ibm-watson-cognitive 在Java中使用WebSocket识别音频文件

示例

使用 Java-SDK 3.0.1

CountDownLatch lock = new CountDownLatch(1);

SpeechToText service = new SpeechToText();
service.setUsernameAndPassword("<username>", "<password>");

FileInputStream audio = new FileInputStream("filename.wav");

RecognizeOptions options = new RecognizeOptions.Builder()
    .continuous(true)
    .interimResults(true)
    .contentType(HttpMediaType.AUDIO_WAV)
    .build();

service.recognizeUsingWebSocket(audio, options, new BaseRecognizeCallback() {
  @Override
  public void onTranscription(SpeechResults speechResults) {
    System.out.println(speechResults);
    if (speechResults.isFinal())
      lock.countDown();
  }
});

lock.await(1, TimeUnit.MINUTES);
