Item Automatic English phoneme recognition from articulatory data generated by EPG systems with grid and anatomical layout of contact sensors(Australasian Speech Science and Technology Association Inc., 2019-08-22) Krynicki, Grzegorz; Dziubalska-Kołaczyk, Katarzyna; Weckwerth, Jarosław; Michalski, Grzegorz; Kaźmierski, Kamil; Maciejewska, Barbara; Wiskirska-Woźnica, Bożena; Żygis, Marzena; Kuczko, Wiesław; Sekuła, AlicjaThe aim of the study was to conduct automatic phoneme identification from articulatory data that accompanied the production of these phonemes in continuous speech. The articulatory data were obtained from 2 electropalatographic systems, Palatometer by Complete Speech and Linguagraph by Rose-Medical. Palatometer was used with the artificial palate containing 124 contact sensors in a grid layout, including 2 sensors monitoring the lip contact. The palate included a vacuum-thermoformed flexible printed circuit. Linguagraph was used with the acrylic artificial palate designed and developed for the purpose of this study, containing 62 electrodes in anatomical layout. Palatometer was used by one native of General American and Linguagraph by one native of General British, each reading 140 phonetically balanced sentences that included Harvard Sentences and TIMIT prompts. The EPG data were parametrised into dimensionality reduction indexes, which were analysed by means of linear discriminant analysis and a probabilistic neural network. The results of classifications are discussed.Item Doing phonetic transcription on Moodle(2013-05-06) Aperliński, Grzegorz; Łodzikowski, Kacper; Weckwerth, JarosławMoodle is an open-source learning management system, one of the leading e-learning platforms in use today at all levels of education. It has been successfully used in the teaching of phonetics and pronunciation (e.g. Ashby et al. 2009; Wilson 2008). This paper will present various aspects of the use of phonetic transcription on Moodle on the example of a b-learning module supporting a course in English Phonetics and Phonology within a university programme in English Studies. First, we will present our approach to interactive transcription exercises based on two Moodle question types: multiple choice and short answer with input from a custom-developed keyboard with IPA symbols. Pre-programmed hints for both wrong and correct answers provide comprehensive just-in-time feedback, which creates a more personalised and effective learning environment. A survey on students’ attitudes to Moodle solutions shows, however, that students prefer paper exercises because they can be completed faster. Various ways of delivering phonetic transcription to participants for presentation purposes will be presented (image vs. PDF vs. Flash vs. Unicode text), and their relative strengths and weaknesses will be discussed. Methods of styling the Unicode text of phonetic transcription as part of Moodle web pages will be described. Finally, we will demonstrate how the preparation of quiz questions can be automated and performed in batch mode offline (bypassing the often cumbersome question-building interface of Moodle) using widely available word-processing software such as MS Word.
