The [u?] diphthong. This is another diphthong that is sometimes left out of sources as it is always followed by the consonant R, and these sources consider the schwa sound, the second half of this diphthong, to not actually be its own sound.

The first sound: uh as in pull is how it is written. However in practice, I find it to have some of the oo as in boo mixed in. luh-uh-uh-uh as in lure. In slow motion: ooooo uuuuuuuhhhh rrrr. So the sound goes from the uh or oo sound, where the lips are more rounded, to the schwa, where the mouth is very relaxed and the tongue is very relaxed, to the rr, rr, where the lips come in a little bit, the then push out a little bit, and the throat closes a tiny bit here to make the sound come from uhh.

[u?]是一個雙元音，有些研究發音的材料中認為這個音是[u]和R音的組合，當中的[?]音并不發聲。

第一個音，雖然寫做[u](pull一詞中的[u]音)，但是念的時候卻混合了一些[?]的成分(boo一詞中的[?]音)。我們來試著念一下lure一詞中的[u?]音，用慢動作來念就是：ooooo uuuuuuuhhhh rrrr。也就是說，[u?]這個音是從唇形較圓[u]或者說[?]音，到嘴型和舌頭都十分放松的[?]音，再到嘴唇略微向中間聚攏并向前突出，而喉嚨處略微縮緊的R音。

Sample words:

sure 確信的

endure 忍受

secure 安全的

Sample sentence:

Its pure allure made me want to buy it. 那種純粹的誘惑力讓我非常想買下它。
