The acquisition of voicing assimilation by advanced Hungarian learners of Spanish

This study examines the effect of explicit phonological instruction on the acquisition of variable /s/ voicing in Spanish by advanced Hungarian learners. Hungarian and Spanish have very similar yet not identical voicing assimilation (VA) systems; the most important difference lies in the pre-sonorant context as sonorant consonants trigger voicing assimilation in Spanish but not in Hungarian. Data were collected in acoustic experiments from 7 native speakers of Northern Peninsular Spanish and 12 Hungarian university students, advanced learners of Spanish. The latter group was tested twice: before and after a three-month Spanish phonetics and phonology course. Our data reveals that this amount of instruction is not enough for L2 speakers to overcome their L1 VA system, which might be attributed in part to the variable, allophonic nature of the process, the similarity between the two languages’ VA systems and lack of exposure to the relevant dialect

The Invariant in Phonology. The role of salience and predictability

This aim of this thesis is to give a phonological account of acoustic variation and reduction. It is argued that phonological representations are uneven and include information about the relative strength of the segmental and subsegmental units composing them. This unevenness implies a distinction between the invariant – the “phonetic essence” of a word, which is practically undeletable – and other units which can be dispensed with under certain circumstances. In the first chapter I compare different theoretical approaches to the problem of acoustic variation, in particular with reference to generative phonology and exemplar-based theories. In the second chapter I propose a model which combines aspects of Optimality Theory, Element Theory and usage-based linguistics. Additionally, I discuss the role of acoustic salience in the formation of the invariant. In chapter three, typological and experimental data are examined in order to establish a salience scale for consonants. In chapter four, the results of the acoustic analysis of four dialogues extracted from a corpus of spoken Italian are presented. As expected, highly salient consonants are preserved to a greater extent than less salient ones. In chapter five I attempt to identify the phonological correlates of acoustic salience and discuss other factors which may favor reduction and deletion, among which predictability. In chapter six I draw some conclusions, deal with some pending issues and suggest future directions for research

The Role of Emotional and Facial Expression in Synthesised Sign Language Avatars

This thesis explores the role that underlying emotional facial expressions might have in regards to understandability in sign language avatars. Focusing specifically on Irish Sign Language (ISL), we examine the Deaf community’s requirement for a visual-gestural language as well as some linguistic attributes of ISL which we consider fundamental to this research. Unlike spoken language, visual-gestural languages such as ISL have no standard written representation. Given this, we compare current methods of written representation for signed languages as we consider: which, if any, is the most suitable transcription method for the medical receptionist dialogue corpus. A growing body of work is emerging from the field of sign language avatar synthesis. These works are now at a point where they can benefit greatly from introducing methods currently used in the field of humanoid animation and, more specifically, the application of morphs to represent facial expression. The hypothesis underpinning this research is: augmenting an existing avatar (eSIGN) with various combinations of the 7 widely accepted universal emotions identified by Ekman (1999) to deliver underlying facial expressions, will make that avatar more human-like. This research accepts as true that this is a factor in improving usability and understandability for ISL users. Using human evaluation methods (Huenerfauth, et al., 2008) the research compares an augmented set of avatar utterances against a baseline set with regards to 2 key areas: comprehension and naturalness of facial configuration. We outline our approach to the evaluation including our choice of ISL participants, interview environment, and evaluation methodology. Remarkably, the results of this manual evaluation show that there was very little difference between the comprehension scores of the baseline avatars and those augmented withEFEs. However, after comparing the comprehension results for the synthetic human avatar “Anna” against the caricature type avatar “Luna”, the synthetic human avatar Anna was the clear winner. The qualitative feedback allowed us an insight into why comprehension scores were not higher in each avatar and we feel that this feedback will be invaluable to the research community in the future development of sign language avatars. Other questions asked in the evaluation focused on sign language avatar technology in a more general manner. Significantly, participant feedback in regard to these questions indicates a rise in the level of literacy amongst Deaf adults as a result of mobile technology

CLARIN

The book provides a comprehensive overview of the Common Language Resources and Technology Infrastructure – CLARIN – for the humanities. It covers a broad range of CLARIN language resources and services, its underlying technological infrastructure, the achievements of national consortia, and challenges that CLARIN will tackle in the future. The book is published 10 years after establishing CLARIN as an Europ. Research Infrastructure Consortium
