是否可以取消对 speakTextAsync 的调用？

如何解决是否可以取消对 speakTextAsync 的调用？

我正在使用 javascript SDK of Microsoft Speech Synthesizer 并调用 speakTextAsync 将文本转换为语音。

这很好用，但有时文本很长，我希望能够在中间取消，但我找不到任何方法来做到这一点。该文档似乎没有表明任何取消方式。名称 speakTextAsync 表明它返回一个可以取消的任务，但实际上该方法返回 undefined，我找不到任何其他方法来执行此操作。这怎么办？

解决方法

它说话的时候似乎没有办法阻止它。但实际上，作为一种解决方法，您可以只下载音频文件并自己播放文件，以便您可以控制一切。试试下面的代码：

import com.microsoft.cognitiveservices.speech.*;
import com.microsoft.cognitiveservices.speech.audio.AudioConfig;

import java.nio.file.*;
import java.io.*;
import javax.sound.sampled.*;

public class TextToSpeech {

    public static void main(String[] args) {
        try {

            String speechSubscriptionKey = "key";

            String serviceRegion = "location";

            String audioTempPath = "d://test.wav"; //temp file location

            SpeechConfig config = SpeechConfig.fromSubscription(speechSubscriptionKey,serviceRegion);

          
            AudioConfig streamConfig = AudioConfig.fromWavFileOutput(audioTempPath);

            SpeechSynthesizer synth = new SpeechSynthesizer(config,streamConfig);

            String filePath = "....//test2.txt"; // .txt file for test with long text
            Path path = Paths.get(filePath);
            String text = Files.readString(path);
            synth.SpeakText(text);

            Thread thread = new Thread(new Speaker(audioTempPath));
            thread.start();

            System.out.println("play audio for 8s...");
            Thread.sleep(8000);
            System.out.println("stop play audio");
            thread.stop();

        } catch (Exception ex) {
            System.out.println("Unexpected exception: " + ex);

            assert (false);
            System.exit(1);
        }
    }

}

class Speaker implements Runnable {

    private String path;

    public String getText(String path) {
        return this.path;
    }

    public Speaker(String path) {

        this.path = path;
    }

    public void run() {
        try {
            File file = new File(path);
            AudioInputStream stream;
            AudioFormat format;
            DataLine.Info info;
            Clip clip;

            stream = AudioSystem.getAudioInputStream(file);
            format = stream.getFormat();
            info = new DataLine.Info(Clip.class,format);
            clip = (Clip) AudioSystem.getLine(info);
            clip.open(stream);
            clip.start();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }

}
