Vocal onset and closure in the spectrum
The beginning of a note often reveals whether the sound is too airy, too pressed, or balanced enough to continue.
Breathy starts
If noise appears before pitch locks in, the vocal folds may not be closing efficiently yet.
Pressed starts
If the first moment spikes hard and the throat feels tight, the onset may be too forceful even if the graph looks energetic.
Balanced starts
A balanced onset usually locks pitch quickly and lets harmonics continue without a harsh attack.
Try it in the analyzer. Run the four-second check, then compare it with your next attempt.
How to check this in the analyzer
To apply this article, start with one comfortable note, one vowel, and a fixed microphone distance. A single graph is less useful than repeated captures under the same conditions.
After capturing the graph, compare it with your next attempt. Look for pitch stability, whether H3 and H5 remain visible, and whether F1 or F2 candidates move when the vowel changes. These cues are practice references, not medical or professional diagnosis.
