Editing Phonation (section)

===Glottal consonants===
It has long been noted that in many languages, both phonologically and historically, the [[glottal consonant]]s {{IPA|[ʔ, ɦ, h]}} do not behave like other consonants. Phonetically, they have no [[manner of articulation|manner]] or [[place of articulation]] other than the state of the glottis: ''glottal closure'' for {{IPA|[ʔ]}}, ''breathy voice'' for {{IPA|[ɦ]}}, and ''open airstream'' for {{IPA|[h]}}. Some phoneticians have described these sounds as neither glottal nor consonantal, but instead as instances of pure phonation, at least in many European languages. However, in [[Semitic languages]] they do appear to be true glottal consonants.<ref name="Ladefoged"/>{{page needed|date=August 2018}}
