Ebira English in Nigerian Supersystems: Inventory and VariationIsiaka, Adeiza Lasisi 23 May 2017 (has links)
Die vorliegende Arbeit mit dem Titel „Ebíra English in Nigerian Supersystems: Inventory and Variation“ befasst sich mit einer kleinen Varietät des Nigerianischen Englisch, die für eine Untersuchung aus zwei Gründen besonders geeignet erscheint: Einerseits bin ich selbst Mitglied dieser Volksgruppe, was mir einen besonderen Zugang zu guten, aktuellen und vor allem natürlichen Sprachdaten ermöglicht. Diese sind für eine soziophonetische Untersuchung mit den Konzepten und modernen Methoden der Variationslinguistik von besonderer Bedeutung. Andererseits ist die vorliegende Arbeit keine weitere Studie über die großen Systeme des nigerianischen Englisch oder über die beiden größten und bereits relativ gut untersuchten Systeme des Yoruba-Englisch im Südwesten des Landes oder des Hausa-Englisch im Norden, sondern über eine relative kleine Gruppe dazwischen, die historisch zunächst von den Yoruba und später immer mehr von den Hausa-Sprechern beeinflusst wurde und nach wie vor beeinflusst ist. Diese empirische soziophonetische Studie stellt zwei Forschungsfragen:
FF1) Welches Vokalinventar besitzt Ebíra Englisch? Diese Frage ergibt sich aus den widersprüchlichen Ergebnissen vorheriger Untersuchungen (zu Nigerianischen, Yoruba- bzw. Hausa-Englisch) und soll hier erstmals in einer Analyse von digitalen Aufnahmen von 28 jüngeren und älteren Männern und Frauen (16 bzw. 12) aus den Jahren 2014-2016 untersucht werden. Diese Aufnahmen wurden im Rahmen von soziolinguistischen Interviews gemacht, die die bekannten Sprachstile (nach Labov) umfassen: Wortliste, Lesepassage (die bewährte Kurzgeschichte The Boy who Cried Wolf mit jeweils 90 vorkommenden englischen Vokalen) und Konversation. Diese Frage ist auch vor dem Hintergrund des Einflusses der beiden nahen Hauptvarietäten Yoruba- und Hausa-Englisch interessant (FF1b). Auf der Grundlage von fast 15.000 extrahierten Vokalen erfolgte jeweils nach der sorgfältigen Aussortierung unbrauchbarer oder unvollständiger Daten eine quantitative Untersuchung mit Hilfe des Analyseinstruments PRAAT, mit dem sich die Vokalqualität in Form von Formanten messen und darstellen lässt. Die Untersuchung umfasste die bekannten Monophthongkontraste (nach Wells` lexical sets) FLEECE & KIT, FOOT & GOOSE (+ USE ), LOT & THOUGHT & STRUT , TRAP & BATH & lettER , sowie NURSE , und die relativen Diphthonge FACE , GOAT und CURE.
FF2) Welche sprachlichen und sozialen Variablen können die Variation dieses Ebíra Englisch Vokalsystems erklären? Neben den bekannten sozialen Variablen Alter (bzw. Altersgruppe), Geschlecht, Mehrsprachigkeit und Bildung wurden v.a. die sprachlichen Variablen Vokaldauer, phonetische Umgebung der Vokale und Sprachstil untersucht. Interessanterweise war für eine so detaillierte Analyse der Variation die zunächst recht groß wirkende Anzahl der extrahierten Vokale nicht in jedem Fall groß genug oder nicht gut genug verteilt.

Production and Perception of non-native English in China: Focus on Sociophonetic Variation by Humans and Artificial AgentsAlbrecht, Sven 16 January 2024 (has links)
This cumulative dissertation investigates features of sociolinguistic variation in spoken English by non-native humans and agents. It presents a thorough summary and systematization of previous research on Chinese English, a quantitative analysis of the Chinese English vowel spaces of speakers from Guangdong, Guangxi and Yunnan, a quantitative analysis of durational variation of speakers from different inner, outer, and expanding circle varieties of English, and a study of sociophonetic variation by a pedagogical agent. Furthermore, the thesis proposes a linguistically based quality metric for text-to-speech systems.

Mainland Canadian English in Newfoundland: The Canadian Shift in Urban Middle-Class St. John’sHofmann, Matthias 05 February 2015 (has links)
The variety of middle-class speakers in St. John’s conforms to some degree to mainland Canadian-English pronunciation norms, but in complex and distinctive ways (Clarke, 1985, 1991, 2010; D’Arcy, 2005; Hollett, 2006). One as yet unresolved question is whether speakers of this variety participate in the Canadian Shift (cf. Clarke, 2012; Chambers, 2012), a chain shift of the lax front vowels that has been confirmed for many different regions of Canada (e.g. Roeder and Gardner, 2013, for Thunder Bay and Toronto, Sadlier-Brown and Tamminga, 2008, for Halifax and Vancouver). While acoustic phonetic analyses of St. John’s English are rare, some claims have been made that urban St. John’s speakers do not participate in the shift, based on two or six speakers (Labov, Ash & Boberg, 2006; Boberg 2010). Other researchers with larger data sets suggest that younger St. John’s speakers participate in mainland Canadians innovations to different degrees than mainlanders (e.g. Hollett, 2006). The Canadian Shift has not been uniformly defined, but agreement exists that with the low-back merger in place, BATH/TRAP retracts and consequently DRESS lowers. Clarke et al. (1995), unlike Labov et al. (2006), assert that KIT is subsequently lowered. Boberg (2005, 2010), however, emphasizes retraction of KIT and DRESS and suggests unrelated parallel shifts instead.
In this PhD thesis, I demonstrate the presence of the Canadian Shift in St. John’s, NL, conforming to Clarke et al.’s (1995) original proposal. In my stratified randomly-sampled data (approx. 10,000 vowels, 34 interviewees, stratified as to age, gender, socioeconomic status, and “local-ness”), results from Euclidean distance measures, correlation coefficients, and linear, as well as logistic, mixed-effects regression show that (1) young St. John’s speakers clearly participate in the shift; and that (2) age has the strongest and a linear effect. Continuous modeling of age yields even more significant results for participation in a classic chain shift (6% decrease in lowering per added year). My findings also confirm that the change seems to have entered the system via formal styles (cf. Clarke, 1991, 2010, for TRAP in St. John’s).
Traditionally, the linguistic homogeneity on a phonetic level of the Canadian middle class has been explained by Canada’s settlement and migration patterns of the North American Loyalists from Ontario to the west (cf. Chambers, 2009). Newfoundland’s settlement is distinct, in that the British and the Irish were the only two relevant sources. If settlement were the only crucial reason for a shared pronunciation of Canada’s middle class from Vancouver to St. John’s, the Canadian Shift should be absent in the latter region. I suggest three reasons for middle-class St. John’s’ participation in the Canadian Shift: 1) Newfoundland’s 300-year-old rural-urban divide as a result of its isolation, through which British/Irish features are attributed to rural und lower social class speakers; 2) the development of the oil industry since the 1990’s, through which social networks changed according to the perception of social distance/closeness; and 3) the importance of the linguistic marketplace, which is high in St. John’s due to 1) and 2).:List of Tables viii

Perception and Production of Word Stress Cues in Slavic English VarietiesIvanova, Marina 01 February 2024 (has links)
Word stress is crucial for language perception and production as it enables lexical access and speech segmentation. Phonetically, word stress is cued through higher pitch, duration, and intensity. These cues are weighted differently in production and perception by language learners from different backgrounds. Slavic English learners, especially with a fixed-stress West Slavic language background like Czech but also with a variable-stress South Slavic background like Bulgarian face difficulties in word stress acquisition. Their stress placement errors cannot be fully explained by direct transfer and highlight a more complex relation between the target and the native language. This thesis thus aims to explore the perception and production of English word stress cues by speakers of Slavonic Englishes based on evidence from an EEG study on Slavic and German English word stress cue perception and a phonological and phonetic study on Czech English (CzE) features. These findings are used for the conceptualization of a perception and production training tool. First, the concepts of cue and feature are reviewed in an effort to bridge psycho- and sociolinguistics and create credible language stimuli. Then, the Event-Related Potentials study demonstrates that Slavic and German English speakers successfully process first- and second-syllable stress changes cued through pitch, duration, and intensity. Still, speakers of Slavic languages (with a rather syllable-timed rhythm) perceived first and second syllable stress similarly whereas speakers of German (with a rather stress-timed rhythm) perceived the second syllable deviation as more salient. A study on the role of word stress in the CzE feature inventory shows that syllable-timed rhythm also affects production, as speakers lack vowel reduction and add additional stress to longer words. Compared to Bulgarian English (BgE), CzE shows differences in stress features but an overall lack of consistency in their use to differentiate primary from secondary and unstressed syllables. These findings are integrated in the conceptualization of a High-Variability Phonetic Training (HVPT) system featuring segmentals and suprasegmentals. Overall, this thesis finds group differences in foreign language perception and production of word stress and applies them in the development of customized language learning solutions.:List of Figures ix
