Harshness is absolutely a metadata of language, at least as important as the dry content. If I say "pass me the salt", but do so with a loud and angry voice, far more is being communicated than the simple request to pass a salt. Phrasiology is part of communicating harshness. Failure to read language metadata is a judgment problem. With good employees, no matter the background, it almost never takes more than a few weeks to accurately interpret metadata. If they don't and they constantly fall back to "well, actually, a robot might not have understood it" and constantly expect disambiguation, this is an insurmountable issue.
