glottal

The researchers measured the opening between vocal folds—known as the glottal gap—as they opened, closed, and vibrated while the women spoke at different pitches.

Every glottal stop in Rebekah del Rio's "Llorando," the Spanish rendition of Roy Orbison's "Crying" performed in Club Silencio, was punctuated by the sounds of some dude drifting in and out of consciousness.

It’s actually a glottal sound, meaning it emanates from the glottis, in the back of the throat — a muscle English speakers don’t get to exercise much.

Under Ms. Gustern’s guidance, she began to exhale before hitting certain notes and to pronounce an ‘h’ before glottal strikes.

Meanwhile, a weasel-like animal called a fisher waited nearby, making glottal noises inside a wire trap.
