?

? ? ? ? ? ? ??????(t) is not fully pronounced
?
* unreleased stop:
????When a plosive (/d/, /t/, /b/, /p/,?/ɡ/, /k/) comes before another consonant sound, the plosive is not fully pronounced as the release of the blocked air is not heard.
????當(dāng)一個(gè)破璧音(如/d/,/t/,/b/,/p/,/k/或/ɡ/)出現(xiàn)在另一個(gè)輔音音標(biāo)之前時(shí),在發(fā)音中一般這個(gè)破璧音不能被完整地發(fā)出,因?yàn)橐魳?biāo)后的聲音阻礙了其空氣的釋放。這種現(xiàn)象被稱為“未完全發(fā)音的破璧音”。這在英語(yǔ)口語(yǔ)中非常常見(jiàn)
?
***19. 加音 Intrusive /r/

* intrusion
????When a word ends in an /??/ sound and the next word begins with a vowel sound, an /r/ sound is sometimes added, even if there is no ‘r’ in the spelling.
????當(dāng)一個(gè)單詞以 /??/ 音結(jié)束,并且下一個(gè)單詞以元音音開(kāi)始時(shí),有時(shí)會(huì)添加一個(gè) /r/ 音,即使在單詞拼寫(xiě)中并沒(méi)有“r”
