Android Bluemix không hiển thị thẻ loa

Question

Tôi đang sử dụng Bluemix của IBM để phiên âm một số âm thanh và tôi muốn sử dụng nhận dạng loa của API.

tôi thiết lập các bộ nhận dạng như thế này:

private RecognizeOptions getRecognizeOptions() { 
    return new RecognizeOptions.Builder() 
      .continuous(true) 
      .contentType(ContentType.OPUS.toString()) 
      //.model("en-US") 
      .model("en-US_BroadbandModel") 
      .timestamps(true) 
      .smartFormatting(true) 
      .interimResults(true) 
      .speakerLabels(true) 
      .build(); 
} 

Nhưng JSON doesnt trở bao gồm thẻ loa. Làm thế nào tôi có thể nhận được thẻ loa cũng quay trở lại với API java bluemix?

máy ghi âm của tôi trong Android trông như thế này:

private void recordMessage() { 
    //mic.setEnabled(false); 
    speechService = new SpeechToText(); 
    speechService.setUsernameAndPassword("usr", "pwd"); 
    if(listening != true) { 
     capture = new MicrophoneInputStream(true); 
     new Thread(new Runnable() { 
      @Override public void run() { 
       try { 
        speechService.recognizeUsingWebSocket(capture, getRecognizeOptions(), new MicrophoneRecognizeDelegate()); 
       } catch (Exception e) { 
        showError(e); 
       } 
      } 
     }).start(); 
     Log.v("TAG",getRecognizeOptions().toString()); 
     listening = true; 
     Toast.makeText(MainActivity.this,"Listening....Click to Stop", Toast.LENGTH_LONG).show(); 
    } else { 
     try { 
      capture.close(); 
      listening = false; 
      Toast.makeText(MainActivity.this,"Stopped Listening....Click to Start", Toast.LENGTH_LONG).show(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
}

Dựa trên ví dụ của bạn tôi đã viết một ứng dụng mẫu và nhận được các nhãn loa để làm việc.

Đảm bảo bạn đang sử dụng Java-SDK 4.2.1. Trong build.gradle bạn thêm

compile 'com.ibm.watson.developer_cloud:java-sdk:4.2.1' 

Dưới đây là đoạn mã mà công nhận một WAV file từ assets thư mục sử dụng WebSockets, kết quả tạm thời, và nhãn loa.

RecognizeOptions options = new RecognizeOptions.Builder() 
    .contentType("audio/wav") 
    .model(SpeechModel.EN_US_NARROWBANDMODEL.getName()) 
    .interimResults(true) 
    .speakerLabels(true) 
    .build(); 

SpeechToText service = new SpeechToText(); 
service.setUsernameAndPassword("SPEECH-TO-TEXT-USERNAME", "SPEECH-TO-TEXT-PASSWORD"); 

InputStream audio = loadInputStreamFromAssetFile("speaker_label.wav"); 

service.recognizeUsingWebSocket(audio, options, new BaseRecognizeCallback() { 
    @Override 
    public void onTranscription(SpeechResults speechResults) { 
     Assert.assertNotNull(speechResults); 
     System.out.println(speechResults.getResults().get(0).getAlternatives().get(0).getTranscript()); 
     System.out.println(speechResults.getSpeakerLabels()); 
    } 
}); 

đâu loadInputStreamFromAssetFile() là:

public static InputStream loadInputStreamFromAssetFile(String fileName){ 
    AssetManager assetManager = getAssets(); // From Context 
    try { 
    InputStream is = assetManager.open(fileName); 
    return is; 
    } catch (IOException e) { 
    e.printStackTrace(); 
    } 
    return null; 
}
