> I was referring mostly to the way one structures their thought and expresses it to someone else.1. it's still relevant in spoken language. Perhaps more so -- inflection, intonation, volume, and speed add a lot of subtlety to vocal communication that is even more difficult to pick up on than written communication. Pauses indicate punctuation. Tone can indicate something is less important. Volume and speed can be used in place of parentheses or even footnotes. Those are just the obvious things. There is so much information that is very difficult for non-native speakers to pick up on. Or at least is very difficult for me to pick up on.
2. They might be speaking in a way that parses well to a native ear but is deeply confusing to a non-native speaker.

Here's a really important question: do other native speakers in your group express the same frustration about these SWEs?
Communication is a two-way street.
If they are 3/5 on communicating ideas and you are 3/5 on understanding ideas, then you may have issues that a person who is 5/5 on understanding ideas does not have.
I want to stress that even if you were a 1/5 (you're not!!!), the onus would still on BOTH you and your team mates to communicate well. It's not just your job to get better at understanding their mediocre communication; it's also their job to be empathetic and learn how to communicate better with you.
Example: I communicate a bit differently with non-native speakers in spoken communication. I slow my speech just a bit (not excessively -- I talk very fast naturally, so my slow is others' normal). I avoid complex wandering sentences with clauses that resolve on different sides of the sentence. I try to add more roadmaps and use more explicit communication. I rely less on intonation, inflection, and pauses to convey meaning when speaking. I made these changes after I worked in a country with a different language and realized how damn hard it was to understand that last 20% of information that everyone else seemed to be catching.
