c# - Twilio语音识别无法在c#中记录语音结果

问题描述

我正在尝试使用 Twilio 可编程语音编写一个应用程序，以便能够从客户那里收集语音和数字。我的代码正在获取数字但没有响应语音结果。顺便说一句，在最新版本的 Twilio 中，'gather' 的'input' 参数不允许将“dmfs speech”字符串放在一起使用这两个选项，因为它只接受带有 Dtmf 和 Speech by 的 [InputEnums] 列表定义。如果有人可以帮助我找出我做错了什么，这是我的代码示例：

 public List<InputEnum> inputEnum = new List<InputEnum>() {InputEnum.Speech , InputEnum.Dtmf};  // creating a list with Dtmf and Speech options 

    var gather = new Gather(input: inputEnum, action: new Uri(baseUri,"IVR/MainMenu"), hints: "returning customer , agent", timeout: 4, numDigits: 1);

   gather.Say("If you are a returning customer and would like to place your last order, say returning customer or press 1." );
   gather.Say("To speak to an agent, say agent or press 2");

  _response.Append(gather);

    return new TwiMLResult(_response.ToString());
    }


 [HttpPost]
    public ActionResult MainMenu(string digits)
    {

        if ((digits == "1") || ( digits == "returning customer"))
        {                 
            _response.Say("Please hold while we pull up your information.");
            _response.Pause(6);

            var gather = new Gather(input: inputEnum, hints: "last order, place last order , agent", timeout: 4, action: new Uri(baseUri, "IVR/ReturnInstructions"), numDigits: 1);
            gather.Say("If you would like us to read your last order to you, say last order or press 1");
            gather.Say("To place your last order, say place last order or press 2");
            gather.Say("To speak to an agent, say agent or press 0");
            _response.Append(gather);

            return new TwiMLResult(_response.ToString());

        }

解决方案

我尝试了不同的方法，结果我必须将另一个专门用于语音结果的参数传递给我的操作，并确保将其转换为小写，否则它将始终返回 false 到字符串比较。这是我的 MainMenu ActionResult 的示例：

public ActionResult MainMenu(string digits = null, string speechresult = null)
    {
        if ((digits == "1") || (speechresult != null && speechresult.ToLower() == "returning customer"))
        {
            _response.Say("Please hold while we pull up your information.");
            _response.Pause(6);
            gather.Say("If you would like us to read your last order to you, say last order or press 1");
           return new TwiMLResult(_response.ToString()); 
        }
        else if ((digits == "0") || (speechresult != null && speechresult.ToLower() == "agent"))
        {
            return connectToAnAgent();
        }

        return connectToAnAgent();
    }
