Stuttering still has no known cause or causes. We hypothesize, on the basis of speech phonation in normal and abnormal cases, that it could be due to developmental incompetence of the velopharyngeal isthmus. With continued cortical imposition of normality on this incompetent isthmus, phonetic aberration, such as stuttering, results. We suggest that palatal rise or a cervical collar be used so as to hyperextend the neck and adequately correct this articulatory deficit.
口吃的病因仍然不明。基于正常和异常情况下的言语发声，我们推测，口吃可能是由于腭咽峡发育不全所致。随着大脑皮层持续将正常状态强加于这个功能不全的峡部，就会产生诸如口吃之类的语音畸变。我们建议使用软腭上抬或颈圈，以使颈部过度伸展，并充分纠正这种发音缺陷。
