Sort of, sort of not. It depends on the language. English for example is mostly a "stress-timed" language, which means the time between each stressed syllable is more or less perceived to be constant. Since there is usually 1 stress per morpheme, you can recognize when you are now in a new morpheme, though not at the "boundary". Morpheme is not quite the same as word, though.
