This study examines the perception of L1 speech of 14 late Czech-French bilinguals who have been living in France for at least two months by Czech monolinguals. We wanted to know whether native speakers judge the L1 production of late Czech-French bilinguals differently from the L1 production of Czech monolingual.
The perceptual experiment involved samples taken from L1 production of the bilinguals and Czech monolinguals in a reading task and a semi-spontaneous speech task and was submitted to 17 Czech students of phonetics in the Charles University in Prague. The results show a significant difference between the perception of L1 speech of bilinguals and monolinguals and between the two production tasks.
