(6:05) Here, the reverend is saying "I feel like I'm experiencing something that's really nice with Nutella in it." But for me it actually sounds like "Nutellar in it."

(6:33) again, the woman is saying "but Netella is great", but it sounds like "but Nutellar is great."

And I couldn't find the clip, but in the TV show "Anne with an E", Marilla says "and be good friends with Diana again", but it actually sounds like "be good friends with Dianar again."

I often hear these [r] or [ar] sounds when natives speak English. What is this? Is this just their habits or Do they often do this to pronounce easier or something?
