This book was released on 2011-04 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of mathematical methods for analyzing pathological speech signals is one of the best approaches to non-invasive diagnosis of laryngeal dysfunctions in patients with vocal fold disorders. The processing of disordered voice signals is a useful technique that provides a low-cost and time-efficient clinical tool for automatic detection of neurological and physical damages to the vocal folds. The application of these methods can help speech pathologists routinely monitor the functionality of patients' speech production system and provide them with appropriate therapies, medication or treatments. Moreover, these method can help detect the early symptoms and prevent the progress of some severe types of these diseases (e.g. laryngeal cancer) by tracking changes in the acoustical parameters of a patients' voice. In this book, a variety of signal processing methods are proposed, implemented and discussed with relevance to the diagnosis of different types of laryngeal diseases. The discussed methods include classical and novel signal processing approaches to the diagnosis of laryngeal diseases with specific focus on vocal fold disorders in patients with pathological speech.

Available in PDF, EPUB and Kindle. Book excerpt: Digital imaging and signal analysis are extremely useful in the diagnosis and study of voice disorders. When a microphone captures the voice, an acoustic signal can be produced and stored on a computer. The distinct signal pattern is an excellent indication of the quality of voice, and can be used to compare deviant voices with healthy voices. This study focuses on a computer analysis of laryngeal function-specifically on the acoustic analysis of vocal fold vibration in normal subjects and patients with specific voice disorders. The vocal pattern of each patient is analyzed using the MatLab computer program, producing a graph showing the unique vocal pattern for each patient. The acoustic recording of the vocal signal is observed, along with the analysis using fast Fourier Transform and short Fourier Transform. The patterns of many voice disorders are compared, including those in patients with vocal fold scarring and vocal fold cysts. A comparison is then made between the patterns of patients with a "normal" voice and those with the specified disorders. A brief introduction to the laryngeal image based analysis of glottal waveform is included, and compared with acoustic analysis results.

Download or read book Computing PROSODY written by Yoshinori Sagisaka and published by Springer. This book was released on 2011-09-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a collection of papers from the Spring 1995 Work shop on Computational Approaches to Processing the Prosody of Spon taneous Speech, hosted by the ATR Interpreting Telecommunications Re search Laboratories in Kyoto, Japan. The workshop brought together lead ing researchers in the fields of speech and signal processing, electrical en gineering, psychology, and linguistics, to discuss aspects of spontaneous speech prosody and to suggest approaches to its computational analysis and modelling. The book is divided into four sections. Part I gives an overview and theoretical background to the nature of spontaneous speech, differentiating it from the lab-speech that has been the focus of so many earlier analyses. Part II focuses on the prosodic features of discourse and the structure of the spoken message, Part ilIon the generation and modelling of prosody for computer speech synthesis. Part IV discusses how prosodic information can be used in the context of automatic speech recognition. Each section of the book starts with an invited overview paper to situate the chapters in the context of current research. We feel that this collection of papers offers interesting insights into the scope and nature of the problems concerned with the computational analysis and modelling of real spontaneous speech, and expect that these works will not only form the basis of further developments in each field but also merge to form an integrated computational model of prosody for a better understanding of human processing of the complex interactions of the speech chain.

Download or read book Computational Agent based Modeling of Surgical Vocal Fold Injury and Repair written by Aman Garg and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Voice disorders affect about one in ten adults at some point in their lifetime. Vocal fold scarring can result from surgical excision of benign and malignant vocal fold lesions. The elicited inflammation and healing response is complex and dynamic. It involves immune and repair cells (e.g., neutrophils, macrophages, fibroblasts) and molecules (e.g., inflammatory cytokines, damage-associated molecular pattern molecules) to locate damaged tissue, eliminate the necrotic cells and debris, and produce extracellular matrix substances for eventual tissue repair. A mechanistic understanding of the vocal fold injury and repair process will help in identifying the effective treatments for iatrogenic vocal fold scarring from surgery.The overall goal of this thesis was to develop computational agent-based models (ABM) that could numerically simulate the dynamics of major cellular and molecular components involved in surgical vocal fold injury and repair. The first research goal was to phenotype and enumerate immune and repair cells in surgically injured rat vocal folds up to 4 weeks after surgical injury. Viable cells were isolated from harvested vocal folds and were stained for cell surface markers specific to neutrophils, macrophages, endothelial cells and fibroblasts. Multi-parametric flow cytometry was then conducted to count the number of cells for each cell population in the vocal fold samples. The second research goal was to calibrate and validate existing agent-based models of vocal fold injury and repair (VF-ABM) with the flow cytometry data. Global sensitive analysis using Random Forests were first employed to identify the most influential model parameters on the outputs of cell numbers. The Robust Parameter Estimation (ROPE) algorithm from the package of Statistical Parameter Optimization Tool for Python (SPOTPY) was then used to calibrate VF-ABM for early time points from Day 1 to Day 5 of the flow cytometry data. Subsequently, VF-ABM were run 100 times to generate 95% confidence intervals for model evaluation. VF-ABM predicted outputs were considered accurate if the empirical data points were within the 95% confidence intervals of simulated outputs. Cell population quantities were calculated for Day 7, Week 2 and Week 4 respectively against the empirical flow cytometry data. Predicted cell populations reached 100% accuracy for Day 7. Although VF-ABM generated qualitative trends of cell population comparable to those of Weeks 2 and 4, the corresponding empirical data values fell outside of the 95% confidence intervals. Results from the flow cytometry study provided quantitative and time-dependent data on major cell populations involved in surgical vocal fold injury. Results from the model verification informed the area of improvements for the next generation of VF-ABM. This thesis contributes to the development of a computational tool that would better inform clinicians in prescribing treatments for patients with voice disorders." --

Download or read book Analysis of Speech of People with Parkinson s Disease written by Juan Rafael Orozco-Arroyave and published by Logos Verlag Berlin GmbH. This book was released on 2016-11-11 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of speech of people with Parkinson's disease is an interesting and highly relevant topic that has attracted the research community during several years. The advances in digital signal processing and pattern recognition have motivated the research community to work on the development of computational tools to perform automatic analysis of speech. Most of the contributions on this topic are focused on sustained phonation of vowels and only consider recordings of one language. This thesis addresses two problems considering recordings of sustained phonations of vowels and continuous speech signals: (1) the automatic classification of Parkinson's patients vs. healthy speakers, and (2) the prediction of the neurological state of the patients according to the motor section of the Unified Parkinson's Disease Rating Scale (UPDRS). Recordings of three languages are considered: Spanish, German, and Czech. German and Czech data were provided by other researchers, and Spanish data were recorded in Medellin, Colombia, during the development of this work. Besides the classical approaches to assess pathological speech, a new method to model articulation deficits of Parkinson's patients is proposed. This new articulation modeling approach shows to be more accurate and robust than others to discriminate between Parkinson's patients and healthy speakers in the three considered languages.
Download or read book Automatic Speech Signal Analysis for Clinical Diagnosis and Assessment of Speech Disorders written by Ladan Baghai-Ravary and published by Springer Science & Business Media. This book was released on 2012-08-09 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automatic Speech Signal Analysis for Clinical Diagnosis and Assessment of Speech Disorders provides a survey of methods designed to aid clinicians in the diagnosis and monitoring of speech disorders such as dysarthria and dyspraxia, with an emphasis on the signal processing techniques, statistical validity of the results presented in the literature, and the appropriateness of methods that do not require specialized equipment, rigorously controlled recording procedures or highly skilled personnel to interpret results. Such techniques offer the promise of a simple and cost-effective, yet objective, assessment of a range of medical conditions, which would be of great value to clinicians. The ideal scenario would begin with the collection of examples of the clients’ speech, either over the phone or using portable recording devices operated by non-specialist nursing staff. The recordings could then be analyzed initially to aid diagnosis of conditions, and subsequently to monitor the clients’ progress and response to treatment. The automation of this process would allow more frequent and regular assessments to be performed, as well as providing greater objectivity.
Download or read book Computational Paralinguistics written by Björn Schuller and published by John Wiley & Sons. This book was released on 2013-09-17 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the methods, tools and techniques that are currently being used to recognise (automatically) the affect, emotion, personality and everything else beyond linguistics (‘paralinguistics’) expressed by or embedded in human speech and language. It is the first book to provide such a systematic survey of paralinguistics in speech and language processing. The technology described has evolved mainly from automatic speech and speaker recognition and processing, but also takes into account recent developments within speech signal processing, machine intelligence and data mining. Moreover, the book offers a hands-on approach by integrating actual data sets, software, and open-source utilities which will make the book invaluable as a teaching tool and similarly useful for those professionals already in the field. Key features: Provides an integrated presentation of basic research (in phonetics/linguistics and humanities) with state-of-the-art engineering approaches for speech signal processing and machine intelligence. Explains the history and state of the art of all of the sub-fields which contribute to the topic of computational paralinguistics. C overs the signal processing and machine learning aspects of the actual computational modelling of emotion and personality and explains the detection process from corpus collection to feature extraction and from model testing to system integration. Details aspects of real-world system integration including distribution, weakly supervised learning and confidence measures. Outlines machine learning approaches including static, dynamic and context‐sensitive algorithms for classification and regression. Includes a tutorial on freely available toolkits, such as the open-source ‘openEAR’ toolkit for emotion and affect recognition co-developed by one of the authors, and a listing of standard databases and feature sets used in the field to allow for immediate experimentation enabling the reader to build an emotion detection model on an existing corpus.
