Abstract
In this study, we investigate the effectiveness of perceptual training, administered to Argentinean learners, in the perception and production of word-initial voiceless stops in English. 24 participants were divided into 3 groups: (i) Group 1, which participated in 3 training sessions; (ii) Group 2, which, besides performing the same training tasks, was explicitly informed about the target item; (iii) Group 3 (control). All participants took part in a pre-test, a post-test and a delayed post-test. In all these phases, they participated in a consonant identification task and took part in a reading exercise. Our results show a significant increase of both experimental groups in identification. As for production, Group 2 exhibited a significant increase in /p/ and /t/ after training. These results are indicative of the effectiveness of perceptual training tasks in helping learners focus on Voice Onset Time.

Summary
Many studies focusing on the role of L2 pronunciation teaching have been proposed in the last few years. In order to evaluate the role of these practices, factors such as the irst language, the target language, the learners’ proiciency level and the phonetic aspect under investigation, among many others, should be considered. Bearing this in mind, in this study we investigate the role of perceptual training in the acquisition of aspirated initial stops by Argentinean learners of English. English has a two-way voice distinction for stops in word-initial position. His distinction is clear as, in word-initial position in English, voiced plosives are generally produced with Voice Onset Time (VOT) is the main acoustic cue employed by speakers of English when distinguishing /p, t, k/ from /b, d, /. his distinction is clear as, in word-initial position in English, voiced plosives are generally produced with
