3rd French line: if you don’t hear the une in une dizaine d’années, don’t despair. This sound does not exist in English. Your ears will start to pick it up in the weeks and months ahead.
4th French line: notice that “quand on” sounds like “canton.” Of course “un canton” is a real word, but here, you don’t hear any article. A French listener will therefore not be confused: they hear the sound canton and think, “quand on.”
