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
