One such system is used in the books of Franklin E. Huffman and others; a more recent scheme is that used in J.M. Filippi's 2004 textbook Everyday Khmer or Khmer au quotidien''. These systems differ in certain respects: for example, Huffman's uses doubling of vowel symbols to indicate long vowels, whereas Filippi's uses the IPA triangular colon vowel length symbol.
