Glottalization is the complete or partial closure of the
glottis
The glottis is the opening between the vocal folds (the rima glottidis). The glottis is crucial in producing vowels and voiced consonants.

A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (len ...

In phonetics, a glottalic consonant is a consonant produced with some important contribution (movement or closure) of the glottis.
Glottalic sounds may involve motion of the larynx upward or downward, as the initiator of an egressive or ingre ...

ejectives, with an apostrophe; or (b) with the under-tilde for creaky voice. For example, the
Yapese word for "sick" with a glottalized ''m'' could be transcribed as either or . (In some typefaces, the apostrophe will occur above the m.)
Types
Glottalization varies along three parameters, all of which are continuums. The ''degree'' of glottalization varies from none (
modal voice, ) through
stiff voice () and
creaky voice

() to full glottal closure (glottal reinforcement or glottal replacement, described below). The ''timing'' also varies, from a simultaneous single segment to an onset or coda such as or to a sequence such as or . Full or partial closure of the glottis also allows
glottalic airstream mechanisms to operate, producing
ejective or
implosive consonants; implosives may themselves have modal, stiff, or creaky voice. It is not always clear from linguistic descriptions if a language has a series of light ejectives or voiceless consonants with glottal reinforcement,
[See Ladefoged and Maddieson (1996:74) for the case of Siona] or similarly if it has a series of light implosives or voiced consonants with glottal reinforcement. The airstream parameter is only known to be relevant to obstruents, but the first two are involved with both obstruents and sonorants, including vowels.
Glottal replacement
When a phoneme is completely substituted by a glottal stop , one speaks of glottaling or glottal replacement. This is, for instance, very common in

dialects such as
Cockney and
Estuary English dialects. In these dialects, the glottal stop is an allophone of , and word-finally, and when followed by an unstressed vowel (including syllabic and ) in a post-stress syllable. 'Water' can be pronounced – the glottal stop has superseded the 't' sound. Other examples include "city" , "bottle" , "Britain" , "seniority" . In
some consonant clusters, glottal replacement of /t/ is common even among RP speakers.
