Hi everyone~ Maybe you have learnt Cantonese for sometime, but still got confused by some pronunciations, eg 你 nei5 Vs 李 lei5 講 gong2 vs 趕 gon2 ? Just found a website (in chinese though) which may help you: https://www.polyu.edu.hk/cbs/pronunciation/project/initiation there are exercises to help you differentiate the sounds :-D enjoy~
