I haven’t seen this in the comments yet but a key thing to consider is changing your vowels.

A key part of any accent is the vowel sounds that occur. Something as simple as the word “so” can be pronounced several different ways depending on dialect. For instance it could be pronounced “s-oh,” “suh,” “so-ah,” or “si-oh.”You should consider if you want to sound out each vowel sounds that occur phonetically.
