Abstract

New dialog promoting methods for voice storage dialog systems are discussed. The paper describes two hypotheses that attempt to put at ease those callers who hesitate or are shy by designing an interactive dialog or offering attractive information to the caller. The following two hypotheses are introduced. The first is the less information per utterance required by the system, the more comfortable the user feels. The second is the more attractive the information is that is given after an utterance by the system, the more the caller will want to have a message. The experimental conditions are explained to evaluate the previous hypotheses using an opinion score. The system consists of a PC, telephone line interface board, and control software. For eliminating the effect of recognition accuracy, dialogs are designed without speech recognition. Finally, the experimental results are described which indicate the usefulness of each hypothesis, and in addition these results show an increase of 0.7-0.8 points in a mean opinion score.<>

语音对话系统中的话语提升方法

讨论了语音存储对话系统中新的对话提升方法。这篇论文描述了两种假设，它们试图通过设计一个互动对话或向呼叫者提供有吸引力的信息来让那些犹豫或害羞的呼叫者放松下来。介绍了以下两个假设。首先，系统每句话需要的信息越少，用户感觉就越舒服。第二，系统发出的信息越吸引人，呼叫者就越想要留言。解释实验条件，以评估先前的假设使用意见评分。该系统由PC机、电话线接口板和控制软件组成。为了消除对识别精度的影响，在设计对话框时不进行语音识别。最后，对实验结果进行了描述，说明了每个假设的有效性，并且这些结果表明平均意见得分增加了0.7-0.8分
