azure - 如何在音频末尾获取 'synthesisCompleted'？ (微软 azure TTS)

Question

我正在研究这个使用的示例(https://github.com/Azure-Samples/cognitive-services-speech-sdk/blob/master/quickstart/javascript/browser/text-to-speech/index.html) Microsoft Azure 语音服务，用于将文本转换为语音。
我想要的是在语音结束时获取一个事件，以便我可以做其他事情。现在它向我发送了一个事件(“synthesisCompleted”事件)，该事件应该在演讲结束时触发，但实际上它是更早发送的(就像我不知道如何捕获音频的结尾一样。

有人可以帮助我吗？我不知道它是否有帮助，但我看到“speakTextAsync”中还有一个“stream”参数。

我终于知道怎么做了。如果其他人也需要解决方案，这是我的职责:

    var SpeechSDK;

    function textToSpeech(txt){
      var player = new SpeechSDK.SpeakerAudioDestination();
      player.onAudioEnd = function (_) {
          ##do something##
        };
      var audioConfig  = SpeechSDK.AudioConfig.fromSpeakerOutput(player);
      const speechConfig = SpeechSDK.SpeechConfig.fromSubscription(CONFIG.voiceSubKey, CONFIG.voiceLoc);  
      speechConfig.speechSynthesisOutputFormat = "***";
      speechConfig.speechSynthesisLanguage = CONFIG.voiceLan;
      speechConfig.speechSynthesisVoiceName = CONFIG.voiceName;
      
      var synthesizer = new SpeechSDK.SpeechSynthesizer(speechConfig, audioConfig);
      
      const complete_cb = function (result) {
        if (result.reason === SpeechSDK.ResultReason.SynthesizingAudioCompleted) {
          console.log("synthesis finished");
        } else if (result.reason === SpeechSDK.ResultReason.Canceled) {
          console.log("synthesis failed. Error detail: " + result.errorDetails);
        }
        synthesizer.close();
        synthesizer = undefined;
      };
      const err_cb = function (err) {
        window.console.log(err);
        synthesizer.close();
        synthesizer = undefined;
      };

      synthesizer.synthesisStarted  = function (s, e) {
        console.log("Speech started");
      };
      synthesizer.speakTextAsync(txt,
        complete_cb,
        err_cb);
           
    } 
       
    if (!!window.SpeechSDK) {SpeechSDK = window.SpeechSDK;}
