I would like to ask about [how to say it]

[hhtt21]

Would you please explain how to ask someone questions in English?

How is this with respect to good use of words and naturality?

I would like to ask about some expressions which could be used in everyday ​speechs?

"Speechs" is not a word. You need the uncountable "speech". Other than that, the words are OK but the question mark is wrong. A sentence which starts "I would like to ask" is not a question; it's a statement so it should end with a full stop.

I'd use "naturalness" rather than "naturality". I had to look up 'naturality' to be sure it was even right, and it has a red line under it here.
