It's easier to remember the image of a word than the sound, so you close your eyes and see the words, instead of hearing the sounds. For each word you can relate it to other stuff, so if a word is "dog" perhaps I could think of my friend's dog and his toxic farts. Or something 😅 so it has more meaning for me. Then say this things out loud can help but I guess make sure nobody is hearing, specially your wife, if you're lucky enough to have one!
