The Xitsonga murmured speech sounds and their representations in the Xitsonga orthography
… symbols of languages represent specific speech sounds with their specific phonetic qualities. This research aimed at analysing orthographic representations of murmured speech sounds in the Xitsonga orthography. The qualitative approach was employed to examine the production of murmured …

Effects of microphone type and distance upon the spectra of speech sounds
Thesis (S.B. and M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 1999.

The Representation of Normally-Voiced and Whispered Speech Sounds in the Temporal Aspects of Auditory Nerve Responses
Whispered and normally-voiced speech sounds were encoded by distinct patterns in the AN, when responses of all fibers were included. These common representations support and describe auditory mechanisms for speech perception.

Effects of Visual Feedback on the Production and Perception of Second Language Speech Sounds : A Comparison of Articulatory and Auditory Instruction
A fundamental issue in speech science concerns the extent to which speech sounds are mentally represented by articulatory-motor and/or auditory-acoustic features. This dissertation aims to expand upon the current literature by investigating changes in production and perception following visual …

Graphical and Non-speech Sound Metaphors in Email Browsing: An Empirical Approach. A Usability Based Study Investigating the Role of Incorporating Visual and Non-Speech Sound Metaphors to Communicate Email Data and Threads.
… information visualisation techniques and non-speech sounds (i.e. auditory icons and earcons) in email browsing. This empirical work consisted of three experimental phases. The first experimental phase aimed at finding out the most usable visualisation techniques for presenting email …

A translation framework for discovering word-like units from visual scenes and spoken descriptions
… each co-occur with a particular sequence of speech sounds, we can infer that those speech sounds are a word whose definition is the visible object. A multimodal word discovery system accepts, as input, a database of spoken descriptions of images (or a set of corresponding phone …

Encouraging the expression of the unspeakable : influence and agency in a robotic creature
… unspoken experience through the making of non-speech sounds and we have a situation that demands new thoughts and new methodologies. This thesis works through these questions via the design and study of syngvab, a robotic marionette that moves in response to human non-speech vocal sounds. I …

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.

Accuracy Of Parental Report On Phonological Inventories Of Toddlers
… of information. In this study, the Survey of Speech Development (SSD) (Perry-Carson & Steel, 2001; Steel, 2000) was used to determine the accuracy of parents in reporting the speech sound inventories of their toddlers. Parents of 30 children, who were between the ages of 27 to 33 months old, …

Removing redundancy in speech by modeling forward masking
… approaches to this, the first being automatic speech recognition (ASR). Even though many state-of-the-art analysis methods, such as LPC, STFT, and MFCC, have been used in speech recognition, the performance of ASR has reached a plateau and the speech decoding problem remains unresolved. …

Who is that talking? Function and dysfunction of efference copy and corollary discharge in healthy people and schizophrenic patients
… influences the neural responses to self produced speech sounds when they either match their internal predictions or when they are externally (experimentally) altered and do not match. The results show that the N100 event-related response measured using Electroencephalography was most suppressed …

Cardiovascular Reactivity to Speech Processing and Cold Pressor Stress: Evidence for Sex Differences in Dynamic Functional Cerebral Laterality
… increased significantly when focusing on sounds presented at the left ear during the dichotic listening task. Also, a compartmentalized, dynamic response in dichotic listening test performance was evidenced in both men and women (as both experienced increased accuracy at the right, but not …

Articulation in brass playing : the tongue - friend or foe?
… the tongue's position in producing English speech sounds. It shows how these positions are used to teach different articulation techniques on the various brass instruments. Articulation styles and (tonguing) exercises, which could aid in the improvement of tongue articulation, are …

Improving broadcast accessibility for hard of hearing individuals : using object-based audio personalisation and narrative importance
… identifying the personalisation of redundant non-speech objects as a potentially high impact yet unexplored area of research. Guided by these findings, and the results of a survey of end-user needs, the specific research questions of this work are then developed as:- What is the relationship …

Speech Representation Models for Speech Synthesis and Multimodal Speech Recognition
The field of speech recognition has seen steady advances over the last two decades, leading to the accurate, real-time recognition systems available on mobile phones today. In this thesis, I apply speech modeling techniques developed for recognition to two other speech problems: speech synthesis …

The Effects of a Humanoid Robot's Non-lexical Vocalization on Emotion Recognition and Robot Perception
… has been conducted on conveying emotions via speech, whereas little research has focused on the effects of non-speech sounds on users' robot perception. We conducted a within-subjects exploratory study with 40 young adults to investigate the effects of non-speech sounds (regular voice, …
