We have attended several international conferences where experts and very accomplished academics give their presentations by reading out verbatim from their prepared notes.

Why do we say things that are not true?

Even the Queen of England sometimes delivered recorded speech not even prepared speech

It is very common for German chancellor to deliver prepared speech.

It is a standard practice for a leader to have prepared speech by speech writer.

The following are leaders with their speech writer according to Wikipedia:
