Area of Science:

  • Speech Science
  • Bioacoustics
  • Human-Computer Interaction

Background:

  • Effective vocal training relies on precise feedback mechanisms.
  • Current tools may lack flexibility in real-time vocal parameter visualization.

Purpose of the Study:

  • To present ALBERT, a software tool for real-time acoustic and laryngeal biofeedback.
  • To address key issues in delivering effective real-time visual feedback for voice development.

Main Methods:

  • Development of the ALBERT software tool.
  • Implementation of user-configurable visual displays and color-based information presentation.
  • Algorithmic combination of vocal parameters for novel real-time metrics.

Main Results:

  • Demonstration of real-time display capabilities for fundamental frequency, jitter, and closed quotient (CQ).
  • Creation of a new parameter correlating CQ with singer's formant energy for progress tracking.
  • User-adjustable information update rates for contextual feedback.

Conclusions:

  • ALBERT provides a flexible and powerful platform for real-time vocal biofeedback.
  • The tool supports advanced vocal analysis and targeted professional voice development.
  • Customizable feedback parameters enhance the efficacy of voice training.
