However, perhaps a better comparison would be to that of a song's notes (or a dial tone modem doing an impression of a violin and being DAMN GOOD at such) there are different and distinct pitches.
One can say the same word with different emphasis and have it mean an entirely different thing. That said, a Cybertronian's name in their modern language and in Source.the comparison is akin to a singe sentence versus an entire book of meaning. Source is capable of expressing a mind-blowing amount of information in a very short amount of sound.but whether or not all this information is understood remains to be seen.
