I would recommend you to make some friends who speak native language that you're targeting.
In my case, when I was learning English, I was able to read and write well enough, but speaking was always my problem to solve.
I decided to make some American friends who I could speak English with.
Guess what! my English skill got rapidly improved, and my friends were even surprised and impressed with it.
In this case, again, I would recommend you to speak your targeting language to people to have some practices :)
