Question

我正在使用Twilio，借助电话号码和网络挂钩将呼叫转发到本地Node.js应用程序。 Ngrok用于将呼叫通过http端口1337转发到本地运行的Node.js应用程序。
调用将正确转发到本地应用程序，并带有默认的传出响应。但是，当twiml.gather将请求转发到fact-command块时，语音识别代码不起作用。

代码如下：

const http = require('http');
const VoiceResponse = require('twilio').twiml.VoiceResponse;

http
  .createServer((req, res) => {
    // Create TwiML response
    const twiml = new VoiceResponse();

    // twiml.say('Hello from your pals at Twilio! Have fun.');
    twiml.gather({
      input: 'speech',
      timeout: 3,
      hints: 'cat, numbers, chuck norris',
      action: '/fact-command'    // Route to a twilio Speech Recognition event handler
    }).say('Welcome to the Twilio Facts hotline. Please say cat for cat facts, number for trivia about numbers, or chuck norris for a random chunk of chuck norris knowledge.');

    res.writeHead(200, { 'Content-Type': 'text/xml' });
    res.end(twiml.toString());


    var url = req.url;
    if(url ==='/fact-command'){
        console.log("This is a Twilio route");
        exports.handler = function(context, event, callback) {
          const twiml = new Twilio.twiml.VoiceResponse();

          const command = event.SpeechResult.toLowerCase();

          twiml.say(`You said ${command}. I'll give you a ${command} fact.`); // Speech is not getting recognized

          callback(null, twiml);
        };

    }

  })
  .listen(1337, '127.0.0.1');

console.log('TwiML server running at http://127.0.0.1:1337/');

如何使用TwiML和本地Node.js应用程序识别语音并将其存储在变量中？

TwiML语音识别在本地Node.js应用程序中不起作用
