齿后音

The sound segments are grouped into consonants and vowels.there are several basic ways in which articulation can be accomplished:the articulators may close off the oral tract for an instant or a relatively long period;they may narrow the space considerably;or they may simply modify the shape of the tract by approaching each other.manners of articulation:stop,fricative,approximant,lateral.other consonantal articulations include TRILL,TAP or FLAP and AFFRICATE.consonants may be produced at practically any place between the lip and the vocal folds.eleven places of articulation are distinguished on the IPA chart.

音段可以分成辅音和元音两类。有这么几种发音的方法：发音器官暂时或相对长时间地关闭口腔通道；发音器官空间缩小；或者，发音器官互相贴近形成不同形状的通道。发音方法：塞音，擦音，通音，边音。其他的辅音发音方法包括颤音，触音或闪音，塞擦音。辅音几乎可以产生于唇和声带之间的任何部位，国际音标表区别了其中11个发音部位。发音部位：双唇音，唇齿音，齿音，齿龈音，后齿龈音，卷舌音，腭音，软腭音，小舌音，咽音，声门音。

Results According to articulation position, 68.44% of misarticulations of functional speech disordes occurred in dental consonants; while 57.78% in palatal consonants; 23.11% in alveolar consonants; 24% in velar consonants; 14.67% in lateral consonant and 17.33% in retroflex consonants. According to speech pathology, 37.33% of misarticulations was palatalized misarticulation; while 22.67% lateral misarticulation; 21.33% inter-dental misarticulation; 8% palatalized misarticulation with lateral misarticulation; 5.33% lateral misarticulation with interdental misarticulation; 1.33% nasopharyngeal misarticulation and 4% others.

结果 功能性异常语音的异常语音出现率按构音点分：舌尖前音(68.44%)、舌面音(57.78%)、舌尖后音(23.11%)、舌根音(24%)和舌尖中边音(14.67%)、舌尖中音(17.33%)，它们可单独出现，也可两种异常音并存；按语音病理学分类：腭化音占37.33%、侧化音占22.67%、齿间音占21.33%、腭化音+侧化音占8%、侧化音+齿间音占5.33%、鼻腔音占1.33%、其它占4%。
