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 brief period of creaky voice and slow rise time at vowel onset relative to the voiceless unaspirated stops. However, there is considerable inter-speaker variation in VOT and f0 perturbation, with negligible correlation between these measures, contrary to the predictions of the ejective typologies… 
A preliminary investigation of some acoustic characteristics of ejectives in Waima’a: VOT and closure duration
Waima’a is a little known language spoken in East Timor. From a typological perspective, its stop system is unusual for an Austronesian language: it has a fourway stop system which includes a set of
Tsilhqut'in ejectives: A descriptive phonetic study
Stops are one of the most common sounds across languages of the world. Among these pervasive sounds, ejectives form a unique group that is distinguishable from other types of stops. Their particular
Positional effects on the characterization of ejectives in Waima'a
TLDR
This paper presents results from an ongoing investigation into stop consonants in Waima’a, focusing on the issue of tense v. lax ejectives, and compares ejectives in word-initial and word-medial contexts to address the role of word-position in the tense/lax distinction.
On the acoustic characterization of ejective stops in Waima'a
TLDR
Some acoustic properties of ejective stops in Waima 鈂a (an Austronesian language spoken in East Timor) are examined, and other voiceless stop types that occur in the language are compared.
An acoustic study of trans-vocalic ejective pairs in Cochabamba Quechua
TLDR
It is found that Cochabamba Quechua speakers de-ejectivize one of the two ejectives in such phrases a significant portion of the time, and that, in correct productions with two ejective pairs, the period between the two ejectedives is lengthened by increasing the duration of the vowel and the closure duration ofThe second ejective.
Ejectives in Nez Perce
This paper discusses ejectives in Nez Perce, a Penutian language spoken in western Idaho, northeastern Oregon and eastern Washington. Using words collected in carrier phrases, VOT, burst amplitude,
Classifying Apurímac Quechua Ejectives
I analyze ejective stops in Apurímac Quechua (a variety of Quechua spoken in Southern Peru) in light of the classification system proposed in Lindau (1984) and Kingston (1985), in which ejectives are
Ejectives in Scottish English: A social perspective
This paper presents the results of an analysis of the realization of word-final /k/ in a sample of read and casual speech by 28 female pupils from a single-sex Glaswegian high school. Girls differed

Ejectives in Babine‐Witsuwit’en
Acoustic properties of ejectives in an Athabaskan language of British Columbia were examined. Data from ten native speakers were recorded in the field. Following Hogan [Phonetica 33, 275–284 (1976)],

The purpose of the paper is to investigate acoustic characteristics which distinguish ejectives from pulmonic stops in Ingush (a Northeast Caucasian language), and to compare Ingush ejectives to
The glottal contrast in Babine/Witsuwit’en
Babine/Witsuwit’en, an Athabaskan language, has been said to have a phonemic contrast between voiceless unaspirated, voiceless aspirated, and ‘‘glottalized’’ stops. A study of alveolars in initial
Perception of glottalized consonants in Babine/Witsuwit’en
Previous studies of Babine/Witsuwit’en have shown speaker differences in the production of glottalized stops [Davis and Hargus, J. Acoust. Soc. Am. 100, 2690 (1996)]. The present study investigates
An Analysis of the Temporal Features of Ejective Consonants
Abstract This paper reports some temporal measurements of glottalic ejective consonants. Measurements of pre-release silence before stops, the time from consonant release to vowel onset, and the
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
On pharynx—larynx interactions
TLDR
The objective of this paper is to review the literature relevant to the relationship between these two articulators and to recast some of this information in terms of current articulator-based theories of phonological features such as the ones reviewed in McCarthy (1988).
Information Conveyed by Vowels
Most speech sounds may be said to convey three kinds of information: linguistic information which enables the listener to identify the words that are being used; socio‐linguistic information, which
Hausa glottalic consonants: a laryngographic study
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,
