I’ve been reading the SD long enough to know that there is no official accent for English. We are all the same here! gives all the English Speakers in the world a big hug
But I do have a question. Is there a term for measuring global understandability?
For example, I have talked to a guy that recently came to the US from Africa (I think Liberia). He told me English was his first language, but to my American ears he was extremely difficult to understand. His accent was very strong, and he constantly used words I had never heard of (types of slang I assume). However, he did not have much of a problem understanding me.
I presume this is because he has probably watched many American movies/television shows and is therefore is more able to understand my “version” of English.
Is there a term for this? If I were to speak into a microphone and it was played for all of the native English speakers, I would guess that maybe 70-90% of them world would be able to write down almost exactly what I said. I am guessing if this guy did the same, it would be much lower, maybe 20-30%, if that high. I would say my global understandability is higher than his. Is there a linguistic term for this?
