Please, check my proposal. :)
Practice Japanese with Sound! Check my DTube channel for more practice!
Just focus how it's heard and try to imitate the sound until your muscle remember, like we did to learn our mother tongue when we're baby.
Don't use your brain, but your muscle. For example, even though you understand how to ride one with your brain, you'll never be able to ride a bicycle without training yourself until your muscle remember how to move. Language is same, I guess.
In the real life situation, it's too slow to use that you find the way of speaking and bring it out from you brain. To make a sound with your mouth as soon as you think, your muscles around mouth must remember how to perform without a control from your brain.
if you want to read or write Japanese, you have to know the grammar, the meaning of words and the spellings, for sure. However, if you go to Japan and spend a few days there, you don't have to know the language as a whole to have a casual communication with Japanese people.
Need to say more complicate expression? Then, use a translation app on your phone. However, it's still fun to speak foreign language yourself, isn't it? If you think so, this will be one of the helpful sources for you to prepare the fun.
Just practice some expressions you might think useful with this method. I guess it'll be helpful as it was to me. Let's get it on!
