In phonetic terms:
OIA

if ara a e e
au
Here we have only two types of changes : long vowels have become short and diphthongs have become monophthongs. In the phonemic statement we have to keep apart the changes of the vowel clusters from those of the simple vowels, while in the phonetic statement we can say that ai becomes ē and au becomes 7 and along with other long vowels like i ū and a they are shortened in a closed syllable. There is thus greater economy and a more accurate picture of facts.
