Nasals,Approximants&Lateral/2021/3/29 星期一1Nasals,Approximants&Lateral(s)Like the stops,the nasals are all made by closing the vocal tract at some point in the mouth.Unlike the stops or any other sounds in the language,there is an opening into the nasal cavity in the pronunciation so that the sound can be resonated through the nose.The nasal consonants are/m/,/n/,and/./w/,/r/,and/j/are called approximants because it is an articulation in which the articulators approach each other but do not get sufficiently close to each other to produce a complete consonant such as a stop,nasal or fricative./l/is called a lateral because during its pronunciation,the passage of air through the mouth does not go in the usual way along the centre of the tongue.2021/3/29
