With the advent of speech transmission over the internet, impairments such as delay and packet loss affect the conversation behavior of the interlocutors. As an example, end-to-end delay affects turn-taking and packet loss degrades intelligibility of the transmitted messages. Thus, both types of impairments provoke follow-up requests, meta communication and barge-in, and degrade perceived quality by influencing conversation behavior.It is the aim of the present research project to describe the conversation behavior of two interlocutors who communicate via an impaired telephone channel using formal models, and hereby make it accessible to an automatic simulation. Agenda-based models which are successful in human-machine interaction are transferred to human-human dialogues and augmented with descriptions of turn-taking with delayed transmission and misunderstanding handling due to packet loss. The simulation is carried out on the levels of text, intonation, semantics and pragmatics using linguistic material from conversation tests. During the simulation, new conversations are generated based on this material dependent on the transmission channel delay and packet loss. Simulated dialogues are then compared to empirically-observed ones for evaluation purposes. A model for predicting conversation quality is derived from these data. The simulation approach is thus not only useful for research into basic aspects of human communication behavior, but can also be used for quality engineering of communication networks.

随着互联网语音传输的出现，诸如延迟和分组丢失等损害影响了对话者的会话行为。例如，端到端延迟会影响话轮转换，数据包丢失会降低传输消息的可理解性。因此，这两种类型的障碍引起后续的请求，Meta通信和闯入，并降低感知质量，通过影响会话behavior.It的目的是本研究项目描述的对话行为的两个对话者谁通过受损的电话信道使用正式的模型进行通信，从而使其访问的自动模拟。将在人机交互中取得成功的会话模型转化为人机对话，并对由于丢包引起的话轮转换延迟和误解处理进行了描述。模拟是在语篇、语调、语义和语用四个层面上进行的，使用的语言材料来自会话测试。在模拟过程中，新的会话生成的基础上，该材料依赖于传输信道延迟和数据包丢失。然后将模拟的对话与模拟观察的对话进行比较，以进行评估。从这些数据中推导出一个用于预测会话质量的模型。因此，仿真方法不仅是有用的人类通信行为的基本方面的研究，但也可以用于通信网络的质量工程。
