This study aims to explore and tackle different phenomena of syllable structure and syllabification patterns in Jordanian Arabic (JA). The study compares and contrasts the permissible syllable structures in different Jordanian dialects. It also presents a comprehensive analysis of how speakers of different Jordanian dialects tackle the consonantal…

This sociophonetic study examines affricate variation through a continuous lens using diachronic data from Caracas Spanish. We investigate the relationship between frication and occlusion period duration in affricate segments across two steps. First, we present a phonetic characterization of the dependent variable and its variants. Second, we…

This study investigates the acquisition of the Imperfective verb inflection paradigm in Emirati Arabic (EA), to determine whether the learning process is sensitive to the phonological and typological properties of the input. We collected data from 48 participants aged 2;7 to 5;9 years, using an elicited production paradigm. Input frequencies of…

Computational models of child language development can help us understand the cognitive underpinnings of the language learning process, which occurs along several linguistic levels at once (e.g., prosodic and phonological). However, in light of the replication crisis, modelers face the challenge of selecting representative and consolidated infant…

During conversation, talkers may adapt their speech in a variety of ways. One form of speech adaptation is clear speech, in which a talker selectively hyperarticulates segments when faced with specific communication challenges. The present speech production experiment investigated how talkers adapt a common feature of American English dialects:…

When learning a language, typically-developing infants face the daunting task of learning both the sounds and the meanings of words. In this dissertation, we focus on a source of variability that complicates the one-to-one relationship between words and their meanings: wordform variability. In Chapter 1 we make a distinction between the micro…

Automated alignment of transcriptions to audio files expedites the process of preparing data for acoustic analysis. Unfortunately, the benefits of auto-alignment have generally been available only to researchers studying majority languages, for which large corpora exist and for which acoustic models have been created by large-scale research…

The traditional Philadelphia allophonic /ae/ system (henceforth: PHL shown in (1) below) is characterized by a set of complicated conditioning factors and a dramatic acoustic distinction between the two allophones. In recent years, some Philadelphians have begun to exhibit a new allophonic system (NAS, shown in (2) below). Like PHL, NAS is…

Child speech is highly variable. The speech apparatus--the vocal tract, tongue, teeth, and vocal folds--develop at different rates for different children, which helps explain some of the variability in children's speech. For example, the ratio of the oral to pharyngeal cavities changes as children age, making it difficult to establish reliable…

This thesis examines the role of the African substrate languages in the emergence of Atlantic Creole grammatical structures. Alleyne (1980) and Faraclas (1990) have convincingly demonstrated that a survey of the grammatical features that typify the Colonial Era English-Lexifier Creoles of the Atlantic reveals remarkable similarities with those…

The phonological inventory of Old Okinawan is often reconstructed according to modern Ryukyuan languages. Although the importance of historical resources is never ignored in the study of Okinawan historical linguistics, reconstruction based on historical sources is not well investigated yet, due to the two reasons that a) authors of previous…

This paper addresses the process of transcribing and annotating spontaneous non-native speech with the aim of compiling a training corpus for the development of Computer Assisted Pronunciation Training (CAPT) applications, enhanced with Automatic Speech Recognition (ASR) technology. To better adapt ASR technology to CAPT tools, the recognition…

North Kyungsang Korean (NKK) is a pitch accent language in which each word has one of a restricted set of possible tonal patterns, and where the tonal pattern of a given lexical word is not fully predictable. This dissertation reports on a corpus study of accent patterns in existing words and the results of a study in which NKK speakers were asked…

This study examines the frequency effect of two-word collocations involving "para" "to," "for" (e.g. "fui para," "para que") on the reduction of "para" to "pa" (in Spanish) and "pra" (in Portuguese). Collocation frequency effects demonstrate that language speakers…

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…
