The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…

Bilingual child ability in two languages is become popular issue in the comparison of those two languages. In this paper, the Indonesian bilingual child has parent, school and course using English actively, then his environment using Bahasa Indonesia. This research was conducted to measure ability and difficulties faced by bilingual child in…

Late second language (L2) learners often struggle with L2 prosody, both in perception and production. This may result from first language (L1) interference or some property of how a second language functions in a late learner independent of what their L1 might be. Here we investigate prosody's role in determining information structure through…

This study examined the acceptability of a mobile application, "SpeechPrompts," designed to treat prosodic disorders in children with ASD and other communication impairments. Ten speech-language pathologists (SLPs) in public schools and 40 of their students, 5-19 years with prosody deficits participated. Students received treatment with…

The current study examined five- and seven-year-old Mandarin-speaking children's processing of lexical tones in relation to speech segments by varying onset and rime in an oddity task (onset±rime±). Results showed that children experienced more difficulty in lexical tone oddity judgment when rimes differed across monosyllables (e.g.…

Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall,…

Congenital amusia is a lifelong disorder characterized by a difficulty in perceiving and producing music despite normal intelligence and hearing. Behavioral data have indicated that it originates from a deficit in fine-grained pitch discrimination, and is expressed by the absence of a P3b event-related brain response for pitch differences smaller…

The study of definite descriptions has been a central part of research in linguistics and philosophy of language since Russell's seminal work "On Denoting" (Russell 1905). In that work Russell quickly dispatches analyses of denoting expressions with forms like "no man," "some man," "a man," and "every…

This dissertation examines two information-structural phenomena, Givenness and Focus, from the perspective of both syntax and pragmatics. Evidence from English, German and other languages suggests a "split" analysis of information structure--the notions of Focus and Givenness, often thought to be closely related, exist independently at…

This dissertation aims to extend our knowledge of prosody--in particular, what kinds of information may be conveyed through prosody, which prosodic dimensions may be used to convey them, and how individual speakers differ from one another in how they use prosody. Four production studies were conducted to examine how various factors interact with…

Duration-based auditory grouping preferences are presumably shaped by language experience in adults and infants, unlike intensity-based grouping that is governed by a universal bias of a loud-soft preference. It has been proposed that duration-based rhythmic grouping preferences develop as a function of native language phrasal prosody.…

In 3 experiments, we investigated whether intonational phrase structure can be primed. In all experiments, participants listened to sentences in which the presence and location of intonational phrase boundaries were manipulated such that the recording included either no intonational phrase boundaries, a boundary in a structurally dispreferred…

This dissertation is based on a long-term ethnographic and sociophonetic study of 15 transgender people on the female-to-male (or "transmasculine") identity spectrum. The focus of the study is the way these individuals' voices change during the first 1-2 years of masculinizing hormone therapy, which brings about a drop in vocal…

This dissertation proposes a model of word stress in a derivational version of Optimality Theory (OT) called Harmonic Serialism (HS; Prince and Smolensky 1993/2004, McCarthy 2000, 2006, 2010a). In this model, the metrical structure of a word is derived through a series of optimizations in which the "best" metrical foot is chosen…

Binaural hearing in cochlear implant (CI) users can be achieved either by bilateral implantation or bimodally with a contralateral hearing aid (HA). Binaural-bimodal hearing has the advantage of complementing the high-frequency electric information from the CI by low-frequency acoustic information from the HA. We examined the contribution of a…
