In many medieval movies such as Braveheart there are often scenes with military commanders shouting motivational speeches to entire armies on the battlefield without using voice amplification of any sorts. In real life, were they really able to hold speeches like that and is this how it was done?

It just seems unrealistic that 10.000 people would be able to keep quiet enough and all at the same time for everyone to be able to hear one person shouting? Did they use some sort of equipment? Did they relay messages to officers down the line or did they just not speak to the masses like that at all?
