L0 · Health Overview
Warm-Up / Cool Down
Guided vocal recovery session with three SOVT exercises for warming up before singing or cooling down after practice.
Vocal Health Score
Provides a comprehensive assessment of your overall phonation quality, calculating a score from 0–100 based on multiple parameters.
Symptom Detection
Detects multiple common vocal symptoms in real time, helping you identify and improve your phonation habits.
Pitch Detection
Displays the current fundamental frequency (Hz) and corresponding note name in real time, helping you accurately identify your pitch position.
Pitch Recording
Real-time pitch history line chart recording your singing trajectory with snap and real pitch modes.
L1 · Phonation Basics
Resonance Depth Detection
Evaluates the resonance depth of your voice, reflecting larynx position and pharyngeal resonance.
Vocal Fold Closure
Displays the degree and type of vocal fold closure, helping you find an efficient and healthy phonation approach.
Fold Balance
Displays the current vocal fold thickness during phonation (thick ↔ thin vibration) and the degree of closure. Teaching uses a TA/CT ratio to describe this balance (teaching imagery).
Singer's Formant Monitor
Displays the projection ability and carrying power of your voice, reflecting the concentration of high-frequency energy. Closely related to the singer's formant.
Larynx Position
Displays the vertical position of the larynx in the neck. Larynx position affects vocal tract length and vocal timbre.
Waveform
Displays the amplitude variation of the audio signal in the time domain. The X-axis represents time and the Y-axis represents amplitude intensity.
Loudness Meter
LUFS (Loudness Units relative to Full Scale) is a perceptual loudness unit based on human hearing, following the ITU-R BS.1770 international standard.
Onset Detection
Detects the onset type at the beginning of phonation. Onset type has a significant impact on vocal fold health and voice quality.
