Hello! I hope you don't mind if I correct you a bit!
To say "Speak" and "Converse" in the same sentence isn't helpful, they're synonyms! That means that they have an almost identical meaning.
Be careful of run on sentences! If you use periods between thoughts, that tends to help your writing look more natural. An example of this would be, "My name is Esmelin. I want to learn English. It would be nice to watch movies without subtitles."
I'm not the best at explaining these things, but if you have a teacher I'm sure they could elaborate on when to stop a sentence!
You also don't need to say 'official idiom', it doesn't make sense in this situation.
Here's a more grammatically correct and natural way to say the same sentence.
I want to learn English. Why? I'd like to speak with others and also watch the movies and TV shows I like without subtitles!
