One of the biggest differences between the British and the American accents is that Americans always pronounce the letter R. In England the words “load” and “lord” would sound very similar since the R tends to be silent before another consonant. It’s also silent at the end of a word in British English. If you first started studying English outside of the United States, chances are you are creating the British R. Take a look at this short video lesson that I just posted on YouTube yesterday. I think it will help you. I find that the majority of my students are not pronouncing this sound correctly when they first come to see me for accent reduction lessons.
