Another problem with oral history is translation. Whether the original language is Taiwanese, Hakka, or an aboriginal tongue, it is hard to say whether the original statements have been accurately rendered into modern Mandarin, or whether "something has been lost in the translation."
口述歷史還有語言轉換的問題，不管是閩南語、客語，或是山地語，轉換成如今通行的國語，這些轉換是否貼切，或者會相當程度的「失真」？
