本研究探讨了其他说话者的存在如何影响与口语对话系统的互动。我们分析了参与者的语音的几个语音特征，即，基频、强度和发音率，在两种情况下：有和没有来自人类同盟者作为第三对话者的额外语音输入。通过参与者使用商业语音助手在两种条件下交替执行的任务进行了比较。我们比较了两种情况下的特征分布，以研究当涉及邦联时，说话者的行为是否不同。时间分析揭示了特征产生中的连续变化。特别是，我们在整个交互过程中测量了参与者和系统之间的整体适应性。结果显示，在大多数情况下，三个功能中的两个功能存在显着差异，在用户首次单独与设备交互的情况下，差异更为明显。我们还分析了执行的任务，参与者性别和任务顺序等因素，为参与者的行为提供了额外的见解。
This study examines how the presence of other speakers affects the interaction with a spoken dialogue system. We analyze participants’ speech regarding several phonetic features, viz., fundamental frequency, intensity, and articulation rate, in two conditions: with and without additional speech input from a human confederate as a third interlocutor. The comparison was made via tasks performed by participants using a commercial voice assistant under both conditions in alternation. We compare the distributions of the features across the two conditions to investigate whether speakers behave differently when a confederate is involved. Temporal analysis exposes continuous changes in the feature productions. In particular, we measured overall accommodation between the participants and the system throughout the interactions. Results show significant differences in a majority of cases for two of the three features, which are more pronounced in cases where the user first interacted with the device alone. We also analyze factors such as the task performed, participant gender, and task order, providing additional insight into the participants’ behavior.
