“…The bottom right panel shows spectral information using three lines. The three lines are a)power spectrum (a green line), b)temporally interference-free spectrum (a red line), and c)spectrum without temporal and frequency interferences (a bold black line) [8]. The vertical axis represents the sound pressure level when calibrated.…”

We introduce real-time and interactive tools for assisting vocal training. In this presentation, we demonstrate mainly a tool based on real-time visualizer of fundamental frequency candidates to provide information-rich feedback to learners. The visualizer uses an efficient algorithm using analytic signals for deriving phase-based attributes. We start using these tools in vocal training for assisting learners to acquire the awareness of appropriate vocalization. The first author made the MATLAB implementation of the tools open-source. The code and associated video materials are accessible in the first author's GitHub repository.
