The Chadic (Afroasiatic) language Hausa, spoken mainly in Nigeria and the Republic of Niger, has a series of ‘glottalic’ obstruents. This includes both ejectives ([k’], [s’] or [ts’]; orthographic κ, ts) and two other consonants which have often been described as ‘implosives’ and are represented by the IPA symbols for implosives in Hausa orthography (б, d). In addition, there is a ‘laryngealized’ palatal glide (orthographic ‘y). The description of orthographic б, d as implosive has been called… 
Affricating ejective fricatives: The case of Tigrinya
The production of an ejective fricative involves an aerodynamic dilemma. An ejective requires increased intraoral air pressure, while a fricative requires air to be continuously vented through a
Explosives, implosives, and nonexplosives: the linguistic function of air pressure differences in stops
Nonexplosive stops, including implosives and other stops regularly lacking an explosive release burst, occur in roughly 20% of the world's languages, yet their phonological and phonetic properties
Gender differences in the realization of vowel-initial glottalization
The results show that female subjects realized the glottalized vowel onsets with greater maximum vocal fold contact duration than male subjects and that the glattalized vowels produced by females were more clearly distinguished from the non-glottalization controls.
On the categorization of ejectives: data from Witsuwit'en
Results of an acoustic study of root-initial /t th t'/ for eleven speakers of Witsuwit'en (Athabaskan) are presented. Values averaged across speaker means suggest that Witsuwit'en ejectives have a
Feature Patterns: Their Sources and Status in Grammar and Reconstruction
In each of the three main dimensions of this work – developing phonological profiles of specific sound types, exploring implications for grammar design, and historical problem solving – I find evidence that cognition maintains extensive awareness of the phonetic values of the variables it manipulates.
Feature economy in sound systems
This study shows that feature economy can be used as a tool in phonological feature analysis, and offers voiced aspirates, voiceless sonorants and various types of glottalised sounds as illustrations.

The glottalic consonants of Hausa.
This thesis is concerned with the examination of the glottalic consonants of Hausa, a Chadic language spoken in northern Nigeria, Niger, Cameroon, Togo and Ghana. The glottalic consonants constitute
Phonetic differences in glottalic consonants
Data on glottalic consonants in a number of languages were examined. Data on implosives come from Hausa, Degema, and three Eastern Ijo languages, all spoken in Nigeria. Ejective data come from Hausa
