Lateral cineradiograms, taken at a rate of 100 frames per second, were used to investigate tongue apex movements associated with alveolar consonants produced by five American English speakers. Consistent with previous research concerning bilabial stops, the results indicated a tendency for faster apical movements towards voiceless stops than toward voiced stops. On the other hand, tongue speeds during voiced alveolar stops and alveolar taps did not appear to differ significantly. Any tendency for faster speeds to be associated with tap movements appeared to be due to corresponding greater distances moved by the tongue tip. Finally, the amount of stress on vowels preceding or following [d] was not found to be an independent factor for determining tongue tip speeds toward the consonant. Once again, any speed differences seemed predictable on the basis of distance.
以每秒100帧的速率拍摄的侧面X线电影摄影用于研究与五位美式英语使用者发出的齿龈辅音相关的舌尖运动。与先前关于双唇塞音的研究一致，结果表明舌尖朝着清塞音的运动往往比朝着浊塞音的运动更快。另一方面，浊齿龈塞音和齿龈闪音期间的舌速似乎没有显著差异。任何与闪音运动相关的更快速度的趋势似乎是由于舌尖移动的相应更大距离。最后，发[d]音之前或之后的元音的重音程度并未被发现是决定舌尖朝向该辅音的速度的一个独立因素。再一次，任何速度差异似乎都可以根据距离来预测。
