TwiML：动词 Gather 和 Pause 无效

Question

我正在使用 Twilio SDK (Java) 拨打美国手机号码，当用户接听电话时，我希望 TwiML 文件说出一条消息并获取用户按下的数字。但是 Twilio 似乎完全忽略了 TwiML 中的 Gather 和 Pause 动词。 Twilio 按预期拨打电话号码，但当用户接听电话时，Twilio 会背诵下面 TwiML 中的所有 Say 动词、Gather 和 Pause 没有任何效果，Twilio 会断开呼叫。此外，虽然 Say 动词指定了女性的声音，但 Twilio 使用男性声音来表示这些。

有没有办法让 Gather 和 Pause 在下面的 TwiML 中工作？有没有办法让 Say 语句使用女性的声音？ 请注意，我使用的是 Twilio 试用帐户。

<Response>
    <Say voice="woman">This is a courtesy phone call from YourCompany.</Say>

    <Say voice="woman">Please press one to buy our products.</Say>
    <Say voice="woman">Press two to be removed from our list.</Say>

    <Pause length="5" />

    <Gather timeout="60" numDigits="1" method="POST" action="http://twimlets.com/echo?Twiml=%3CResponse%3E%3CSay%3EHi+there.%3C%2FSay%3E%3C%2FResponse%3E" >
        <Pause length="30" />
    </Gather>

    <Say voice="woman">Goodbye.</Say>
</Response>

我从上面抓住了你的 TwiML 并掸掉了我的 Twilio-Java 设置（谢谢）！

package com.twilio;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

import com.twilio.sdk.verbs.TwiMLResponse;
import com.twilio.sdk.verbs.TwiMLException;

import com.twilio.sdk.verbs.Say;
import com.twilio.sdk.verbs.Gather;
import com.twilio.sdk.verbs.Pause;


public class StackOverflow extends HttpServlet {

    public void service(HttpServletRequest request, HttpServletResponse response) throws IOException {
        TwiMLResponse twiml = new TwiMLResponse();


        Gather gather = new Gather();
        gather.setTimeout(60);
        gather.setNumDigits(1);
        gather.setMethod("POST");
        gather.setAction("http://twimlets.com/echo?Twiml=%3CResponse%3E%3CSay%3EHi+there.%3C%2FSay%3E%3C%2FResponse%3E");
        Say sayInGather1 = new Say("This is a courtesy phone call from YourCompany.");
        sayInGather1.setVoice("alice");
        Say sayInGather2 = new Say("Please press one to buy our products.");
        sayInGather2.setVoice("alice");
        Say sayInGather3 = new Say("Press two to be removed from our list.");
        sayInGather3.setVoice("alice");
        Pause hanging = new Pause();
        hanging.setLength(30);
        Say sayInGather4 = new Say("Goodbye.");
        sayInGather4.setVoice("alice");

        try{
            gather.append(sayInGather1);
            gather.append(sayInGather2);
            gather.append(sayInGather3);
            gather.append(hanging);
            gather.append(sayInGather4);
            twiml.append(gather);
        } catch (TwiMLException e) {
            e.printStackTrace();
        }

        response.setContentType("application/xml");
        response.getWriter().print(twiml.toXML());
    }
}

所有 Servlet 代码都转换为以下 XML：

<Response>
  <Gather timeout="60" numDigits="1" method="POST" action="http://twimlets.com/echo?Twiml=%3CResponse%3E%3CSay%3EHi+there.%3C%2FSay%3E%3C%2FResponse%3E">
    <Say voice="alice">This is a courtesy phone call from YourCompany.</Say>
    <Say voice="alice">Please press one to buy our products.</Say>
    <Say voice="alice">Press two to be removed from our list.</Say>
    <Pause length="30"/>
    <Say voice="alice">Goodbye.</Say>
  </Gather>
</Response>
