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 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 264 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.

Download or read book Analysis of Pathological Speech Signals written by Tomás Arias-Vergara and published by Logos Verlag Berlin GmbH. This book was released on 2022-12-15 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the automatic analysis of speech disorders resulting from a clinical condition (Parkinson's disease and hearing loss) or the natural aging process. For Parkinson's disease, the progression of speech symptoms is evaluated by considering speech recordings captured in the short-term (4 months) and long-term (5 years). Machine learning methods are used to perform three tasks: (1) automatic classification of patients vs. healthy speakers. (2) regression analysis to predict the dysarthria level and neurological state. (3) speaker embeddings to analyze the progression of the speech symptoms over time. For hearing loss, automatic acoustic analysis is performed to evaluate whether the duration and onset of deafness (before or after speech acquisition) influence the speech production of cochlear implant users. Additionally, articulation, prosody, and phonemic analyses show that cochlear implant users present altered speech production even after hearing rehabilitation.

Book Synopsis Automatic Evaluation of Tracheoesophageal Substitute Voices by : Tino Haderlein
Download or read book Automatic Evaluation of Tracheoesophageal Substitute Voices written by Tino Haderlein and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 20 to 40 percent of all cases of laryngeal cancer, total laryngectomy has to be performed, i.e. the removal of the entire larynx. For the patient, this means the loss of the natural voice and thus the loss of the main means of communication. A popular method of voice restoration involves a shunt valve (voice prosthesis) between trachea and pharyngoesophageal segment which establishes the tracheoesophageal (TE) substitute voice. From time to time, the substitute voice has to be evaluated by the therapist for the purpose of reporting therapy progress. This evaluation is subjective; it is therefore dependent on the particular expert's experience and similar factors. In the frame of this thesis, it was examined how automatic methods can be used in order to provide an objective means of the evaluation of substitute voices. There are some established objective measures which are, however, restricted to the evaluation of sustained vowels. In this thesis, the step from the automatic analysis of vowel recordings to text recordings is done. For judging speech quality objectively in a real communication situation, the analysis of entire words and sentences is necessary because the intelligibility of a substitute voice in a dialogue is a substantial criterion for evaluation. Automatic word recognition methods were applied to a standard text that was read out by the test persons. Information on the intelligibility of the individual speakers was gained by the comparison of word recognition rates with reference evaluation data from human experts. The use of a prosody module allowed to extract not only acoustic information on the speaker's voice, but it also measured individual speaking characteristics. The inter-rater variability among humans was compared to the automatic analysis results, and the main finding was that the correlation between human and automatic ratings was as good as the agreement among the human rater group. The automatic recognition could be slightly improved on distant-talking recordings by the use of mu-law features which are modified Mel-Frequency Cepstrum Coefficients (MFCC). Artificially reverberated training data for the recognizer is another possibility to achieve better recognition rates even when the reverberation in the test data does not match the acoustic properties of the training data. This is a step towards a therapy session where the patients will not be required to wear a headset any more.
Book Synopsis Analysis of Speech of People with Parkinson's Disease by : Juan Rafael Orozco-Arroyave

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 Human Activity Analysis in Visual Surveillance and Healthcare written by Muhammad Hassan Khan and published by Logos Verlag Berlin GmbH. This book was released on 2018-11-30 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automatic recognition of human activities enables their use in several interesting applications of daily life. This dissertation emphases on the analysis of human activities in a visual surveillance scenario and the classification of physical activities in the therapeutic procedure using visual data. The first part of the dissertation proposes a robust gait representation to recognise the identity of a person using his/her walking style, dealing with its several real world challenges as well as taking into consideration the effects of cross-view recognition. In the second part, a complete framework is proposed to capture and analyse the movement of different body parts in human which is useful in the clinical assessment to detect any movement disorders and the assessment of the desired therapeutic program.

Download or read book Voice Quality written by John Laver and published by John Benjamins Publishing. This book was released on 1979-01-01 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characteristic voice quality of a speaker conveys to listeners a wealth of information about his physical, psychological and social attributes. For this reason, voice quality is of interest to a wide range of disciplines, including linguistics, phonetics and speech science, speech pathology, sociology, psychology, medicine, and communication engineering. Literature on voice quality is, consequently, scattered through a correspondingly wide range of publications. While this bibliography is unlikely to be exhaustive, it aims to be comprehensive. Exceptions to this are purely medical literature and literature on speech pathology; also, although a number of different languages are represented, works in English received the principal coverage.
