I doubt very much that you do.
People don't understand other people's thoughts. At best they have a mental map that roughly corresponds to the gist of what they're saying and which triggers a patterned response thought in their heads.
While what I said was very tongue-in-cheek, it's also true. Even couples who love each other spend a large part of their time essentially shrugging their shoulders and thinking "Whatever" while going along with the situation or demands in order to avoid an unnecessary fight or argument.
People are not logical in their communications. They're fragmented and riddled with assumptions about culture, phrasing, and slang. Even when they speak a "common" language, such as English, people from different countries often have difficulty with casual communications because the details of the language as spoken in their homelands is so different.
Getting a voice recognition system to deal with accents is far from trivial, but even that is trivial compared to getting a system to grasp concepts from around the world.
Admit it: sometimes you don't even understand yourself, and wonder what triggered that random/perverse thought that just flashed by.
