  • To provide a framework for understanding acoustic signal variations.
  • To complement existing voice analysis strategies.

Main Methods:

  • Review of principles in acoustic voice analysis.
  • Conceptualizing voice communication with layered protocols.
  • Systematizing acoustic signal variations.

Main Results:

  • Acoustic analysis is a valuable tool for voice assessment.
  • Understanding signal variations is key to accurate interpretation.
  • A layered protocol model can organize acoustic data.

Conclusions:

  • Non-invasive acoustic analysis has limitations and strengths.
  • A systematic approach enhances the interpretation of voice data.
  • The proposed model aids in understanding vocal function and dysfunction.
