尝试使用Java SDK将来自麦克风的连续音频流直接发送到IBM Watson SpeechToText Web服务.distribution(RecognizeUsingWebSocketsExample)提供的示例之一显示了如何将.WAV格式的文件流式传输到服务.但是,.WAV文件要求提前指定它们的长度,因此一次只将一个缓冲区附加到文件的简单方法是不可行的.

它似乎SpeechToText.recognizeUsingWebSocket可以采取一个流,但喂它一个实例AudioInputStream似乎并没有这样做似乎连接已建立但即使没有返回成绩单RecognizeOptions.interimResults(true).

public class RecognizeUsingWebSocketsExample {
private static CountDownLatch lock = new CountDownLatch(1);

public static void main(String[] args) throws FileNotFoundException, InterruptedException {
SpeechToText service = new SpeechToText();
service.setUsernameAndPassword("<username>", "<password>");

AudioInputStream audio = null;

try {
    final AudioFormat format = new AudioFormat(16000, 16, 1, true, false);
    DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
    TargetDataLine line;
    line = (TargetDataLine)AudioSystem.getLine(info);
    line.open(format);
    line.start();
    audio = new AudioInputStream(line);
    } catch (LineUnavailableException e) {
        // …
