What is the difference between Asprite and Glottal onsets?
Aspirate and glottal onsets represent opposite ways the vocal folds (cords) and breath coordinate to initiate sound. The core difference lies in whether airflow begins before the vocal folds close (Aspirate) or if the vocal folds close and build pressure before releasing sound (Glottal).

We offer a range of specialized services tailored to meet your individual needs. Our approach is focused on understanding and responding to what you require, providing effective and practical solutions.
Aspirate onset
An aspirate onset (breathy start) initiates airflow before the vocal cords close, creating an airy, whispery sound (like an "h").
-Folds start apart and come together after air flows.
-Breathy, airy, soft, or whispery.
-Gentle, relaxed airflow.
-Can cause quick breath depletion or fatigue if overused.
-Pop, jazz, intimate ballads, or emotional styling.
Glottal Onset
A glottal onset (hard attack) forcefully clamps the vocal cords shut before the breath hits, building pressure that releases with an abrupt, sharp pop.
-Folds press firmly together before air flows.
-Abrupt, sharp, focused, or "popping".
-Sensation of a tight closure or a small "slap" in the throat.
-Can cause strain or nodes if done habitually with too much force.
-Pop, country styling, or emphasising abrupt text.
