如何向 Amazon Alexa Skills Kit (ASK) 混合字符串和数字输入？

我正在尝试创建一个 Amazon Alexa 技能套件来进行某种自动化，这需要接受由字符串和数字组成的语音输入（a-test12fish).

当我在 Alexa Skills Kit 中使用自定义插槽时，它不允许我键入带有数字的字符串。当我尝试输入时ask alexa, dangerZone find a-test12fish，我收到以下错误：

错误：文本输入无效。文本应以字母开头，并且只能包含字母、空格、句点或撇号

我怎样才能克服这个错误？

这是一个解决方案。

您可能不想在意图模式中完成此操作。相反，请尝试使用 Node.js 创建自定义模式，将字母、数字和符号编译为单个响应。这是我对字母数字输入模式的演绎。请注意：我只是为了回答您的问题而写下此内容，尚未在更大的技能中对其进行测试。话虽如此，我已经取得了巨大的成功MODES当我有机会时，我一定会用自己的技能来实现这一点。

这段代码背后的想法是，你将用户推入一个单独的模式，忽略除NumberIntent, LetterIntent, SymbolIntent，以及一些帮助功能。用户快速输入他们的字母数字值，完成后激活 CompletedIntent。然后，该字母数字值可以在您的技能中的其他地方使用。如果您还没有使用过Modes请注意，完成或退出后，您将被重定向回LOBBYMODE您可以在其中继续访问您技能中的其他意图。

    'enterPasswordIntent': function () {

      this.handler.state = states.PASSWORDMODE;
      message = ` You will now create a password one letter, number or symbol at a time.  there will be no message after each entry.  simply wait for alexa's ring to become solid blue then stay your next value.  When you are satisfied say complete. Begin now by saying a number, letter, or keyboard symbol. `;
      reprompt = `Please say a number letter or symbol`;
      this.emit(':ask', message, reprompt);
    },
