My question is based on how we have speakers and microphones to project the voice of the speaker but I wonder how it was done in the past. If kings or rulers called in all of their governors, public figure heads or even talked to entire villages, how did they make sure everyone heard them and their message wasn't misunderstood?
There's definitely more room for a great answer on this one, but the speaking without amplification section of the AskHistorians FAQ has some good answers to this question:

[deleted] replying to Before the age of electronic voice amplification, how did large crowds hear the speaker (i.e. a monarch or the Pope)?
/u/turtleeatingalderman replying to Historians, how did public figures and orators address large crowds in the past without microphones and speakers?
