2.4.4. 元音 + 元音（Vowel + Vowel）

“元音 + 元音” 的组合之中，会出现加音（intrusion）。

In combinations of "vowel + vowel", an intrusion sound may occur.

前一个元音以 ɪ/i/iː 结尾，会出现加音 j：

When the first vowel ends in ɪ/i/iː, an intrusive j sound emerges:

I am - ˈaɪ ˈæm ⭢ ˈaɪjæm

He is - ˈhiː ˈɪz ⭢ ˈhiːjɪz

She is - ˈʃiː ˈɪz ⭢ ˈʃiːjɪz

They are - ˈðeɪ ˈɑːr ⭢ ˈðeɪjɑːr

前一个音节以 ʊ 结尾，比如 ʊ/uː/aʊ/oʊ，会出现加音 w：

Similarly, when the preceding syllable ends in ʊ, such as ʊ/uː/aʊ/oʊ, an intrusive w sound appears:

Go away - ˈɡoʊ əˈweɪ ⭢ ˈɡoʊwəˈweɪ

Do all - ˈduː ˈɔːl ⭢ ˈduːwɔːl

Do it - ˈduː ˈɪt ⭢ ˈduːwɪt

Throw it - ˈθroʊ ˈɪt ⭢ ˈθroʊwɪt
