manfirstlandedonthemoon.7/10語音知識(shí)小站:輔音鼻腔爆破假如爆破音/t/或/d/后面緊跟著是鼻輔音/m/或/n/時(shí)，這種輔音組合在語音學(xué)里就叫做鼻腔爆破，換而言之，即發(fā)爆破音/t//d/時(shí)受后面鼻輔音/m/與/n/影響，爆破部位有所改變，須由口腔爆破改為鼻腔爆破。說得通俗一些，也就是/t/或/d/在上述組合中發(fā)音時(shí)爆破聲音受鼻發(fā)音影響必須改道從鼻子里出來，所以發(fā)/tn/或/dn/這么組合時(shí)鼻子里會(huì)有一個(gè)沖氣感覺。發(fā)爆破音時(shí)鼻腔總是關(guān)閉，除阻時(shí)氣流只能從口腔沖出。不過當(dāng)爆破音后面緊跟鼻輔音/m/或/n/時(shí)，爆破音形成妨礙，發(fā)生不完全爆破，在詞末，必須經(jīng)過鼻腔爆破。按通常方法成阻，短暫持阻后，突然打開鼻腔通路，讓氣流從鼻腔沖出。爆破音與鼻輔音之間不要加多出/?/音。8/10比如:/dn/:garden;burden;pardon;wooden;sadnews;Good
