ELI5: Why do newscasters always speak with the same specific inflections?

I’ve noticed no matter where the newscast is from, all news reporters speak in the same cadence that you would never use in real life. Why do they do this?

They’re trained to. Not all journalism schools have a formal voice class as a requirement for graduation, but many do, and even if they don't a certain amount of coaching about speech and delivery is a part of the curriculum.

This is done this because having a clear, consistent delivery makes the news easier to listen to and digest for a viewer. Most news anchors speak slightly slower than a normal cadence, fully annunciate every word, change tone throughout the sentence and have a fairly neutral, flat accent. That leads to a consistent "broadcaster voice." Contrast that to, say, an anchor who speaks in a fast monotone, runs words into each other, and has a thick Boston accent. Who would you rather listen to reading the news?
