The study investigates the relationship between lexical encoding and production in order to establish whether learners are able to produce a difficult contrast in words that they merged in their mental lexicon. Forty American English learners of Russian were tested on their production and lexical encoding of familiar and highly-frequent words with…

Lexical access is highly contextual. For example, vowel (rime) information is prioritized over tone in the lexical access of isolated words in Mandarin Chinese, but these roles are flipped in constraining contexts. The time course of these contextual effects remains unclear, and so here we tracked the real-time eye gaze of native Mandarin speakers…

This paper explored and analyzed features of English pronunciation that could cause intelligibility problems for Nepali English learners (ELs), who use English as a foreign language (EFL) or English as a second language (ESL). We examined the Nepali ELs' pronunciation issues by juxtaposing them with comparable segmental and suprasegmental features…

The purpose of this study is to investigate the uniqueness of the pop singing genre by determining the role of the Chinese language in the creation of popular singing in education with modern innovative technologies. The paper began by determining which types of popular music were the most popular among respondents and the influence of modern…

Purpose: Evidence increasingly indicates that people with developmental stuttering have auditory perception deficits. Our previous research has indicated similar but slower performance in categorical perception of the speech sounds under the quiet condition in children who stutter and adults who stutter (AWS) compared with their typically fluent…

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children's ability to express phrasal combinations at the one-word stage of…

Recent findings have revealed that very preterm neonates already show the typical brain responses to place of articulation changes in stop consonants, but data on their sensitivity to other types of phonetic changes remain scarce. Here, we examined the impact of 7-8 weeks of extra-uterine life on the automatic processing of syllables in 20 healthy…

Classic typologies within prosody tend to treat 'tone' languages as being diametrically opposed to 'stress' languages. However, Hyman (2006) highlights several languages that can have both, including Seneca, Fasu, and Copala Trique. As language documentation advances and our acoustic methodologies in the field are further refined, we have seen…

Purpose: There is a lack of standardized Mandarin reading text material that could potentially elicit significant variations in fundamental frequency (F0) and in vocal intensity for clinical voice evaluation. In this study, a phonetically balanced "Three Bears Passage" was developed based on the classical "Goldilocks" story for…

Vowel nasalization usually occurs through a two-step process whereby a vowel is nasalized via coarticulation with a nearby nasal segment; when the language later drops the nasal segment, a nasal vowel remains. Spontaneous vowel nasalization is a rare, peculiar form of nasalization that emerges in contexts that lack an historical etymological nasal…

Purpose: This study examined the acoustic properties of Taiwanese (Southern Min) lexical tones produced in esophageal speech (ES) and pneumatic artificial laryngeal speech (PAL), including onset fundamental frequency (F0), slope of F0 contour, duration, and amplitude (intensity) of the vowel portion of syllables carrying seven Taiwanese tones.…

Millions engage in learning a Second Language (L2) using their mobile devices with a wide range of success. Concomitantly, there exists a growing interest in research on the effects of mobile-assisted language learning and predictors of learner outcomes (e.g., Loewen et al., 2020; Sudina & Plonsky, 2023). However, few of these apps and studies…

This dissertation presents three studies that examined issues related to the production and the perception of pitch in a tone language. The first study examined linguistic contexts that may modulate consonant-induced pitch perturbations (CF0) in a tone language. Previous studies have produced mixed findings regarding the role of linguistic…

This dissertation documents a collection of sociolinguistic and sociophonetic studies of the speech of bilingual Korean Americans in California. Korean Americans are an ethnic minority in the United States whose speech patterns in Korean and English remain understudied. The goal of the studies is to begin sketching out the acoustic traits that…

The Possible Word Constraint, or PWC, is a speech segmentation principle prohibiting to postulate word boundaries if a remaining segment contains only consonants. The PWC was initially formulated for English where all words contain a vowel and claimed to hold universally after being confirmed for various other languages. However, it is crucial to…
