Breathy voice in a vocal spectrum
A breathy tone can be intentional. The spectrum becomes useful when you compare how much breathiness changes from one attempt to another.
Noise floor
Breath noise can fill the area between harmonic peaks. Instead of clear isolated lines, the graph may look more cloud-like.
Weak harmonics
H3 and H5 may become less distinct when closure is lighter, but microphone level and room noise can create similar effects.
Practice comparison
Sing a breathy onset, then a more balanced onset, on the same note and vowel. Capture both and compare the graph shape.
When to seek help
If breathiness is persistent, unwanted, or paired with pain or fatigue, use professional evaluation rather than online graph interpretation.
How to check this in the analyzer
Choose one note, one vowel, and one microphone distance. Capture the graph before and after one small change. Start by comparing pitch stability, then H1/H3/H5, then F1/F2/F3 candidates.
This is practice feedback, not medical diagnosis or a final technique label. The best result is a sound that is comfortable, repeatable, and useful for the music.
