关于Utterance意思的理解

在对话系统中,Utterance可谓得上是必考词,基本上所有的涉及对话的文章都会是用这个词,但是是什么啥意思呢?

首先,我们查询Collins得到的结果是这样子的:

utterance

  1. [可数] Someone's utterances are the things that they say.
  2. [不可数]Utterance is the expression in words of ideas, thoughts, and feelings.

我们可以明白,一个人了说出的话就是utterance。但不过如果照搬这个翻译到文章里的话,还是会让人丈二和尚摸不着头脑。

然后,再让我们看看WIki的解释

In spoken language analysis, an utterance is the smallest unit of speech. It is a continuous piece of speech beginning and ending with a clear pause.

画重点,ending with a clear pause,所以说一个utterance就是你叽叽歪歪说一大堆,直到说完停止等待对方回应的过程。尽管人说话不总是你说一句我说一句,轮流来这样子,但不过大多数情况满足的。因为QA中,对话几乎都是你一轮我一轮的,所以引入了utterance这个术语。

很多时候,utterance可以理解为问答双方的每一轮的提问/回答,一个utterance可能由多个句子组成。比如领导开会,讲了几个小时,下面的同学回答 "嗯",这两个都是utterance 。
