高后圆唇元音在共时性上倾向于前化，在历时性上，高后圆唇元音比高前圆唇元音更倾向于前化。为了阐明这种前后不对称的原因，紧张和宽松的元音在三个地方的发音上下文中产生的七个第一语言的德国人在两个语音速率进行了分析生理，声学和感知。关节造影分析显示，在CV转换中，/u：，o：/的水平舌背运动的幅度和峰值速度大于/e：，i：/。第二个实验表明，紧张和松弛元音之间的差异，在舌背的水平位置是更大的后元音比前元音。第三个实验表明，/u：U/ of更有可能侵犯/y：，Y/空间，而不是其他方式的测量基于水平舌背位置和光谱斜率;一个类似的模式出现在一个被迫选择知觉实验的结果。一般的结论是，高后元音，如在德国的外围有很高的发音成本，这可以解释两个历时的趋势，后元音的前面，为什么没有一个高后元音往往有助于在世界上的语言不对称的元音分布。(C)2010爱思唯尔有限公司保留所有权利。
High back rounded vowels are prone synchronically to fronting in a fronting context and diachronically they are more likely to front than high front vowels are to retract. In order to shed light on the reasons for this back-front asymmetry, tense and lax vowels produced in three place of articulation contexts by seven first-language speakers of German at two speech rates were analysed physiologically, acoustically, and perceptually. An articulographic analysis showed greater magnitudes and peak velocities of horizontal tongue dorsum movement in CV transitions for /u:, o:/ than for /e:, i:/. A second experiment showed that the difference between tense and lax vowels in the tongue dorsum's horizontal position was greater for back than front vowels. A third experiment showed /u: U/ of were more likely to encroach on the /y:, Y/ spaces than the other way round for measurements based both on the horizontal tongue dorsum position and on spectral slope; a similar pattern of results emerged in a forced-choice perception experiment. The general conclusion is that high back vowels that are as peripheral as those in German have a high articulatory cost which may explain both the diachronic tendency for back vowels to front and why the absence of a high back vowel often contributes to asymmetric vowel distributions in the world's languages.
