描述了一种视觉俯仰显示器。它通过低通滤波提取基频，并在存储示波器上显示频率作为时间的函数。三项研究与聋哑儿童的描述。在第一，它被发现的主题有穷人自愿音高控制，尽管一般良好的口语技能。在第二，它表明，简单的间距控制可以快速学习与使用的视觉显示。然而，传统的非仪器技术被发现几乎同样有效。在第三项研究中，一名深度失聪的女孩学习控制语域，并在单词和句子中产生可接受的语调模式。不幸的是，这对她的日常交际语言没有直接的影响。建议未来的聋人言语处理辅助工具的设计者应该注意到这些发现的两个含义：1）工具技术可能提供很少或没有优势，适当应用传统技术的某些技能的教学;和2）修改儿童的交际行为的过程是一个复杂的，其中的技术援助只发挥有限的作用。除非将语音处理辅助工具的使用以有意义的方式纳入有效的总体计划，否则其益处可能微乎其微。
A visual pitch display is described. This extracts fundamental frequency by low-pass filtering and displays frequency as a function of time on a storage oscilloscope. Three studies with deaf children are described. In the first it is found that the subjects have poor voluntary pitch control, despite generally good oral skills. In the second it is shown that simple pitch control can be learned quickly with the use of the visual display. However, traditional noninstrumental techniques are found to be almost as effective. In the third study, a profoundly deaf girl learns to control voice register and to generate acceptable intonation patterns within words and sentences. Unfortunately, this has no immediate effect on her everyday communicative speech. It is suggested that would-be designers of speech processing aids for the deaf should take note of two of the implications of these findings: 1) instrumental techniques may offer little or no advantage over properly applied traditional techniques for the teaching of certain skills; and 2) the process of modifying a child's communicative behavior is a complex one in which the technical aid has only a limited role to play. Unless use of the speech processing aid is incorporated in a meaningful way into an effective total program, its benefits are likely to be minimal.
