The study examines interactions associated with foreigner-directed speech (FDS) within EFL triadic conversation exam where learners differ in outspokenness. The results showed that learners' outspokenness affected foreign examiners' vowel articulation. More vowels underwent distinct change across learners' positive-coded utterances in F2, whereas in F1 the vowel change in the high-communicative group during the introduction of a new question was the greatest source of variation. The findings suggest that native speakers tend to hyperarticulate during interactions with the low-communicate group, and probably with didactic intent to instruct or smooth communicative situations, in particular during more encouraging speech acts.
