Do people ask you to slow down or do they often ask you to repeat? If yes you need to slow down…. now!
As a non-native speaker it is likely that you pronounce some sounds incorrectly and use different stress and rhythms to native speakers. This gives you an accent and can make your English more challenging for people to understand. Slowing down helps as it gives your listeners time to process what you are saying. Don’t leave your listeners struggling to understand you. Instantly improve the clarity of your English by slowing down.
