We present data on velar speech movements examined by electromagnetic articulography (EMA), a tool for the study of velar kinematics. Based on investigations on 22 normal German subjects (15 male, 7 female), movement paths of the velum using a sensor positioned on the midsagittal anterior surface were recorded using a series of high and low vowel VCV utterances. Maximum velar elevation (mean = 13.5 +/- 0.6 mm [SD]) with the rest position as a reference was observed during the production /iti/. The average maximum articulatory velocity of velar movements during /iti/ production was 141.0 mm/sec. Maximum movement of the velum observed during production of /ana/ averaged 7.5 +/- 1.1 mm. The direction of velar movement ranged between 44.6 degrees and 50.4 degrees relative to the bite plane registered electromagnetically. The influence of loudness variation of sequence production is demonstrated and discussed with the literature.
我们展示了通过电磁关节造影术（EMA）检测到的软腭语音运动数据，EMA是一种用于研究软腭运动学的工具。基于对22名正常德国受试者（15名男性，7名女性）的研究，使用位于矢状面中前部表面的传感器，通过一系列高低元音VCV发音记录软腭的运动轨迹。以静止位置为参考，在发/iti/音时观察到软腭最大抬高（平均值 = 13.5 +/- 0.6毫米[标准差]）。发/iti/音时软腭运动的平均最大发音速度为141.0毫米/秒。发/ana/音时观察到的软腭最大运动平均为7.5 +/- 1.1毫米。相对于通过电磁记录的咬合平面，软腭运动方向在44.6度至50.4度之间。文中展示并讨论了序列发音响度变化的影响，并与文献进行了比较。
