I notice that people used to speak not necessarily more clearly, or distinctly, but their voice had a certain 'choppiness' to it that you don't hear anymore... Unless the person doing the speaking is doing it purposefully to sound old-timey. (Think of the narrator in the movie UP by pixar)
Here is an example of the speech type I am talking about: President Eisenhower ~1964
Here, in a 1950s newsreel, the newsman is speaking this way
It doesn't seem to be limited to just the United States either:
Various Newsreels - 1950s Germany, England, USA 220857-04 https://www.youtube.com/watch?v=6wW9CvJxuh8
I know that it can be attributed to 'times change', but I would just like to know why public speakers, and news anchors, etc have started using 'normal' sounding speech. It is somewhat of a shame this type of speech is slowly going away. The last place I currently hear speech of this type is during baseball games.
