Listen again to the sentence you have just heard. Listen to the melody of the sentence: the voice falls at the last stressed syllable of the sequence (-ni-) and then rises and falls again at the final syllable (-u).
Now listen to the sentence as many times as you want and pay attention to the graphic. Watch (and listen) how the voice falls at the last stressed syllable of the sequence (-ni-) and then rises and falls again at the final syllable (-u).
