In technical linguistic terms, this is the difference between phonology and orthography. Phonemes are the "smallest" identifiable units of sound in a language. Orthography refers to the set of symbols used to represent those sounds. So, letters are not sounds. Consider the different pronunciation of "x" in English: example compared to xylophone.

My example also illustrates that the rules by which the symbols get put together change the pronunciation, ie the sounds you produce in speaking. This is the linguistic property that describes the "invisible s" in your examples above.

Hope this helps, or at least satisfies. I honestly don't mean to lecture, but I'm an anthropologist and college professor, and would not have been able to get to sleep tonight if I didn't get this out of my head!
