Question

我正在使用Alexa技能套件来开发Alexa技能，当用户说出无效的语音时，它会回答“所请求的技能的响应存在问题”。

我已经尝试过使用AMAZON.Fallback意图，但是在测试窗口中查看json输出表明它尚未被触发。

我的后端是Lambda中的python 2.7，我正在使用语言环境en-gb（我尝试将交互模型复制到en-us中，但结果相同）。

回退意图是用于处理无效话语的正确方法，还是有另一种方式来获得类似的结果？

这是Json输入：

如果您所使用的英语或德语技能是肯定的，则应使用后备意图。其他语言环境尚不支持。对于en-GB或en-US，您需要确保在语音交互模型（前端）中定义了AMAZON.FallbackIntent，并且在后端（例如lambda）中有一个处理程序来捕获意图请求名为AMAZON.FallbackIntent 在回退过程中，这肯定听起来像是一个问题（您可能无法正确捕捉）

Alexa技能套件后备意图无法调用
