I don't know if it's that easy to tell phonetic errors from non-phonetic errors in many cases because a lot of times people don't understand how a word is supposed to be pronounced. For example I saw someone write "dotson" for the type of dog that is called "dachshund". <br> <br> The actual pronunciation is something like "docks hoond" or "docks hund". My best guess is that this poor speller heard someone say "docks hund" and misheard it as "Dot son".
