Experience I Had with a Reading Task.
Since my school days, I had a difficulty in pronouncing the words with its correct and proper sound. For example take the word 'coward', I always used to speak it as 'co-ward' rather than its actual pronunciation 'ka-ward.' This used to happen with a lot many words. Over the period of time, I stated reading out loud and started watching tutorials to improve my pronunciation.
This experience was significant in the sense that it thought me: when it comes to English language, there isn't just one way of pronouncing words, different person pronounce certain words in a different way as long as he/she learns the correct pronunciation. And that can only be done by reading out lound and paying attention to how our teachers pronounce words.
