Direct and indirect speech:

When the words are delivered exactly as the speaker spoke them, it is referred to as direct speech. In other words, things are quoted as exactly they are.

Reported speech is another name for indirect speech. It's sometimes referred to as indirect narration or indirect speech. Indirect speech is when we report what someone else said with our own words but keep the meaning of what they said the same.
