The positions I usually hire for are very specialised indeed, but I guess it's also comes down to cultural differences. In Norway you would usually specify at which level you know human and computer languages and it would be considered quite rude to put something on the CV that you only have a basic knowledge of. It gives off a feeling of "padding the CV" to appear better than it really is. If someone writes that they know a (human) language without further specification I'd expect them to be able to speak and write it in a professional setting.
