A device which provides visual feedback of vocal intensity, nasalization, or a ratio of nasalization to vocal intensity, is described. The device was used in several experiments in which control of vocal intensity was a necessary component. Normal and hypernasal speakers were able to control their vocal intensities successfully when using the visual display. The display also was used in an experiment designed to determine how well normal speakers can manipulate their nasalization without visual feedback and whether they improve when feedback is provided. Subjects manipulated their nasalization first without feedback, then with feedback, then, again, without feedback. The subjects' performance improved when feedback was provided and determined when feedback was removed. It appears that this device is useful for many applications in a variety of settings.
描述了一种能够提供声音强度、鼻音化或鼻音化与声音强度之比的视觉反馈的装置。该装置在几个实验中被使用，在这些实验中，声音强度的控制是一个必要的组成部分。正常发声者和鼻音过重的发声者在使用视觉显示器时能够成功控制他们的声音强度。该显示器还被用于一项实验，该实验旨在确定正常发声者在没有视觉反馈的情况下能够多好地控制他们的鼻音化，以及当提供反馈时他们是否会有所改善。受试者首先在没有反馈的情况下控制他们的鼻音化，然后在有反馈的情况下进行控制，接着再次在没有反馈的情况下进行控制。当提供反馈时，受试者的表现有所改善，并在去除反馈时确定了这一点。看来这种装置在各种环境中的许多应用中都是有用的。
