The perceptual development of Dutch listeners learning to perceive the Finnish quantity contrast /t-t:/ was studied. It is shown that short laboratory training is (i) sufficient to change identification of relevant speech sounds, but (ii) insufficient to substantially change perceptual sensitivity along the phoneme continuum. Furthermore, L2 learners need much more relevant language experience, but can obtain native-like sensitivity to the /t-t:/ contrast.
