1、国际音标是语音。而语言通常分为两大类：元音和辅音。国际音标共有48个，其中元音20个，辅音28个。分类的原则：根据其气流从肺部呼出时是否受发音器官的阻碍而定。发音时，气流不受任何发音器官阻碍的音位称作元音。气流受到发音器官任何一个部位阻碍时的音位称作辅音。国际音标的分类 长元音/i:/:/u:/:/:/单元音 元音 短元音/e/音标 双元音 /ei/ai/u/au/u/i/i/清辅音 /p/t/k/f/s/t/ts/tr/h/辅音 浊辅音 /b/d/g/v/z/d/dz/dr/m/n/l/j/r/w/元音的分类 单元音：12个元音 双元音：8个 发单元音时，颌、舌、唇不动，只是长元音发得长一些
2、，短元音发音时很短促。而在发双元音，是由一个元音滑向另一个元音产生的音。因此，颌，舌、唇有变动，但整个像一个长的单元音。单元音1.舌头轻抵下齿龈，舌前部抬高，但不接触上齿龈；2.嘴角向后缩，使双唇呈扁平状；3.气流从口腔中流出，振动声带，发出/i:/音。1.舌头轻抵下齿龈，舌前部抬高，但不接触上齿龈；2.嘴角向后缩，使双唇呈扁平状；3.气流从口腔中流出，振动声带，发出/i:/音。/i:/greentreeseameweseeshecleanseameettreemeal he she me we be teach meat meal sea please clean tree green se
