Exploring the influence of suprasegmental features of speech on rater judgements of intelligibility

A thesis submitted to the University of Bedfordshire in partial fulfilment of the requirements for the degree of Doctor of PhilosophyThe importance of suprasegmental features of speech to pronunciation proficiency is well known, yet limited research has been undertaken to identify how raters attend to suprasegmental features in the English-language speaking test encounter. Currently, such features appear to be underrepresented in language learning frameworks and are not always satisfactorily incorporated into the analytical rating scales that are used by major language testing organisations. This thesis explores the influence of lexical stress, rhythm and intonation on rater decision making in order to provide insight into their proper place in rating scales and frameworks. Data were collected from 30 raters, half of whom were experienced professional raters and half of whom lacked rater training and a background in language learning or teaching. The raters were initially asked to score 12 test taker performances using a 9-point intelligibility scale. The performances were taken from the long turn of Cambridge English Main Suite exams and were selected on the basis of the inclusion of a range of notable suprasegmental features. Following scoring, the raters took part in a stimulated recall procedure to report the features that influenced their decisions. The resulting scores were quantitatively analysed using many-facet Rasch measurement analysis. Transcriptions of the verbal reports were analysed using qualitative methods. Finally, an integrated analysis of the quantitative and qualitative data was undertaken to develop a series of suprasegmental rating scale descriptors. The results showed that experienced raters do appear to attend to specific suprasegmental features in a reliable way, and that their decisions have a great deal in common with the way non-experienced raters regard such features. This indicates that stress, rhythm, and intonation may be somewhat underrepresented on current speaking proficiency scales and frameworks. The study concludes with the presentation of a series of suprasegmental rating scale descriptors

From Orators to Cyborgs: The Evolution of Delivery, Performativity, and Gender

@font-face { font-family: Cambria ; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: Times New Roman ; }div.Section1 { page: Section1; } The purpose of this project is to provide a thorough account of delivery by tracing the history and evolution of delivery from antiquity to the present day in order to expose the spread and transmission of proto-masculine ideologies through delivery. By looking at delivery from an evolutionary perspective, delivery no longer becomes a tool of rhetoric, but the technology of rhetoric, evolving over time in the same way the system of rhetoric itself has evolved. Contemporary scholarship on delivery continues to look at delivery as a tool—as the ink, the paper, the computer screen, the keyboard, the font, the hypertext, the web design, and so forth—of communication. Contemporary scholarship re-works the classical definition of delivery to fit into a contemporary context, and consequently ignores the proto-masculinity embedded into classical delivery and its spread from public speaking to all speaking situations—and the larger consequence of this approach is that proto-masculinity remains embedded and idealized. Focusing specifically on delivery’s history and evolution into a post-human, cyborg technology demonstrates how proto-masculinity has operated within delivery and how proto-masculinity has been spread through delivery instruction. The importance of re-situating delivery within the rhetorical canons affects rhetoric as a whole because it demonstrates that not only is delivery still crucial to rhetoric, and possibly still the most important rhetorical canon, but also because it de-naturalizes the proto-masculine imperatives embedded within delivery and conveyed through delivered language performances

Models and Analysis of Vocal Emissions for Biomedical Applications

The International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA) came into being in 1999 from the particularly felt need of sharing know-how, objectives and results between areas that until then seemed quite distinct such as bioengineering, medicine and singing. MAVEBA deals with all aspects concerning the study of the human voice with applications ranging from the newborn to the adult and elderly. Over the years the initial issues have grown and spread also in other fields of research such as occupational voice disorders, neurology, rehabilitation, image and video analysis. MAVEBA takes place every two years in Firenze, Italy. This edition celebrates twenty-two years of uninterrupted and successful research in the field of voice analysis

Language technologies in speech-enabled second language learning games : from reading to dialogue

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2012.Cataloged from PDF version of thesis.Includes bibliographical references (p. 237-244).Second language learning has become an important societal need over the past decades. Given that the number of language teachers is far below demand, computer-aided language learning software is becoming a promising supplement to traditional classroom learning, as well as potentially enabling new opportunities for self-learning. The use of speech technologies is especially attractive to offer students unlimited chances for speaking exercises. To create helpful and intelligent speaking exercises on a computer, it is necessary for the computer to not only recognize the acoustics, but also to understand the meaning and give appropriate responses. Nevertheless, most existing speech-enabled language learning software focuses only on speech recognition and pronunciation training. Very few have emphasized exercising the student's composition and comprehension abilities and adopting language technologies to enable free-form conversation emulating a real human tutor. This thesis investigates the critical functionalities of a computer-aided language learning system, and presents a generic framework as well as various language- and domain-independent modules to enable building complex speech-based language learning systems. Four games have been designed and implemented using the framework and the modules to demonstrate their usability and flexibility, where dynamic content creation, automatic assessment, and automatic assistance are emphasized. The four games, reading, translation, question-answering and dialogue, offer different activities with gradually increasing difficulty, and involve a wide range of language processing techniques, such as language understanding, language generation, question generation, context resolution, dialogue management and user simulation. User studies with real subjects show that the systems were well received and judged to be helpful.by Yushi Xu.Ph.D

Attitudes towards Finnish-accented English

The thesis opens with a discussion of what attitudes are, and develops with a review of studies of attitudes towards pronunciation error, attitudes towards foreign accents and perception of foreign-accented speakers. The empirical part of the thesis attempts to identify how native (British) and Finnish listeners of English react to and evaluate typical segmental features of mispronunciation in the English speech of Finnish men and women of various ages. Two experiments using modifications of the matched-guise technique were conducted, one to consider error evaluation and to establish a hierarchy of segmental mispronunciation, the other to examine speaker evaluation, the image of the speaker created by the mispronunciation. Recordings of Finnish-accented English were presented to male and female listeners of various ages, and reactions collected. Statistical analyses of the results were carried out and the following general conclusions were drawn: the English labiodental lenis fricative /v/ when mispronounced in the typical Finnish manner as a labiodental frictionless continuant [u] is not tolerated by native English listeners at all, though it is highly tolerated by Finnish-speaking listeners (and Swedish-speaking Finns) themselves; the degree of mispronunciation in Finnish-accented English seriously affects listeners' estimations of the speaker's age, bad mispronunciation prompting under-estimation of age and good pronunciation over-estimation; both Finnish-speaking listeners and English-speaking listeners have almost identical clear pre-set standards about what constitutes `good' and `bad' pronunciation; a Finnish speaker's phonemically `better' and `worse' pronunciation affects the image listeners have of the speaker, status/competence traits in particular being up-graded for better pronunciation, solidarity/benevolence traits remaining broadly unaffected, and Englishspeaking listeners generally being more positive towards the Finnish-accented speakers than compatriot Finns

Language Fluency Project: An Investigation Into the Training and Development of Socialised Language With Adolescents With a Mental Handicap

Since the publication of the Warnock Report (1978) on children's special educational needs, special schooling has taken a new direction. Some authorities have even gone as far as to abolish their special schools, while others have implemented greater integration between special and ordinary schools. In almost all instances a greater challenge has been given to children hitherto labelled as handicapped, either physically or mentally, or both. They are now expected to cope in a greater variety of educational settings. Such demands highlight the need for more action research in the social and communication skills of persons of all ages with a mental handicap. The Language Fluency Project, hereafter referred to as LFP, was set up to investigate the development and training of socialised language in adolescents with a mental handicap, their linguistic behaviour in a conversation situation, and the development of verbal and social facility
