Slow Electroencephalographic Changes Preceding Speech Production

Articulatory Speech Synthesis and Speech Production Modelling
… work, we carefully argue that the articulatory speech production model has the potential to flexibly synthesize natural-quality speech sounds and to provide a compact computational model for speech production that can be beneficial to a wide range of areas in speech signal processing.

Syntactic control of timing in speech production.

Velopharyngeal Function During Speech Production of Older Adults
… of aging on velopharyngeal function during speech production was studied. Six normal younger adults (20-40 years of age) and six older adults (80+ years of age) were asked to produce consonant-vowel syllable repetitions, as well as word and sentence repetitions containing abutting nasal-oral …

Speech Production and Developmental Language Disorder in Children
… (AE) and rise time in the perception and production of stress patterns, instead focusing on other parameters. My thesis will fill this gap, focusing on relations between AE processing as measured by 3 psychoacoustic tasks and the production of syllable stress patterns. Additionally, I will …

Respiratory constraints on speech production at prosodic boundaries
… within the utterance were also collected. For speech boundaries th.i.t are aligned with breath boundaries, utterance initiation occurs during a rapid transition in muscular effort. Sound begins as soon as conditions permit and these conditions consistently occur during net inspiratory muscular …

Neural representations used by brain regions underlying speech production
Speech utterances are phoneme sequences but may not always be represented as such in the brain. For instance, electropalatography evidence indicates that as speaking rate increases, gestures within syllables are manipulated separately but those within consonant clusters act as one motor unit. …

An algorithm for characterizing context-governed speech production patterns
Speech recognition and analysis can be improved by using methods that can effectively characterize important speech patterns of a speaker without requiring hours of data. This thesis defines a method by which key contexts related to systematic speech modification can be used to create a profile of …

Speech Production Effects on Word Learning and Memorization in Children
In this dissertation, I explore the impact of speech production on memory and learning in children, by investigating the Production Effect and the Reverse Production Effect. In the Production Effect, a memory advantage is observed for items that are produced aloud compared to items studied under …

Immediate transfer of learning from speech perception to speech production
… later perception (Onishi et al., 2002), and speech production errors reflect constraints present in recently spoken syllables (Dell et al., 2000). There is little evidence, however, that such phonotactic learning can transfer between perception and production (Warker et al., 2009). In three …

A physiologically-oriented model of tongue activity in speech production.

Assessing functional links between speech production and perception in multilingual speakers
The relationship between speech production and speech perception capacities is highly debated. The picture is complicated further by studies of second language acquisition, where development of speech perception is not always accompanied by proportional gains in speech production, and vice versa. …

Incremental lexical learning in speech production: a computational model and empirical evaluation
… way that words are activated and selected for production, and some have claimed that the findings are only understandable by positing a competitive mechanism for lexical selection. This dissertation presents and evaluates a simple model of lexical retrieval in speech production that applies …

Modeling temporal coordination in speech production using an artificial central pattern generator neural network
… formal and biologically plausible models of the speech production and planning system. Models based on oscillators have been successful in simulating gestural dynamics, and more recently, some suprasegmental timing patterns. This dissertation explores how different levels of phonological …

Visualizing speech production with a hidden Markov model tracker to aid speech therapy and communication
… can range from problems in comprehension of speech to expression of speech to the point that it interferes with an individuals achievement and/or quality of life. Communication disorders can compromise a persons psychological, sociological, educational and vocational growth. There have been …

Is comprehension necessary for error detection? A conflict-based account of monitoring in speech production
Although speech is error-prone, verbal communication is successful because speakers can detect (and correct) their errors. The standard theory of speech-error detection, the perceptual-loop account, posits that the comprehension system monitors production output for errors. Such a …

Laryngeal function associated with changes in lung volume during voice and speech production in normal speaking women
… the patterns of change were similar for both speech tasks. Individual subject data reflected alternative patterns of laryngeal behavior for achieving the speech tasks. The results were interpreted as evidence that laryngeal function during voice production is clearly influenced by the lung …

The Interaction of *Focus and Lexical Pitch Accent in Speech Production and Dialogue Comprehension: Evidence From Japanese and Basque
… shape of words is lexically determined. Two production experiments were conducted to examine how speakers of these two languages manipulate pitch to express various types of focal status of words in pre-determined experimental dialogues. In the first experiment, both Tokyo Japanese and Bermeo …

When life gives you lemons, make a left: Investigation of contextualization of learning in speech production using speech errors
Language production is a flexible yet complex system and is constantly updated by new experience. Within this system, implicit phonotactic learning provides a window into how speakers acquire and generalize rules that govern sound patterns. This thesis investigates how such rules are represented, …
