As far as the nucleus is concerned, SA does not allow more than two slots linked to a
monophthong or diphthong.
ii)
Monophthong (veni, cinco) and diphthong (autro).
The test results showed that the success rate of voice input was over 98%, and the accuracy rate of spoken voices of
monophthong words, diphthong words and polysyllabic words was 97.15%, 94.96% and 93.62% respectively, suggesting that the system could accurately input and score English learners ' spoken English, and assist English pronunciation.
If, however, NEAR is followed by a vowel, it seems to be realized as a
monophthong plus /r/.
The formation of diphthong is the process of creating a diphthong of the original
monophthong. In Ibanik language, the construction of diphthong with VG pattern is a vowel followed by
monophthong.
In most dialects of English the vowel in bait is a diphthong, that is, it glides from one vowel /e/, to another, /i/, transcribed as [eI]; however, in Western Canadian English, the vowel in bait is often a
monophthong, phonetically transcribed as [e] (Hagiwara, 2005; K.
in 'gate', /e CAPITAL I/ is pronounced as a
monophthong, /e:/.
Use of the OO for /U/ is grouped with other spellings for
monophthong vowels that are not categorized as either "short" or "long," and Kirby spelled these with 83% accuracy.
This process involves the loss of the second part of a diphthong in order to create a
monophthong. As mentioned earlier in this study, this process can plausibly be accounted for by the fact that there are no diphthongs in Shona.
"This ei only later, probably in the second half of the 14th cent., was simplified to i, so that now high, nigh, sligh arose." According to Jordan's (1974: 132) quasi-sociolinguistic hypothesis, the monophthongised forms "first arose in vulgar language, while ouh, eih were the conservative more aristocratic pronunciations." Simultaneously, forms like heegh 'high' found north of the Humber seem to show that the
monophthong [e:] remained unchanged in that region (Brunner 1963: 23).
Interdialect forms arising from the simplification of the vowel system are infinitives like /h[??]:r/ 'to hear,' which are characterized by a standard
monophthong and dialectal loss of the infinitive ending.
There was one instance of monopthongization (the diphthong /aI/ is pronounced as a
monophthong) in the pronunciation of the word "desire".
