> I don't think I've heard any dialects where there's a difference between whether you pronounce the "c" in a word as hard or soft.
Um, yes, I can't think of regular words where a "c" changes.

Place names. Place names - at least in England - can have significant differences between spelling and pronunciation, and the locals will often use or be aware of a local pronunciation that isn't obvious to outsiders. Examples include Bicester ('bister'), Leicester ('lester'), Salisbury ('solsbry'), Tottenham ('totnam') and many others. It's not quite the same effect as with dialects but it certainly complicates spelling reform.
