In French, questions / queries are not pronounced with the same intonation as answers / statements.
The voice rises at the end of a sentence to indicate a question:
Tu manges des oranges ?
If a sentence starts with an interrogative word, the voice rises at the beginning of the sentence:
Combien d'oranges ?
The voice drops at the end of the sentence to show that it is an answer or a statement:
Deux kilos d'oranges.
The voice rises for questions without interrogative words.
To ask a question, the voice rises at the end of the sentence. The voice rises from level 2 to level 4.

The voice rises for questions with interrogative words.
