Question

what is direct into indirect speech ​

Answer 1

Direct speech repeats, or quotes, the exact words spoken. When we use direct speech in writing, we place the words spoken between quotation marks (" ") and there is no change in these words. We may be reporting something that's being said NOW (for example a telephone conversation), or telling someone later about a previous conversation.

Reported or indirect speech is usually used to talk about the past, so we normally change the tense of the words spoken. We use reporting verbs like 'say', 'tell', 'ask', and we may use the word 'that' to introduce the reported words. Inverted commas are not used

Answer 2

it means that we convert a statement said in the first person into a statement said in the second person!
