Label a diagram by filling in missing words using exact words from the recording.
In the IELTS Listening Diagram Labelling task (without choices), you will see a diagram with some missing labels—this could be a map, a plan, or a drawing of a place, object, or process.
Your job is to listen carefully to the recording and fill in the blanks using the exact words you hear. There are no answer options given, so you must choose the correct words directly from the audio.
A visual example of sample question —
