Tongue movement during production of the speech sounds /a/, /i/, and /k/ was examined with a real-time sector scanner positioned submentally. With this technique, it is possible to obtain excellent visualization of the tongue surface and to identify much of the intrinsic soft tissue anatomy of the tongue and floor of the mouth. Tongue movement and configuration were found to be consistent for 10 normal speakers, especially for /i/ and /k/. Three patients with neurological disease and dysarthria showed varying but significant differences in articulation compared to normals. It appears that real-time ultrasound imaging of the oral cavity is a potentially valuable technique for the clinical investigation of normal and abnormal speech.
使用置于颏下的实时扇形扫描仪检查发语音/a/、/i/和/k/时的舌运动。通过这种技术，可以很好地观察舌表面，并识别舌和口腔底部的许多内在软组织解剖结构。发现10名正常受试者的舌运动和形态是一致的，尤其是发/i/和/k/音时。与正常人相比，3名患有神经疾病和构音障碍的患者在发音上表现出不同但显著的差异。看来口腔实时超声成像对于正常和异常言语的临床研究是一种潜在有价值的技术。
