Listen again to the sentence you have just heard. Listen to the melody of the phrase: the voice tone raises at the last stressed syllable (u-) and then it lowers at the final syllable (-na).
Now listen to the sentence as many times as you want and pay attention to the graphic. Watch (and listen) that the voice tone raises at the last stressed syllable (u-) and then it flowers at the final syllable (-na).
