Dr Joanna Przedlacka

Postdoctoral Researcher in Phonetics



I am an experimental phonetician with an interest in sociophonetic variation. I am currently investigating temporal properties of nasal energy patterns in in standard Polish with contact accelerometry (adhesive microphones) and dynamic monitoring of oral and nasal airflow. Recent projects include: (1) the acoustics of inter-speaker variation in Received Pronunciation in the 1930s;  (2) I have been co-investigator on a project ‘Greek in Contact’, which looks at the impact of long-term language contact on the intonational patterns of Greek varieties, whose speakers lived and interacted with Turkish and Italian speaking populations http://www.phon.ox.ac.uk/greekincontact (3) using autocorrelation to measure glottalisation in natural speech, where visual acoustic or auditory criteria are lacking.



Teaching and other activities


I teach Prelims Paper IX (Phonetics and Phonology), FHS Paper B/XII (Phonetics) and selected topics for General Linguistics Paper A. Before coming to Oxford I lectured phonetics for clinical, fieldwork and ELT purposes (UCL and De Montfort University). I am a co-organiser of the biennial Phonetics Teaching and Learning Conference and associate director of the Summer Course in English Phonetics at UCL. I have also been co-examiner for the International Phonetic Association’s Certificate of Proficiency in the Phonetics of English.
