Zero-shot dialogue understanding aims to enable dialogue to track the user's
needs without any training data, which has gained increasing attention. In this
work, we investigate the understanding ability of ChatGPT for zero-shot
dialogue understanding tasks including spoken language understanding (SLU) and
dialogue state tracking (DST). Experimental results on four popular benchmarks
reveal the great potential of ChatGPT for zero-shot dialogue understanding. In
addition, extensive analysis shows that ChatGPT benefits from the multi-turn
interactive prompt in the DST task but struggles to perform slot filling for
SLU. Finally, we summarize several unexpected behaviors of ChatGPT in dialogue
understanding tasks, hoping to provide some insights for future research on
building zero-shot dialogue understanding systems with Large Language Models
(LLMs).

本文研究了 ChatGPT 在零 - shot 语音理解和对话状态跟踪任务中的理解能力，并发现 ChatGPT 在对话状态跟踪任务中从多轮交互提示中获益，但在语音理解任务的信息填槽中存在困难。此外，我们总结了 ChatGPT 在对话理解任务中的一些意外行为，希望为未来建立基于大语言模型的零 - shot 对话理解系统提供一些见解。
