twilio函数读取多个语音输入

该用例是在twilio中使用可编程语音调用ivr系统。基于ivr问题,使用twilio函数和twiml发送答案。我怎样才能做到这一点?到目前为止,我已经使用twilio进行了调用,并在回调webhook下面进行了引用。

 [HttpPost]
    public TwiMLResult Index(string message)
    {
        var response = new VoiceResponse(); 

        var gather = new Gather(input: new List<Gather.InputEnum>()
        {
            Gather.InputEnum.Speech
        } , 
            timeout: 5,  action:new Uri("https://url-sample/GatherSample"));

        gather.Say("Please press 1 or say sales for sales.");
        response.Append(gather);
        LogWriter.Debug($"Message : {response.ToString()}");
        return new TwiMLResult(response);
    }

还有斜纹功能代码。

    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.`);

  callback(null, twiml);
};
