Research interests

Her research interests include the development of automatic tools for the study of pronunciation variation, the study of phonetic detail in spontaneous, conversational speech and the integration of phonetic and linguistic knowledge into ASR technology.

From 2000 onwards, Barbara Schuppler studied Physics and Spanish Philology at the Karl-Franzens University of Graz and at the Universidad Autonoma de Madrid. She pursued the experiments for her diploma thesis at the group ‘Magnetometry and Photonics’ (Department of Experimental Physics) and graduated in 2007. In that same year, she received a Marie Curie Grant for a PhD position at the Centre for Language and Speech Technology at the Radboud University Nijmegen (The Netherlands). In 2009 and 2010, Barbara Schuppler spent several months as visiting researcher at the Norwegian University of Science and Technology in Trondheim. Being part of the RTN Sound to Sense gave her the chance to receive and contribute to interdisciplinary training at and with fourteen project partners from eleven countries. After teaching Physics and Spanish at the Graz International Bilingual School, she received a FWF funded Hertha-Firnberg Grant entitled ‘Cross-layer pronunciation modeling for conversational speech’. Barbara Schuppler started to work on that project at the SPSC Laboratory in 2012. In 2013 and 2014 she spent several months as visiting researcher at the Laboratoire de Phonétique et Phonologie, Paris. Since October 2018, Barbara Schuppler is leading a follow up project funded by the Elise-Richter Programme entitled ‘Cross-layer prosodic models for conversational speech’.
