The dataset contains two .csv files with the results of two sets of perceptual tests (vowel discrimination and vowel identification) performed by 38-44 listeners who were Catalan speakers learning English as a foreign language. The participants were divided into three experimental groups according to the phonetic training they underwent (identification training, discrimination training or no training and were tested at three or four different points in time: pretest, posttest, posttest2 (only the control group) and delayed test. The dataset presents the different variables examined in the experiment (the crucial ones being testing time and word type) as well as other characteristics of the perceptual stimuli used in the task and the score obtained for each trial. Every row corresponds to the result for a given trial by a given speaker.
