Regarding speech understanding: I think even in everyday situations, we rarely understand other people 100% and derive the missing bits via context. I watched a lot of movies in the English original with English subtitles over the past years, and because of that, I am now used to be able to understand movie conversations 100%. Whenever I watch a movie in my native language (without subtitles), I sometimes have to pause and replay a scene to fully understand the dialogue. Sometimes it is virtually impossible, as the actor just mumbles a few syllables. When I ask other people watching with me what the actor just said exactly, they usually also don't have a clue, but it doesn't seem to bother them. Usually, the answer is something like "he certainly meant A, because B just did C, and now he is excepting D".
