Android Bluemix zeigt kein Speaker-Tag

Question

Ich benutze IBM Bluemix, um etwas Audio zu transkribieren, und ich möchte die APIs Sprechererkennung verwenden.

stelle ich die die Erkennungs so zusammen:

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(); 
} 

Aber die zurück JSON umfaßt nicht die Lautsprecher-Tag. Wie kann ich die Lautsprecher-Tag auch mit der Bluemix Java API zurückgegeben bekommen?

Meine Audio-Recorder in Android sieht wie folgt aus:

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(); 
     } 
    } 
}

Basierend auf Ihrem Beispiel schrieb ich eine Beispielanwendung und bekam die Lautsprecher Etiketten zu arbeiten.

Stellen Sie sicher, dass Sie die verwenden. In Ihrem build.gradle hinzufügen

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

Hier ist der Code-Schnipsel, die ein WAV file aus dem assets Ordner erkennt WebSockets, Zwischenergebnisse und Lautsprecher-Label verwenden.

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()); 
    } 
}); 

Wo loadInputStreamFromAssetFile() sind:

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; 
}
