The pedagogical effectiveness of ASR-based computer assisted pronunciation training

44830.pdf (Publisher’s version ) (Open Access)Computer Assisted Pronunciation Training (CAPT) systems with Automatic Speech Recognition (ASR) technology have become increasingly popular to train pronunciation in the second language (L2). The advantage of these systems is the provision of a self-paced, stress-free type of training with automatic feedback on pronunciation quality. Despite this popularity, little is known on the actual pedagogical effectiveness of these systems. In other words, little empirical evidence is available as to whether and to what extent the use of these systems can improve pronunciation quality for a learner, while it is well-known that ASR-based feedback on non-native pronunciation quality is not yet 100% error-free. The research reported on in this thesis investigates the pedagogical effectiveness of ASR-based feedback on segmental quality. The thesis starts by identifying pedagogical requirements for pronunciation training in L2. Existing CAPT systems are then critically examined to establish which pedagogical requirements can be achieved with current ASR-based CAPT technology. Some of these suggestions are subsequently implemented to develop a customized ASR-based CAPT system (Dutch-CAPT) for teaching Dutch pronunciation to adult immigrants. First, a method is presented to select important segmental errors made by learners of Dutch with different mother tongues. By means of auditory analyses of different speech databases, an inventory of eight Dutch phonemes that appear to be particularly problematic tp learn is obtained. This inventory is subsequently implemented in Dutch-CAPT, which offers a simple form of feedback on segmental errors. The improvement made by a group of immigrants who used Dutch-CAPT is measured and compared to that of controls. The results indicate that the ASR-based feedback provided yielded the largest improvements in the pronunciation of the targeted phonemes, despite occasional errors in the feedback. The thesis ends with suggestions to design pedagogically sound and technologically reliable ASR-based CAPT, and to evaluate these systemsRadboud Universiteit Nijmegen, 08 juni 2007Promotor : Boves, L.W.J.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
