Types of English pronunciation

Broad Australian (or Uneducated, Popular Australian) is a substandard norm distinguished from the others chiefly by its vowel nuclei, the nature of its diphthongs and a good deal of nasality.

In spite of the fact that the three varieties of Australian English are easily identified, one can hardly draw a firm border between them. The three types of Aus E pronunciation are characterized by a high degree of sameness. At the same time they are differentiated from RP not only in the system of sounds, but also in word-stress and intonation.

Owing to increasing urbanization in Australia (incidentally, Australia is one of the highly urbanized countries in the world, about 86% of the population live in cities and towns) differences in pronunciation tend to become less marked. It is fairly accurate to say that Australian English tends to become more and more homogeneous.
The following simple vowels (monophthongs and diphthongized vowels) exist in GAu;

/i/ as in the word seat /sIt/

/ı/ » sit /sIt/

/ɛ/ » head /hɛd/

/æ/ » had /hæd/

/ʌ/ » father /ˈ fʌðƏ/

/ɔ/ » hot /hɔt/
