I heard the sentence Car on a un and I notice that a un liaise with each other, but I cannot really hear what it sounded like. All I heard was an falling a.
Listen to 7:13 here.
Does it sounds like he say "Gar on nan"? How would you pronounce a un in this case. In my ears, a and un sounds almost the same; a is more "stiffer" and peaky while un is more a falling. But still, I cannot clearly hear if he melting a and un together, or include a new letter between just to make it sound more softer and fluent.
Also listen to c’est un moyen after 7:15. Does he forgot to pronounce the t or does this audio have sound issues?
