在带有元音辅音的元音-辅音-元音(VCV)序列中,循环是众所周知的椭圆形舌尖路径。然而,关于空气动力学、主动运动控制和生物力学对环路的相对影响的讨论是有争议的。为了表征生物力学的影响,本研究的设计是基于不涉及辅音的V1-V2-V1序列,通过电磁关节成像(EMA)记录。在此背景下,我们发现了环状形状随着元音V1和V2之间的主移动线的角度而系统地变化的证据。此外,对11名男性和7名女性德国成年人在不同的说话速度(正常和缓慢)和下颌活动度(大、小和无咬块)的情况下,检查了环状形状的规律性角度相关性。模型模拟表明,舌环及其形状的角度相关性均可归因于舌外肌肉的生物力学特性。
Loops are well known as the elliptical tongue fleshpoint paths in vowel-consonant-vowel (VCV) sequences with a velar consonant. However, the discussion about the relative influences of aerodynamics, active motor control and biomechanics on loops is controversial. In order to characterize the biomechanical influence, the design of the current study was specifically based on V1-V2-V1 sequences with no consonants involved, recorded by means of electromagnetic articulography (EMA). In this context, we found evidence that the loop shape varies systematically with the angle of the main movement line between the vowels V1 and V2. Moreover, the regular angle-dependence of the loop shape is examined for eleven male and seven female German adults under different conditions for speaking rate (normal and slow) and for jaw mobility (large, small and no bite block). Model simulations suggest that both the loops and the angle-dependence of their shape can be attributed to biomechanical properties of the extrinsic tongue muscles.
