This document discusses a study that examined whether English speakers learning Spanish would eliminate aspiration of voiceless stops like "p", "t", and "k" after practicing pronunciation. Nine students participated, with five in the experimental group practicing a technique to reduce aspiration and four in the control group. Pre- and post-tests showed that the experimental group greatly improved in eliminating aspiration, while the control group showed almost no change. The results confirmed that focused practice can help English speakers improve pronunciation of these Spanish sounds.
