Use quotation marks only when a speaker is quoting textually. Use double apostrophes as it.
[00:00:00] Article 14 says: "It is allowed to..."
[00:00:00] My uncle said: "It's really hot today", and I said: "Yes, it is".
Never use quotation marks to indicate indirect quotes, single words or in another language, titles of books or movies, proper names, and so on. You should only use quotation marks when the speaker textually quotes something that someone said or reads a text out loud.
