When thinking about this I think about children, the reason for this is because when you are speaking to a child you may have to change the way you speak to them. When speaking to a child your vocabulary is very limited, only because the child most likely won't understand certain words that others use, meaning an older group or setting of people. I have come accrossed this many times, for example : When I'm babysitting, the ages may vary around 3-10. Depending on the child, you would have to speak in a way that they understand, like using small words and explaining it in the easiest way possible.
Another situation that i've had to speak a certain way was when speaking to someone who only spoke spanish. He could understand english when spoken to by others, but he could not speak the language himself. I had to speak slowly, only so he could have a better understanding as to what I was saying and read my lips.
There are also people who use their hands to talk in general.
This is from my personal experience, but im sure that you get an idea of what it is the question means or is asking.
You can use this answer yourself, as i am sure you will get a 100 only because i did.
