Prosodic Marking Of Focus In Autistic And Neurotypical Adults, Nishtha N. Trivedi

Dissertations, Theses, and Capstone Projects

Purpose: This study investigates how adult autistic speakers compare with neurotypical speakers in the manipulation of prosody to mark narrow and contrastive focus in American English. In particular, it explores whether the two groups differ in terms of pitch accent status, pitch accent type, and overall nuclear contour patterns in focus marking.

Methods: We conducted an experiment eliciting speech from autistic and neurotypical adults in which we compared their use of pitch accent in answers to wh-questions and in corrective statements.

Results: We found neurotypical speakers to primarily use H* to mark narrow focus on subjects and L+H* to mark …

Lexical Stress Realization In Mandarin Second Language Learners Of English: An Acoustic And Articulatory Study, Boram Kim

Dissertations, Theses, and Capstone Projects

This dissertation investigated the acoustic and articulatory correlates of lexical stress in Mandarin second language (L2) learners of English, as well as in first language (L1) speakers. The present study used a minimal pair respective to stress location (e.g., OBject versus obJECT) obtained from a publicly available Mandarin Accented English Electromagnetic articulography corpus dataset. In the acoustic domain, the use of acoustic parameters (duration, intensity, F0, and vowel quality) was measured in stressed and unstressed vowels. In the articulatory domain, the positional information from tongue tip (TT), tongue dorsum (TD), upper lip (UL), lower lip (LL), and jaw (JAW) were …

Prosody And Intonation In Formosan Languages, Benjamin K. Macaulay

Dissertations, Theses, and Capstone Projects

The Formosan languages are the languages of the Aboriginal peoples of Taiwan. These languages are part of the Austronesian language family, and represent all but one primary branch of this family of 1,200+ languages. The Formosan languages are endangered, some critically so. While these languages have seen attention in the literature for their syntactic and phonological systems, little work has been done on their prosodic structure or intonation.

This dissertation analyzes the prosodic structure and intonational phonology of Mantauran Rukai, Budai Rukai, Tsou, Kanakanavu, Hla’alua, Sandimen Paiwan, Piuma Paiwan, Kavalan, Amis, Bunun, Tgdaya Seediq, Truku Seediq, and Pazeh, based on …

Musical Ability And Accent Imitation, Maria Murljacic

Honors Scholar Theses

This study investigates the intersection of musical ability and accent imitation, more specifically defining what factors cause a relationship between the two. The study was run on 50 participants, who each completed an accent imitation ability assessment, a musical ability assessment, and an articulation ability assessment. The scores for the accent imitation portion were rated by anonymous online raters. Each participant filled out a questionnaire on prior musical experience and were either classified as a musician or non-musician. The analysis found that those in the musician group performed better on the musical ability, articulation, and accent ability assessment than non-musicians. …

Prepositional Phrase Attachment Ambiguities In Declarative And Interrogative Contexts: Oral Reading Data, Tyler J. Peckenpaugh

Dissertations, Theses, and Capstone Projects

Certain English sentences containing multiple prepositional phrases (e.g., She had planned to cram the paperwork in the drawer into her briefcase) have been reported to be prone to mis-parsing of a kind that is standardly called a “garden path.” The mis-parse stems from the temporary ambiguity of the first prepositional phrase (PP1: in the drawer), which tends to be interpreted initially as the goal argument of the verb cram. If the sentence ended there, that would be correct. But that analysis is overridden when the second prepositional phrase (PP2: into her briefcase) is encountered, since the …

The Interaction Of Domain-Initial Effects With Lexical Stress: Acoustic Data From English, Spanish, And Portuguese, Ricardo F. Napoleão De Souza

Linguistics ETDs

The phonetic implementation of domain-initial boundaries has gained considerable attention in the literature. However, most studies of the phenomenon have investigated small samples of articulatory data in which target syllables were lexically prominent and/or phrasally accented, introducing important potential confounds. This dissertation tackles these issues by examining how domain-initial effects operate on the acoustic properties of fully unstressed word-initial CV syllables in phrasally unaccented words. Similar materials were designed for a reading task in which 14 speakers of English, Spanish and Portuguese, languages that differ in how lexical prominence affects segmental makeup, took part. Results from the acoustic analyses show …

L2 Learners And The Intelligiblity Of The Bostonian And Californian Accents, Russell Paul Kapryn

Electronic Theses, Projects, and Dissertations

This thesis investigates issues of intelligibility through the lens and focus of prosody when the Bostonian and Los Angeles-based accents are heard in casually occurring conversation by native and non-native speakers. Over the spring and summer of 2017, six native speakers and 11 non-native speakers of English were interviewed from having listened to two 2.5 minute audio sample clips of speakers who have these accents. Respondents were asked questions such as what was difficult or easy or whether they could summarize the recordings for me. Findings indicate that while the native speakers often had difficulty with vocabulary due to context, …

Investigating Prosodic Accommodation In Clinical Interviews With Depressed Patients, Brian Vaughan, Carolina De Pasquale, Lorna Wilson, Charlie Cullen, Brian Lawlor

Conference Papers

Six in-depth clinical interviews, involving six elderly female patients (aged 60+) and one female psychiatrist, were recorded and analysed for a number of prosodic accommodation variables.

Our analysis focused on pitch, speaking time, and vowel-space ratio. Findings indicate that there is a dynamic manifestation of prosodic accommodation over the course of the interactions. There is clear adaptation on the part of the psychiatrist, even going so far as to have a reduced vowel-space ratio, mirroring a reduced vowel-space ratio in the depressed patients. Previous research has found a reduced vowel-space ratio to be associated with psychological distress; however, we suggest …

Cuasi Nomás Inglés: Prosody At The Crossroads Of Spanish And English In 20th Century New Mexico, Jackelyn Van Buren

Linguistics ETDs

This dissertation investigates prosodic change in the long-term language contact setting of Traditional New Mexican Spanish (NMS). NMS prosody is perceptually distinct from other contemporary varieties of Spanish (Hills 1906, Bowen 1952, Lipski 2011), yet the features which make it unique have not been acoustically examined. This study hypothesizes that bilingualism with English has affected NMS prosody and analyzes three features which are known to differ between Spanish and English and therefore provide a quantitative point of comparison: pitch peak alignment, pitch variability, and rhythmic timing. These variables have been demonstrated to be susceptible to transfer in contact situations, including …

Acoustic Classification Of Focus: On The Web And In The Lab, Jonathan Howell, Mats Rooth, Michael Wagner

Department of Linguistics Faculty Scholarship and Creative Works

We present a new methodological approach which combines both naturally-occurring speech harvested on the web and speech data elicited in the laboratory. This proof-of-concept study examines the phenomenon of focus sensitivity in English, in which the interpretation of particular grammatical constructions (e.g., the comparative) is sensitive to the location of prosodic prominence. Machine learning algorithms (support vector machines and linear discriminant analysis) and human perception experiments are used to cross-validate the web-harvested and lab-elicited speech. Results con rm the theoretical predictions for location of prominence in comparative clauses and the advantages using both web-harvested and lab-elicited speech. The most robust …

Relationship Between Acoustic Measures And Speech Naturalness Ratings In Parkinson’S Disease: A Within-Speaker Approach, Marie I. Klopfenstein

SIUE Faculty Research, Scholarship, and Creative Activity

This study investigated the acoustic basis of across-utterance, within-speaker variation in speech naturalness for four speakers with dysarthria secondary to Parkinson’s disease (PD). Speakers read sentences and produced spontaneous speech. Acoustic measures of fundamental frequency, phrase-final syllable lengthening, intensity and speech rate were obtained. A group of listeners judged speech naturalness using a nine-point Likert scale. Relationships between judgements of speech naturalness and acoustic measures were determined for individual speakers with PD. Relationships among acoustic measures also were quantified. Despite variability between speakers, measures of mean F0, intensity range, articulation rate, average syllable duration, duration of final syllables, vocalic nucleus …

Implications Of Autosegmental Analysis In The Exploration Of Prosodic Phonology In Mandarin Chinese, Kristen Frazier

Senior Honors Theses

Autosegmental Phonology (Goldsmith, 1979) is a theoretical framework for understanding the phonological effects of suprasegmentals such as tone, stress, etc. Using data taken from an experiment in which Mandarin Chinese tone sandhi (the acknowledged rules governing specific tone shifts across segments) is explored, a number of phonologists, specifically Kenstowicz (2003), have shown that the relationship between the segment and the tone is autonomous. In the experiment, non-sense words with a potential tone sandhi rule are presented to the Mandarin speakers. The speakers automatically apply the tone sandhi rule which is then analyzed using an autosegmental framework. The speakers consciously separate …

Prosody-Based Query-By-Example Spoken Utterance Retrieval, Steven D. Werner, Nigel G. Ward

COURI Symposium Abstracts, Summer 2012

Current spoken dialogue retrieval systems are almost entirely lexically based, using automatic transcription by imperfect speech recognition technology. Once audio is reduced to text, little more than existing text search methods are used to retrieve results. However, spoken dialogue contains rich latent prosodic information about dialogue activities - such as agreeing, arguing, deciding, planning, storytelling, showing surprise - and this extra information can often be relevant to the searchers aims. Searching for similar speech acts rather then similar words enables similar contextual results, returning points where the speaker had the same sentiment during a topic. Previous research yielded 76 dimensions …

Prosodylab-Aligner: A Tool For Forced Alignment Of Laboratory Speech, Kyle Gorman, Jonathan Howell, Michael Wagner

Department of Linguistics Faculty Scholarship and Creative Works

The Penn Forced Aligner automates the alignment process using the Hidden Markov Model Toolkit (HTK). The core of Prosodylab-Aligner is align.py, a script which performs acoustic model training and alignment. This script automates calls to HTK and SoX, an open-source command-line tool which is capable of resampling audio. The included README file provides instructions for installing HTK and SoX on Linux and Mac OS X, and can also be run on Windows. During training, the model is initialized with flat-start monophones, which are then submitted to a single round of model estimation. Then, a tied-state 'small pause' model is inserted …

The Effect Of Learning On Sentence Prosody In Japanese, Joanna Baldwin Clark

Linguistics Honors Projects

This study investigates the effect of learning on prosodic production competence in native English L2 speakers of Japanese. Intonation contour and speech rate as indicators of competency were examined. It was hypothesized that more experience with Japanese would lead to more native-like prosody. The study tested the production of fourteen L2 learners, ten non-learners and six native speakers. Participants recorded twenty-three sentences of Japanese. Acoustic data was analyzed for speech rate and fundamental frequency (F0). Results showed that experience is positively correlated with speech rate and not correlated with deviation from the Japanese mean intonation contour.

Measuring Variations Of Mimicry By Means Of Prosodic Cues In Task-Based Scenarios And Conversational Speech, Brian Vaughan, Celine De Looze

Other resources

Here, we address the measurement of mimicry, that is when speakers’ speech variations look like parallel patterns.

As a definition of mimicry, we often read in the literature description such as mimicry is “The situation where the observed behaviours of two inter-actants although dissimilar at the start of the interaction are moving towards behavioral matching”. These types of descriptions imply that mimicry is a linear phenomenon and that speakers tend to imitate over time. However, it can be assumed, especially when studying spontaneous speech, that there are rather phases of mimicry and non-mimicry and that mimicry should be rather …

Second Occurrence Focus And The Acoustics Of Prominence, Jonathan Howell

Department of Linguistics Faculty Scholarship and Creative Works

Partee (1991) challenged the significance of the observation that certain adverbs (e.g., only) reliably associate with phonologically prominent words to truth‐conditional effect, noting second occurrence (i.e., repeated or given) focus (SOF) appears to lack a phonological realization. Rooth (1996), Bartels (2004), Beaver et al. (2004), Jaeger (2004), and Fry and Ishihara (2005) argued that, while not intonationally prominent, an SOF word can be marked by increased duration and/or increased rms intensity. An acoustic study of verb‐noun homophone pairs is reported. Three sophisticated speakers uttered five repetitions of the targets, embedded in discourses, in first occurrence (FOF), SOF, and unfocused (NF) …

Linguistic Rhythm And Grammatical Structure In Afghan Persian, Janet Mueller Bing

English Faculty Publications

Afghan Persian has a rhythm rule that shifts a strong stress to the left when it occurs near another strong stress. Metrical theory (see LLBA 12/1, 7800555) states this shift as a change in the configuration of hierarchical values where the relationships "stronger than" & "weaker than" apply not only to adjacent syllables, but also to groups of syllables, words, & phrases. This rule accounts for the differences in stress patterns on words in isolation & in some phrases. By assuming the rhythm rule & a rule of stress assignment, it is possible to account for both word & phrasal …
