It doesn't bother me just quick question that came to mind. I was thinking that we don't have to right like we talk. Like I came across a post where too dwarfs were writing like they would talk in RP. Unless the character isn't good at spelling we should write without any "Ye" "Aye" and "oi." We might say "Yo wassup man" but we don't right like that on our school or work papers. Just some thing to think about.
Getting back to the original post, and feeding off of Script Wreck's arguments a little, I'd like to add that while we don't write like that on our school or work papers, we often write in various language forms informally as in text message.
Similarly, other language forms often find their way into the works of literature. Some examples would be slave dialect in many slave narratives and later African American literature, NADSAT from
A Clockwork Orange (which as a form of slang pulls a lot from both English and Russian), and Newspeak from
1984. And while I realize the Dwarven community does not rise to the literary genius of Douglass, Burgess, or Orwell, there is a common feature among them all--a sense of a separate community. The Dwarf-common language form marks a particular set of Dwarves. Part of living in this community and adopting this culture is adopting the particulars of its speech. In this way Dwarf-common has almost been given a life of its own from the common; it is no longer an accent. It no longer represents how any one player types, but how an entire community uses a language to form a specific culture.
In my particular Dwarf's RP, I do the accent to represent his inability to grasp common completely. I don't speak with the accent when I speak Dwarven. Part of this has to do with Nokka's stubbornness, and part is an OOC reason relating to insufficient intelligence to speak two languages fluently. I like when people RP not understanding Nokka's broken speech, too. It adds a nice element.
As far as accented writing goes like "Ye", "Aye", and "Oi". It could be that the Dwarves learned phonetically and not through word-recognition. Thus, when their teacher told them to "sound it out" there could be much room for error. Also, "Ye" and "Aye" just come from an older form of English, and are not necessarily transformations of language particularly for Dwarves.
