发音方法:

/m/为双唇音;/n/为舌尖齿龈音;为舌根软腭音2/10发鼻音/n/时舌尖紧贴上齿龈形成妨碍，软腭下垂，气流由鼻腔逸出，/n/也是浊辅音，发音时声带振动;音素体验noodlessnowdancewoman发音方法:

3/10鼻音/ŋ/发音部位与/k//g/相同，舌根抬起贴住软腭，但发/ŋ/时软腭须下垂，打开鼻腔通道，气流从鼻腔逸出，/ŋ/也是浊辅音，发音时声带振动。音素体验asongmorningEnglish发音方法:

manfirstlandedonthemoon.7/10语音知识小站:辅音鼻腔爆破假如爆破音/t/或/d/后面紧跟着是鼻辅音/m/或/n/时，这种辅音组合在语音学里就叫做鼻腔爆破，换而言之，即发爆破音/t//d/时受后面鼻辅音/m/与/n/影响，爆破部位有所改变，须由口腔爆破改为鼻腔爆破。说得通俗一些，也就是/t/或/d/在上述组合中发音时爆破声音受鼻发音影响必须改道从鼻子里出来，所以发/tn/或/dn/这么组合时鼻子里会有一个冲气感觉。发爆破音时鼻腔总是关闭，除阻时气流只能从口腔冲出。不过当爆破音后面紧跟鼻辅音/m/或/n/时，爆破音形成妨碍，发生不完全爆破，在词末，必须经过鼻腔爆破。按通常方法成阻，短暂持阻后，突然打开鼻腔通路，让气流从鼻腔冲出。爆破音与鼻辅音之间不要加多出/ə/音。8/10比如:/dn/:garden;burden;pardon;wooden;sadnews;Good
