The classifier scores both overlap with each typical range and distance from its center. It deliberately calls close results borderline because voice type is not reducible to endpoints.
What the estimate considers
The ranked result combines coverage of each typical range with proximity to its center. If the first two scores are close, both are shown and the result is marked borderline.
Range is one input. Tessitura, timbre, passaggio, training, and repertoire require human listening.

Questions and limitations
Can vocal range alone determine my voice type?
No. Range is useful evidence, but classical classification also considers tessitura, timbre, passaggio, vocal weight, training, and repertoire. This tool therefore gives an estimate and shows borderline matches instead of presenting a range-only result as a professional diagnosis.
Why does the test ignore very brief notes?
A microphone can mistake breath, room noise, or a harmonic for an extreme pitch. A note must remain clear and stable for at least 300 milliseconds before it changes your result, which favors notes you can actually sustain.
