Listen again to the sentence you have just heard. Listen to the melody of the sentence: the voice tone falls sharply in the last stressed syllable of the sequence and stays low until the end of the sequence.
Now listen to the sentence as many times as you want and pay attention to the graphic. Watch (and listen) how the voice falls sharply in the last stressed syllable of the sequence (-ca-) and stays low until the final syllable of the sequence (-sa).
