Hidden structure refers to the units of organization that a child cannot directly observe when they are learning language (e.g. phonemes, morpheme boundaries, URs, phrases). In this dissertation, I propose a novel computational model that learns hidden structures in-tandem with the grammar. My model consists of two Maximum Entropy sub-models that…

Students need to know how to communicate succinctly. Often, students struggle to determine how much content is necessary to communicate a message. Designed for courses on public speaking, interpersonal communication, and organizational communication, this activity invites students to tell their class a story using a single sentence. After…

Introduction: Narratives are enriched by taking the perspective of the protagonists, which can be expressed using reported speech. Nevertheless, the use of reported speech is unaddressed internationally among individuals with Down syndrome. Method: Narratives of 28 children and adolescents with Down syndrome were collected using a non-verbal…

The prevalent "core phonological deficit" model of dyslexia proposes that the reading and spelling difficulties characterizing affected children stem from prior developmental difficulties in processing speech sound structure, for example, perceiving and identifying syllable stress patterns, syllables, rhymes and phonemes. Yet spoken word…

This study examined the effect of a serial multiple exemplar training (S-MET) procedure on bidirectional naming (BiN) in four preschool children diagnosed with autism spectrum disorder (ASD). A non-concurrent multiple baseline design was used to evaluate the effects of training listener and speaker behavior for one stimulus at a time until BiN…

Before you got into leadership, did you expect you'd be doing so much speaking? It seems you're always talking--in faculty meetings and one-on-one evaluations; in PD sessions and department meetings; at parents' night and awards ceremonies; to colleagues, supervisors, and the school board; and in front of dozens or hundreds or just a webcam and a…

Noise is a common impedance to easy and accurate speech understanding. In the presence of noise, speech processing mechanisms proceed with partial or ambiguous inputs, and listeners will engage additional cognitive resources to make sense of what they hear. The extent to which this is situation is affected by diminished exposure to a language is…

This conversation analytic study investigates the use of the Japanese contrastive marker "demo" "but" as a preface to responses to polar questions. "Demo"-prefaced responses are one type of nonconforming answers, that is, responses that provide (dis)affirmation to preceding questions without yes/no-tokens. This study…

Generalization in motor control is the extent to which motor learning affects movements in situations different than those in which it originally occurred. Recent data on orofacial speech movements indicates that motor sequence learning generalizes to novel syllable sequences containing phonotactically illegal, but previously practiced, consonant…

To learn the meaning of a new word, or to recognize the meaning of a known one, both children and adults benefit from surrounding words, or the sentential context. Most of the evidence from children is based on their accuracy and efficiency when listening to speech in their familiar native accent: they successfully use the words they know to…

People with aphasia may produce speech errors or pauses during speaking turns. A communication partner may choose to guess the person's intended meaning, or may allow the person time to repair their turns (i.e., edited turns). The aim of this study was to understand the topic-related effects that occur when speakers without aphasia allow their…

Computational models of infant word-finding typically operate over transcriptions of infant-directed speech corpora. It is now possible to test models of word segmentation on speech materials, rather than transcriptions of speech. We propose that such modeling efforts be conducted over the speech of the experimental stimuli used in studies…

Purpose: This qualitative study examines autistic adolescents' perception of the quality of their relationship with their parent using the Three Minute Speech Sample. Methods: Twenty autistic youth (13-17 years; 83% male) spoke, uninterrupted, for three minutes about their thoughts and feelings regarding their mothers. Audio-recorded speech…

The revised Speech Learning Model (SLM-r) postulates that learners with more precisely defined categories in their native language (L1) exhibit greater proficiency in acquiring sounds in a second language (L2). Despite its recent emergence, empirical studies validating this hypothesis remain scarce. This study aims to investigate the predictive…

We examined the use of filled pauses in conversations between homogeneous pairs of autistic and non-autistic adults. A corpus of semi-spontaneous speech was used to analyse the rate, lexical type (nasal "uhm" or non-nasal "uh"), and prosodic realisation (rising, level or falling) of filled pauses. We used Bayesian modelling for…
