I'm not entirely sure but she pretty much has sounded the same way in everything that I have seen her in. In a way, there would be no reason to have this particular affectation for the character in this show. However, it would be interesting and look at the various works she has done (she has been around a long time) and see if the affectation was the same. Believe it or not, I just saw The Big Sick and I thought she sounded pretty much the same way.
