在Dialogflow的训练短语中出现问题时，使用问号的最佳做法是什么-是否应该使用它们？
我的观察是，如果我添加带有问号的训练短语（例如“天气如何？”），那么有时没有问号的相同用户句子将不会被视为特定意图。另一方面，当我添加不带问号的训练短语时，无论使用什么问号，它们都会被正确识别。
示例1
Training phrase: "What is the weather?"
User question: "What is the weather?" (recognized)
User question: "What is the weather" (not recognized)
示例2
Training phrase: "What is the weather"
User question: "What is the weather?" (recognized)
User question: "What is the weather" (recognized)
