I work as an early-stage Marie Skłodowska-Curie researcher at Centre for Language Studies, Radboud University, under the supervision of Dr Esther Janse and Prof Mirjam Ernestus. As part of the ERICH ETN, my research project investigates the potential interactions between speakers' cognitive abilities and speech motor skills, and how these influence speakers' abilities to modify their speech when speaking (clearly) in noise. Speakers' individual differences in speech modification strategies, and how intelligible those speech samples are judged by listeners and algorithms (in collaboration with Prof Martin Cooke from University of the Basque Country) are also being evaluated.


So far, the cognitive and articulatory control aspects of my research are nearing completion. A conference paper on articulatory control in speech production was presented at the International Congress of Phonetic Sciences (Melbourne, 2019). A journal paper on the relationship between articulatory and cognitive control has been submitted to the Journal of Speech, Language and Hearing Research, and it is currently revision. Additionally, machine-predicted intelligibility gains from 78 speakers and listeners’ subjective judgements of a subset of the speakers are obtained, acoustic analyses of their speech data are also completed, writing up of the study is in progress. Lastly, a study exploring the differences in speech production mechanisms of two age groups (younger and older adults) have been carried out, and data analyses nearing completion.


Prior to my current post, I obtained an MSc degree in Forensic Speech Science at University of York, UK. During the master programme I have gained much knowledge in forensic phonetics, acoustics, and voice comparison. For my master's dissertation, I carried out a study on accent categorisation. After my master's degree, I kept on doing research work focusing on accents and dialects from both segmental and suprasegmental perspectives in non-standard as well as learner varieties of English.


Having studied the patterns and variations of (world) Englishes, I have developed interests in learning the underlying mechanisms (e.g. cognitive and motoric control) that contribute to individual variations in speech production. My current research project at Radboud University is, therefore, a perfect chance for me to explore.
