Is there a term for speaking English with a foreign accent to make it easier for foreigners to understand?
An affected accent comes to mind which does not cover the reason behind the accent
I stumbled upon an article today and was reminded of the term I was looking for.
"speech accommodation"
And some interesting reading on the matter.
Accommodation most often takes the form of convergence, when a speaker chooses a language variety that seems to fit the style of the other speaker.
