School - anyone know how I can get information on female african slave(children) information or?

this is some of my suggestion how can you adapt british accent
1.Watch movies that the actress is british or the movie is from places in UK like harry potter
2.Listen to the songs from british and be a keen listener to their accent
3.study their words or how they pronounce it look for study material for acquiring british accent
4.the best is to find someone that is good in british or a british that can be a good conversation because the more you practice it with it will come naturally to you too
