An Acoustic and Aerodynamic Analysis of Consonant Articulation in Bininj Gun-wok
|

Abstract:
© 2013 Dr. Hywel Martin Stoakes ; This thesis is an acoustic and physiological phonetic analysis of the consonant system in Bininj Gun-wok (BGW), an Australian language spoken in North Western Arnhem Land. The primary aim of this thesis is to provide a detailed phonetic description of an Australian language looking at the articulation of intervocalic stops and nasals. This investigation examines a number of phonological contrasts in the language that have not had prior phonetic investigation. The analysis is divided into three experiments, the first two of which focus on differences in length and strength between stop series in BGW. The third experiment examines patterns of coarticulation within nasals. The materials used consist of two corpora with a total of 24 first language speakers of BGW. Corpus I includes five speakers of the Kuninjku variety and Corpus II includes 19 speakers of the Kunwinjku variety, all recorded under field conditions in Western Arnhem Land. Corpus I is made up of acoustic recordings and Corpus II, physiological recordings with associated time-aligned audio. An important phonological feature of BGW is a two stop series that contrasts for length. The two stops in the series, which are all matched for place of articulation, are phonologically classed as lenis or fortis. The primary focus of this study is to determine the phonetic realisations of these stop categories. The secondary focus of this study is to examines patterns of coarticulation between nasals and stops in BGW, as nasalisation can mask the acoustic cues that are needed to perceive place of articulation. Earlier cross-linguistic studies have consistently shown that duration is a key difference between stop categories within a language. This is particularly for languages that do not use voicing as a cue to the contrast. In the current study, acoustic analysis is used to measure duration and for analyses of burst characteristics of BGW stops. An articulatory analysis investigates differences in strength and also the prevalence and timing of voicing between the stop series. Findings show that there is a clear durational difference between lenis and fortis stops. Voice onset time differences are dependent on place of articulation rather than reliably signalling between stop categories. In addition there is a clear difference in strength in terms of peak intra-oral pressure. In the study, medial homorganic articulations are separated into three categories termed lenis, fortis and geminated consonants. These represent short intra-morphemic stops, long intra-morphemic stops and long inter-morphemic stops respectively. Fortis stops and geminates clusters do not differ in terms of duration. There are however measurable differences between them including pressure — pressure measured over time — showing that duration and pressure are independent. The timing of pressure peak is similar for lenis and fortis stops is similar, yet geminates show a delay in the intra-oral pressure peak. Across languages, anticipatory nasalisation is thought to be under direct control of the speaker. Carry-over nasalisation in contrast has proven to be a result of bio-mechanical inertia. The secondary focus of this thesis is an examination of nasalisation and directionality of nasal assimilation in BGW as well as the durational aspects of nasals in clusters. Aerodynamic results show that the rise of the nasal airflow, in medial nasals, is delayed to be almost coincident with the oral occlusion. The inference is that the velum is closed during the preceding vowel and opens quickly at the onset of the nasal. In a cluster of nasals followed by a stop, the nasal has a greater duration than the stop. In clusters of stops followed by nasals, it is the stop that has the greater duration. This suggests strengthening in a medial position. The post-tonic medial position is prosodically eminent, as this is where the majority of phonetic contrasts are found for Bininj Gun-wok and Australian languages in general. This investigation into medial consonants in BGW represents the first major phonetic investigation into stop articulation in an Australian language and provides key support for this proposition.
