@Sudii, @Mirko Thank you

Provided that there are tons of ways to improve and master a foreign language, as far as I'm concerned , the best way to improve one's speaking skills is speaking with a native. If you don't have the chance to do that , I suggest you to watch tv series or movies in the language you wanna learn with subs on. It'll help you to acquire new vocabulary , idiomatic and colloquial expressions that you won't find on any kind of books. In addition , you can listen to podcasts online or you can download them and put on your mobile so that you can listen the audios no matter where you are and still practice. This is helping me a lot to improve my english skills. I also find useful to subscribe to native speakers' channels on youtube. This is all it comes to my mind at the moment , hope it helps!

I'm learning English and Chinese now. Sometimes I watch western movies and listen to English/Chinese music to know how to pronounce the words well. And it also help me to improve my listening skill. Besides, it also help me to know how to use the word that I learn in a sentence (especially in chinese).
