Each individual has a unique mental tempo (referred to as personal tempo), and the alignment of this tempo plays a crucial role in facilitating smooth interactions with spoken dialogue systems. This study focuses on the “switching pause,” a key component of conversational tempo that is established during interaction. Using a dialogue corpus, we analyzed the impact of switching pauses on dialogue and the process of synchronization. Through the analysis of synchronization between pairs, we examined dialogues with high similarity in switching pauses to elucidate the impact of this synchronization on goal achievement and cooperativity in dialogue. Furthermore, we conducted a time-series analysis within pairs to investigate the synchronization process and proposed a method for determining switching pauses for implementation in dialogue systems. These findings contribute significantly to the investigation of individual differences in users and the identification of personal factors that enable effective dialogue with dialogue systems
