This study investigates if and to what extent speakers change their vowel production after interacting with someone from a different dialect region. Phonetic accommodation was investigated for 14 mixed-dialect pairs in Swiss German. Vowels for each speaker pair were analysed acoustically before and after they interacted for about 20 minutes. Agent-based modelling was used to simulate the change in absence of social and interactional factors. The simulation predicted that convergence was not symmetric but depended on a vowel's variability and its orientation in the acoustic space prior to the interaction. No evidence of convergence was found for the accommodation study involving 14 real interactions. The lack of convergence is explained with reference to the specific sociolinguistic situation of German-speaking Switzerland, where dialects carry a high prestige and are mutually intelligible, and where mixed-dialect interactions are the norm.

这项研究调查了说话者在与来自不同方言区域的人互动后是否以及在多大程度上改变了他们的元音产生。对 14 对瑞士德语混合方言的语音适应进行了调查。在他们互动大约 20 分钟之前和之后，对每个扬声器对的元音进行了声学分析。基于代理的建模被用来模拟在缺乏社会和交互因素的情况下的变化。模拟预测收敛不是对称的，而是取决于元音的可变性及其在相互作用之前的声学空间中的方向。对于涉及 14 个真实交互的调节研究，没有发现收敛的证据。参考德语瑞士的特定社会语言学情况来解释缺乏趋同性，
