Alexa忽略了“到达”样本话语并映射到错误的意图

Question

我为Alexa Skill，NextTrainIntent和TrainArrivalIntent设置了两个意图。在我的示例话语中，我将它们映射为：

NextTrainIntent what is the next train to {DestinationCity}
NextTrainIntent what's the next train to {DestinationCity}
NextTrainIntent when is the next train to {DestinationCity}
NextTrainIntent when is the next train from {OriginCity}
NextTrainIntent when is the next train from {OriginCity} to {DestinationCity}
NextTrainIntent when is the next train
TrainArrivalIntent when does train {TrainNumber} arrive at {DestinationCity}
TrainArrivalIntent when does train {TrainNumber} arrive 
TrainArrivalIntent when does train {TrainNumber} get in 
...

当我使用亚马逊的服务模拟器测试时，如果我输入以下话语作为文本：“何时列车9306到达”，服务请求json显示它已将话语映射到NextTrainIntent，即使它是完全匹配的TrainArrivalIntent的示例话语：

"request": {
  "type": "IntentRequest",
  "requestId": "EdwRequestId.ccafa51d-38de-4500-b17b-f94bbee1ad93",
  "intent": {
    "name": "NextTrainIntent",

但是，如果我测试话语：“火车9305什么时候进入”，它会正确映射到TrainArrivalIntent。

"request": {
  "type": "IntentRequest",
  "requestId": "EdwRequestId.7a415e55-14b3-4789-9a83-0f6cf2f16a6c",
  "intent": {
    "name": "TrainArrivalIntent",

这有什么不对？在这种情况下，单词“到达”的存在对于辨别两个意图是至关重要的。然而，Alexa似乎忽略了它。如何让它“到达”得到使用？

Answer 1

我从我的样本中删除了“what is the”和“when is”语句，并开始工作。

NextTrainIntent next train from {OriginCity} to {DestinationCity}
NextTrainToFromIntent next train to {DestinationCity} from {OriginCity}
TrainArrivalIntent train {TrainNumber} arrive at {DestinationCity}
TrainArrivalIntent train {TrainNumber} arrive 
TrainArrivalIntent train {TrainNumber} get in 
TrainArrivalIntent train {TrainNumber} arrive at {DestinationCity}
TrainArrivalIntent train {TrainNumber} get in to {DestinationCity}
TrainArrivalIntent train number {TrainNumber} arrive at {DestinationCity}
TrainArrivalIntent train number {TrainNumber} get in to {DestinationCity}
TrainArrivalIntent train number {TrainNumber} arrive 
TrainArrivalIntent train number {TrainNumber} get in

因为上面的语音样本还有一些其他变化，我不肯定删除问题前缀是解决问题的原因。与机器学习一样，你经常无法得到“为什么”有效的答案。无论是什么原因，上述样本话语确实使问题中的话语得到了恰当的认可。
