0 relating to or produced by the glottis (= an opening in the throat that is closed when you swallow or make particular sounds): --
In such a pattern, nasal harmony would be facilitated by substituting a nasal or glottal stop for an obstruent stop or by deleting the latter.
The other two show equally strong positive associations between laryngealised sounds and glottal stops, and between ejective sounds and glottal stops.
The occurrence of the glottal stop is an automatic result of phonetic implementation, which cannot give rise to phonological contrast.
All of these observations present a much more complex picture of states of the glottis than the mono-valve, mono-dimensional glottal continuum model described above.
The glottal vocal folds can oscillate anteriorly along the ligamental glottis, while remaining open posteriorly.
Note that the prevocalic insertion of the glottal stop is not limited to word-initial positions and is thus more indicative of morphemic than word boundaries.
In fact, 68 % of tokens have voicing throughout the interval where the glottal articulation is perceived.
The majority of the 145 vowels are accompanied by secondary laryngeal, pharyngeal or glottal articulations.
