以前的研究人员提出，语前聋的说话者不会移位舌体来建立元音稳定的姿势，并过度移位下巴。本研究的目的是评估三名聋人和两名听力成人说话者的开场手势舌位移位模式。电影透视和X射线微束数据表明，聋人受试者在打开手势时舌体发生了移位。然而，他们的舌头运动轨迹与听力受试者的不同。虽然听力受试者在不同的元音背景下舌头的移动方式不同，但聋人受试者在所有背景下都有相似的运动轨迹。共同的轨迹表明，一些聋人说话者收缩了他们的舌肌，使得舌体对所有元音的运动都是相似的。与听力受试者相比，失聪受试者在言语产生过程中的舌体似乎也不那么灵活。考虑了量化和比较聋人和听力说话者的语言行为的方法。
Previous researchers have proposed that prelingually deafened talkers do not displace the tongue body to establish vowel steady-state postures and displace the jaw excessively. The purpose of this investigation was to evaluate the opening gesture lingual displacement patterns of three deaf and two hearing adult talkers. Cinefluorography and x-ray microbeam data indicated that the deaf subjects displaced their tongue bodies during the opening gestures. However, their glossal movement trajectories were qualitatively dissimilar to those of the hearing subjects. Whereas the hearing subjects moved the tongue differently for different vowel contexts, the deaf subjects had similar trajectories for all contexts. The common trajectories suggest that some deaf talkers contract their tongue muscles such that the tongue body moves similarly for all vowels. The deaf subjects also appeared to have a less flexible tongue body during speech production than the hearing subjects. Means for quantifying and comparing the lingual behaviors of deaf and hearing talkers are considered.
