Effects of perceptual training on the identification and production of word-Initial voiceless stops by argentinean learners of English

Ubiratã Kickhöfel Alves, Pedro Luis Luchini


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.
