我有一个Alexa技能，在那里我有多个意图。这些意图是使用自定义广告位值调用的，这些自定义广告位值大多采用是/否答案。问题是，随后的是/否插槽值始终引用最后一个意图，因此它永远不会超过第一个意图。有没有一种方法可以重置插槽值？ 任何帮助将不胜感激。

答案 0 :(得分：0)
您需要进行交互模型设计。您不应使用自定义的YesIntent和NoIntent，而应使用预定义的AMAZON.YesIntent和AMAZON.NoIntent。
如果从您的交互模型中我了解到，您仅需要两个插槽model和variant。
考虑一下这种方式：
[TestDriveIntent]
start a test drive
I want a test drive
start a test drive on {model}
begin test drive on {model} {variant}
其中{model}和{variant}是实现您的意图所需的两个位置。启动此对话框后，您可以委派或获取要填充的这些插槽。您还可以使用ConfirmSlot和ConfirmIntent指令在继续操作之前从用户那里获得确认。这样做的好处是，您不必处理用户对这些确认的“是”和“否”输入。
