ABSTRACT
Glottal closure before (=preglottalization) or after (=postglottalization) a speech sound. Preglottalized consonants are closest to implosives, postglottalized are closest to ejectives. Preglottalized vowels can be found occasionally in English when, for example, a speaker attempts to avoid running words ‘not at all’ (see Moulton 1962); postglottalized vowels are found in the Sino-Tibetan language of Tsaiwa-Jingpo. In preglottalized vowels, one also speaks of abrupt onset of voicing, e.g. in in Ger.
