Speech rate convergence has been reported previously as a phenomenon in which one's speech rate is influenced by his/her partner's speech rate. This phenomenon has been demonstrated in artificial settings, and to some extent, in mother-child interactions. The purpose of this study was to explore speech rate adjustment in a quasi-natural adult-adult conversation.
An A-B-A-B paradigm was used, in which ten adults conversed on a given topic with two experimenters. Speech rates of both communication partners were measured.
Participants significantly reduced their speech rate, in response to the experimenters' reduction in speech rate. However, the participants' reduction in speech rate was significantly smaller than the experimenters' reduction in speech rate. In addition, during the controlled slow speech rate, the participants' speech rate correlated negatively with that of the experimenters'.
Results suggest that speech rate convergence is a non-linear phenomenon, and may be affected by various linguistic as well as communicational factors. From a clinical perspective, the results support the use of the modeling strategy in speech therapy, as a means to facilitate a reduction in clients' speech rate.
语速趋同此前被报道为一种现象，即一个人的语速会受到其对话伙伴语速的影响。这种现象已在人工环境中得到证实，并且在某种程度上也在母子互动中得到了证实。本研究的目的是探讨在准自然的成人对成人对话中语速的调整情况。
采用A-B-A-B范式，其中十名成年人就给定话题与两名实验者进行对话。测量了双方交流伙伴的语速。
参与者显著降低了他们的语速，以回应实验者语速的降低。然而，参与者语速的降低明显小于实验者语速的降低。此外，在控制的慢语速期间，参与者的语速与实验者的语速呈负相关。
结果表明语速趋同是一种非线性现象，可能受到各种语言以及交流因素的影响。从临床角度来看，这些结果支持在言语治疗中使用模仿策略，作为促进患者语速降低的一种手段。
