谷歌文本到语音播放与我的扬声器

Question

我想要一个文本作为输入，用我电脑的扬声器将该文本的内容复制为合成语音。我正在开发的应用程序Java，为了得到想要的结果，我正在使用谷歌测试到语音库。我从以下代码开始：https://cloud.google.com/text-to-speech/docs/reference/libraries

但正如你所见，语音信息保存在文件中，而不是用扬声器复制。所以我的问题是，我如何用运行应用程序的计算机的扬声器重现语音信息？

import com.google.cloud.texttospeech.v1.AudioEncoding;
import com.google.cloud.texttospeech.v1.SsmlVoiceGender;
import com.google.cloud.texttospeech.v1.SynthesisInput;
import com.google.cloud.texttospeech.v1.SynthesizeSpeechResponse;
import com.google.cloud.texttospeech.v1.TextToSpeechClient;
import com.google.cloud.texttospeech.v1.VoiceSelectionParams;
import com.google.protobuf.ByteString;
import java.io.FileOutputStream;
import java.io.OutputStream;


public class QuickstartSample {

  public static void main(String... args) throws Exception {
    // Instantiates a client
    try (TextToSpeechClient textToSpeechClient = TextToSpeechClient.create()) {
      // Set the text input to be synthesized
      SynthesisInput input = SynthesisInput.newBuilder()
            .setText("Hello, World!")
            .build();

      // Build the voice request, select the language code ("en-US") and the ssml voice gender
      // ("neutral")
      VoiceSelectionParams voice = VoiceSelectionParams.newBuilder()
          .setLanguageCode("en-US")
          .setSsmlGender(SsmlVoiceGender.NEUTRAL)
          .build();

      // Select the type of audio file you want returned
      AudioConfig audioConfig = AudioConfig.newBuilder()
          .setAudioEncoding(AudioEncoding.MP3)
          .build();

      // Perform the text-to-speech request on the text input with the selected voice parameters and
      // audio file type
      SynthesizeSpeechResponse response = textToSpeechClient.synthesizeSpeech(input, voice,
          audioConfig);

      // Get the audio contents from the response
      ByteString audioContents = response.getAudioContent();

      // Write the response to the output file.
      try (OutputStream out = new FileOutputStream("output.mp3")) {
        out.write(audioContents.toByteArray());
        System.out.println("Audio content written to file \"output.mp3\"");
      }
    }
  }
}

您可以将音频内容转换为输入流，然后使用javazoom Player播放

    import javazoom.jl.decoder.JavaLayerException;
    import javazoom.jl.player.Player;

    SynthesizeSpeechResponse response = textToSpeechClient.synthesizeSpeech(input, voice,audioConfig);
    InputStream targetStream = new ByteArrayInputStream(response.getAudioContent().toByteArray());
    Player playMP3;
    playMP3 = new Player(targetStream);
    playMP3.play();
