A great deal of the research on cross-linguistic phonetic influence demonstrates that a speaker's knowledge of their first language (L1) significantly affects their ability to perceive and produce sounds in any other language. While current studies show that cross-linguistic transfer occurs at the L3 level, some research suggests that properties…

To account for the full range of language use in contemporary multilingual urban contexts, the notion of target language (TL) needs to be reconsidered. In studies of second language acquisition and language variation, taking TL for granted implies that people agree on what constitutes "good" language, or the standard norm. The TL of…

Recent research has shown that speakers are sensitive to non-contrastive phonetic detail present in nonnative speech (e.g. Escudero et al. 2012; Wilson et al. 2014). Difficulties in interpreting and implementing unfamiliar phonetic variation can lead nonnative speakers to modify second language forms by vowel epenthesis and other changes. These…

While considerable dialectal variation exists, almost all varieties of Spanish exhibit some sort of alternation in terms of the palatal obstruent segments. Typically, the palatal affricate [??] tends to occur in word onset following a pause and in specific linear phonotactic environments. The palatal fricative [?] tends to occur in syllable onset…

Individual voices are not uniformly similar to others, even when factoring out speaker characteristics such as sex, age, dialect, and so on. Some speakers share common features and can cohere into groups based on gross vocal similarity but, to date, no attempt has been made to describe these features systematically or to generate a taxonomy based…

This dissertation studies the realization of the rhythm of Taiwan Mandarin and focuses on the quality of its unstressed (neutral-tone) syllables. Taiwan Mandarin (TM) is often described as more syllable-timed than Standard Mandarin (SM). In TM, the unstressed syllables occur less frequently. The quality of the unstressed (neutral-tone) syllables…

This dissertation investigates the linguistic and social constraints on the occurrence of creaky voice quality (creak) in Beijing Mandarin (BM), as well as the effect of linguistic and prosodic context on creak's social meanings for Mandarin listeners. It is a two-phase study, composed of 1) a production study of the distribution of creak in the…

A fundamental challenge for human cognition is perceiving and acting in a world in which the statistics that characterize available sensory data are non-stationary. This thesis focuses on this problem specifically in the domain of sentence comprehension, where linguistic variability poses computational challenges to the processes underlying…

The dissertation study aims to contribute mainly to the field of loanword phonology in general and particularly to Indonesian and its phonology that are rarely studied to date. The study investigates what consonantal and syllabic repair strategies are employed by Indonesian in adapting Arabic and Dutch loanwords, whether these adaptation…

Within a variationist approach for data collection and analysis, this study investigates the acquisition in perception of post-vocalic word-final stops (codas) by speakers of Brazilian Portuguese learning English as a foreign language in a classroom environment. Because codas are illicit in this variety of Portuguese, the hypothesis holds that…

Dutch listeners were exposed to the English theta sound (as in "bath"), which replaced [f] in /f/-final Dutch words or, for another group, [s] in /s/-final words. A subsequent identity-priming task showed that participants had learned to interpret theta as, respectively, /f/ or /s/. Priming effects were equally strong when the exposure…

The current study lays the groundwork for a model of Mandarin tones based on both native speakers' and non-native speakers' perception and production. It demonstrates that there is variability in non-native speakers' tone productions and that there are differences in the perceptual boundaries in native speakers and non-native speakers. There…

The idea that vowel nuclei in many northern European languages can be divided into peripheral and non-peripheral categories is discussed. Peripheral vowels are those located at the edge of the vowel envelope, and non-peripheral nuclei are those located on the inside. This assertion has not received as much scrutiny as it should. There are at least…
