> Meanwhile, I’ve seen e.g. Mexican and Chinese ESL speakers have very bad mutual intelligibility, because they make very different mistakes. That's true. Assume a monolingual learner. You can predict the kinds of mistakes they will make based on their native language (phonetical, phonological, semantic, etc.). As a person learns more languages, they will likely get better at decoding these things. Particularly cultural based assumptions used in languages.
