Participants
The interviewees in the Czech subcorpus are twenty-five secondary-school English teachers (19 female, 6 male; mean age=40.2 years) based in different regions of the Czech Republic. Their self-assessed proficiency was B2 (n=1), C1 (n=9), C1+ (n=5) and C2 (n=10).
The speakers in the parallel native-speaker corpus are fifteen English teachers (8 female, 7 male; mean age=32.6 years) from the US, UK, and South Africa, currently teaching in the Czech Republic. A range of metadata was collected through a speaker-profile form, in which the speakers’ informed consent to the use of the data for research purposes was signed.
