摘要
在模拟的语音超文本系统中,以链接词检测率和句子理解正确率为指标,探讨了语音超文本系统中非言语相关标记声与链接词的相对时相及标记声的持续时间对作业绩效的影响,旨在为语音超文本界面中非言语相关标记的设计提供适宜的参数。结果发现:(1)非言语标记声与链接词所含元素的相对时相显著地影响了链接词的检测绩效,尾字标记的绩效最佳,全词标记次之,首字标记最差,但三种标记方式对句子的理解无显著影响;(2)在50ms-100ms内,非言语标记声的持续时间对链接词的检测和句子理解均无显著影响。根据本实验的结果,笔者推荐尾字标记作为语音超文本设计中适宜的非言语相关标记方式。
In order to provide ergonomic parameters for the design of non-speech-related marking, this study investigated the effects of the duration and the phase of non-speech-related marking sound relative to the anchor on the detectability and comprehensibility of the non-speech-related marking in a simulated audio-hypertext system.. The results showed that: (1)The detectability of the last-character marking was higher than that of the whole-word, and the first-character marking had the worst detectability. However, there was no difference in comprehensibility under the three different conditions. (2) Within 50ms--100ms, the duration of the non-speech-related marking had no effect on detectability or comprehensibility. Based on these results, we hold that in an audio-hypertext system, the last-character marking is superior to the other non-speech-related marking methods.
