Ultrasound studies of lingual coarticulation

Dr. Aude Noiray

Two recent experimental studies have been published by Dr. Aude Noiray (Haskins affiliated scientist) and her group at Laboratory for Oral language Acquisition, University of Potsdam, (LOLA).

One reports on a cross-sectional investigation of 65 German children from 3 to 7 years of age using the technique of ultrasound imaging to examine the units of lingual coarticulatory organisation in early childhood.

The second study investigates coarticulatory resistance in German adults using Mutual Information.

Dr.  Noiray has also been invited by Pr. Martijn Wieling (Groningen University, Haskins affiliated scientist) to investigate the effect of alcohol on speaking and perceiving a second language at Lowlands Sciences 2018. 

For three days, together with a team of 10 students, Pr Wieling and Dr.  Noiray recorded 150 participants using ultrasound imaging and tested L1/L2 perception in 300 participants. A short video summary of the study and interview of Pr. Wieling is available here (with English. Subtitles) :https://www.youtube.com/watch?v=Qz0CsZw4Ck8#
