ('metal' and 'density') were found to distinguish between different aspects of vocal production.
• Specific trends were observed in relation to vocal quality (CQ) and GRbasal (GR), indicating their influence on vocal efficiency and economy.
• The study identified distinct patterns associated with efficient and economical phonation based on the analyzed acoustic features.

Conclusions:

• The acoustic parameters 'metal' and 'density' are significant indicators for differentiating vocal efficiency and economy in the Complete Vocal Technique.
• The findings contribute to a deeper understanding of the acoustic underpinnings of CVT, supporting its principles with empirical data.
• Further research is warranted to explore the broader applicability and implications of these acoustic parameters in voice science and pedagogy.
