communication techniques

How can I improve my speech ability & communication techniques (eg.fluency in language ) at home?
Can you suggest some methods or some websites I can go to?
Thank you in advance.
Actually, the simple act of reading can help.
Read, and pay attention to the language, the words, the sentence construction, the organization of a passage.
Over time, the quality of language you seek to emulate will become familiar and therefore easier to put into use.
It’s worth a try.
