Me either. No matter how hard I try, I just can't mimic the Dominican accent. This is very common. There are actually special courses(I don't think there are any in the DR but in the US to speak unaccented English) for non-native speakers to help them lose their accent.Accents are hard to lose. I left NY in 1980, but I still sound like one. My kids were born in southern NJ, I passed on some pronunciations and telltale words to them, especially my daughter. Coffee, water, chocolate. Dropped r’s. My son still puts out the garbage, which amuses his wife, because they only have trash down here.
Mr AE will never lose his accent, he’s been in USA 47 years. I will never sound like a Dominican.
