It has been shown that visual display systems of intonation can be employed beneficially in teaching intonation to persons with deafness and in teaching the intonation of a foreign language. In this paper, the question is addressed whether important audible differences between two pitch contours correspond with visually conspicuous differences between displayed pitch contours. If visual feedback of intonation is to be effective in teaching situations, such correspondence must exist. In two experiments, phoneticians rated the dissimilarity of two pitch contours. In the first experiment they rated the two pitch contours auditorily (i.e., by listening to two resynthesized utterances). In the second, they rated the same two pitch contours visually (i.e., by looking at the two contours displayed on a computer screen). The results indicate why visual feedback may be very effective in intonation training if pitch contours are displayed in such a way that only auditorily relevant features are represented.
研究表明,语调的视觉显示系统可有效地用于对聋人进行语调教学以及外语语调教学。本文探讨的问题是,两个音高轮廓之间重要的听觉差异是否与所显示的音高轮廓之间在视觉上明显的差异相对应。如果语调的视觉反馈要在教学情境中有效,这种对应关系必须存在。在两项实验中,语音学家对两个音高轮廓的差异程度进行了评级。在第一个实验中,他们通过听觉对两个音高轮廓进行评级(即通过聆听两个重新合成的话语)。在第二个实验中,他们通过视觉对相同的两个音高轮廓进行评级(即通过查看计算机屏幕上显示的两个轮廓)。结果表明,如果以仅呈现听觉相关特征的方式显示音高轮廓,那么视觉反馈在语调训练中可能会非常有效。
