- For
- Voice teachers, singers, and vocal-acoustics students
- Worth noticing
- Its five-vowel teaching anchors use manually set C4 values; other pitches are extrapolated, not singer-by-singer measurements.
Field notes
The controls connect tongue height, frontness, jaw opening, lip shape, larynx position, and soft-palate position to vowel and resonance displays. The model’s C4 anchors are manually assigned, with other pitches extrapolated; the page explicitly distinguishes these teaching values from measured singer data. Personal recordings can be exported, while locally saved work may be lost if browser data is cleared or the site address changes.
