Book Synopsis Automatic Assessment of Prosody in Second Language Learning by : Florian Hönig
Download or read book Automatic Assessment of Prosody in Second Language Learning written by Florian Hönig and published by Logos Verlag Berlin GmbH. This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide there is a universal need for second language language learning. It is obvious that the computer can be a great help for this, especially when equipped with methods for automatically assessing the learner's pronunciation. While assessment of segmental pronunciation quality (i.,e. whether phones and words are pronounced correctly or not) is already available in commercial software packages, prosody (i.e. rhythm, word accent, etc.) is largely ignored--although it highly impacts intelligibility and listening effort. The present thesis contributes to closing this gap by developing and analyzing methods for automatically assessing the prosody of non-native speakers. We study the detection of word accent errors and the general assessment of the appropriateness of a speaker's rhythm. We propose a flexible, generic approach that is (a) very successful on these tasks, (b) competitive to other state-of-the-art result, and at the same time (c) flexible and easily adapted to new tasks.
Book Synopsis Second Language Prosody and Computer Modeling by : Okim Kang
Download or read book Second Language Prosody and Computer Modeling written by Okim Kang and published by Routledge. This book was released on 2021-09-13 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents an interdisciplinary approach to the study of second language prosody and computer modeling. It addresses the importance of prosody’s role in communication, bridging the gap between applied linguistics and computer science. The book illustrates the growing importance of the relationship between automated speech recognition systems and language learning assessment in light of new technologies and showcases how the study of prosody in this context in particular can offer innovative insights into the computerized process of natural discourse. The book offers detailed accounts of different methods of analysis and computer models used and demonstrates how these models can be applied to L2 discourse analysis toward predicting real-world language use. Kang, Johnson, and Kermad also use these frameworks as a jumping-off point from which to propose new models of second language prosody and future directions for prosodic computer modeling more generally. Making the case for the use of naturalistic data for real-world applications in empirical research, this volume will foster interdisciplinary dialogues across students and researchers in applied linguistics, speech communication, speech science, and computer engineering.

Book Synopsis Automatic Assessment of Children Speech to Support Language Learning by : Christian Hacker
Download or read book Automatic Assessment of Children Speech to Support Language Learning written by Christian Hacker and published by Logos Verlag Berlin GmbH. This book was released on 2009 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focus of this work are pattern recognition related aspects of computer assisted pronunciation training (CAPT) for second language learning. An overview of commercial systems shows that pronunciation training is being addressed by the growing field of computer assisted language learning only to a small extend, although in the state-of-the-art section a number of such approaches for automatic assessment can already be presented. In the present thesis different approaches are extended and combined. In particular a large set of nearly 200 pronunciation and prosodic features is developed. By this approach pronunciation scoring is regarded as classification task in high-dimensional feature space. Automatic speech recognition is the basis of most pronunciation scoring algorithms. In this thesis a system is presented, which supports second language learning at school, i.e. the target users are children. For this reason a state-of-the-art speech recognition engine is adapted to children speech, since young speakers are only hardly recognised by automatic systems. Phonetically motivated rules for typical mispronunciation errors are integrated into the system to make it suitable for pronunciation scoring. Evaluating an algorithm for pronunciation assessment is more difficult than simply counting the correctly recognised mistakes, since there exists no objective ground truth. This can be shown by evaluating the annotations of 14 teachers. However, with different measures it can be verified that the accuracy of the system (in comparison with teachers) thoroughly reaches the agreement among teachers. The evaluation is conducted with native German speakers learning English.

Book Synopsis Handbook of Second Language Assessment by : Dina Tsagari
Download or read book Handbook of Second Language Assessment written by Dina Tsagari and published by Walter de Gruyter GmbH & Co KG. This book was released on 2016-03-07 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Second language assessment is ubiquitous. It has found its way from education into questions about access to professions and migration. This volume focuses on the main debates and research advances in second language assessment in the last fifty years or so, showing the influence of linguistics, politics, philosophy, psychology, sociology, and psychometrics. There are four parts which, when taken together, address the principles and practices of second language assessment while considering its impact on society. Read separately, each part addresses a different aspect of the field. Part I deals with the conceptual foundations of second language assessment with chapters on the purposes of assessment, and standards and frameworks, as well as matters of scoring, quality assurance, and test validation. Part II addresses the theory and practice of assessing different second language skills including aspects like intercultural competence and fluency. Part III examines the challenges and opportunities of second language assessment in a range of contexts. In addition to chapters on second language assessment on a national scale, there are chapters on learning-oriented assessment, as well as the uses of second language assessment in the workplace and for migration. Part IV examines a selection of important issues in the field that deserve attention. These include the alignment of language examinations to external frameworks, the increasing use of technology to both deliver and score second language tests, the responsibilities associated with assessing test takers with special needs, the concept of 'voice' in second language assessment, and assessment literacy for teachers and other test and score users.
Book Synopsis 3D Trajectory Extraction from 2D Videos for Human Activity Analysis by : Zeyd Boukhers
Download or read book 3D Trajectory Extraction from 2D Videos for Human Activity Analysis written by Zeyd Boukhers and published by Logos Verlag Berlin GmbH. This book was released on 2017-11-26 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present dissertation addresses the problem of extracting 3D trajectories of objects from 2D videos. The reason of this is the theory that these trajectories symbolise high-level interpretations of human activities. A 3D trajectory of an object means its sequential positions in the real world over time. To this end, a generic framework for detecting objects and extracting their trajectories is proposed. In simpler terms, it means obtaining the 3D coordinate of the objects detected on the image plane and then tracking them in the real world to extract their 3D trajectories. Lastly, this dissertation presents applications of trajectory analysis to understand human activities in crowded environments. In this context, each phase in the framework represents independent approaches dedicated to solving challenging tasks in computer vision and multimedia.
Book Synopsis 3-D Imaging of Coronary Vessels Using C-arm CT by : Chris Schwemmer
Download or read book 3-D Imaging of Coronary Vessels Using C-arm CT written by Chris Schwemmer and published by Logos Verlag Berlin GmbH. This book was released on 2019-06-26 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular disease has become the number one cause of death worldwide. For the diagnosis and therapy of coronary artery disease, interventional C-arm-based fluoroscopy is an imaging method of choice. While these C-arm systems are also capable of rotating around the patient and thus allow a CT-like 3-D image reconstruction, their long rotation time of about five seconds leads to strong motion artefacts in 3-D coronary artery imaging. In this work, a novel method is introduced that is based on a 2-D-2-D image registration algorithm. It is embedded in an iterative algorithm for motion estimation and compensation and does not require any complex segmentation or user interaction. It is thus fully automatic, which is a very desirable feature for interventional applications. The method is evaluated on simulated and human clinical data. Overall, it could be shown that the method can be successfully applied to a large set of clinical data without user interaction or parameter changes, and with a high robustness against initial 3-D image quality, while delivering results that are at least up to the current state of the art, and better in many cases.
