Popup von Google Speech deaktivieren

Question

Ich möchte das Popup von Google Speech deaktivieren. Ich möchte, dass es im Hintergrund läuft, also sollte kein Popup auftauchen. Ich programmiere in Visual Studio mit C# und ich möchte eine Spracherkennung App auf/in Android machen.

I downloaded the sample code from the Xamarin page

Code:

protected override void OnCreate(Bundle bundle) 
{ 
    base.OnCreate(bundle); 

    // set the isRecording flag to false (not recording) 
    isRecording = false; 

    // Set our view from the "main" layout resource 
    SetContentView(Resource.Layout.Main); 

    // get the resources from the layout 
    recButton = FindViewById<Button>(Resource.Id.btnRecord); 
    textBox = FindViewById<TextView>(Resource.Id.textYourText); 


    // check to see if we can actually record - if we can, assign the event to the button 
    string rec = Android.Content.PM.PackageManager.FeatureMicrophone; 
    if (rec != "android.hardware.microphone") 
    { 
     // no microphone, no recording. Disable the button and output an alert 
     var alert = new AlertDialog.Builder(recButton.Context); 
     alert.SetTitle("You don't seem to have a microphone to record with"); 
     alert.SetPositiveButton("OK", (sender, e) => 
     { 
      textBox.Text = "No microphone present"; 
      recButton.Enabled = false; 
      return; 
     }); 

     alert.Show(); 
    } 
    else 
    { 
     recButton.Click += delegate 
     { 
      // change the text on the button 
      recButton.Text = "End Recording"; 
      isRecording = !isRecording; 
      if (isRecording) 
      { 
       // create the intent and start the activity 
       var voiceIntent = new Intent(RecognizerIntent.ActionRecognizeSpeech); 
       voiceIntent.PutExtra(RecognizerIntent.ExtraLanguageModel, RecognizerIntent.LanguageModelFreeForm); 

       // put a message on the modal dialog 
       voiceIntent.PutExtra(RecognizerIntent.ExtraPrompt, Application.Context.GetString(Resource.String.messageSpeakNow)); 

       // if there is more then 1.5s of silence, consider the speech over 
       voiceIntent.PutExtra(RecognizerIntent.ExtraSpeechInputCompleteSilenceLengthMillis, 1500); 
       voiceIntent.PutExtra(RecognizerIntent.ExtraSpeechInputPossiblyCompleteSilenceLengthMillis, 1500); 
       voiceIntent.PutExtra(RecognizerIntent.ExtraSpeechInputMinimumLengthMillis, 15000); 
       voiceIntent.PutExtra(RecognizerIntent.ExtraMaxResults, 1); 
       voiceIntent.PutExtra(RecognizerIntent.ExtraLanguage, Java.Util.Locale.German); 


       // you can specify other languages recognised here, for example 

       // if you wish it to recognise the default Locale language and German 
       // if you do use another locale, regional dialects may not be recognised very well 

       voiceIntent.PutExtra(RecognizerIntent.ExtraLanguage, Java.Util.Locale.Default); 
       StartActivityForResult(voiceIntent, VOICE); 
      } 
     }; 
    } 
} 

protected override void OnActivityResult(int requestCode, Result resultVal, Intent data) 
{ 
    if (requestCode == VOICE) 
    { 
     if (resultVal == Result.Ok) 
     { 
      var matches = data.GetStringArrayListExtra(RecognizerIntent.ExtraResults); 
      if (matches.Count != 0) 
      { 
       string textInput = textBox.Text + matches[0]; 

       // limit the output to 500 characters 
       if (textInput.Length > 500) 
        textInput = textInput.Substring(0, 500); 
       textBox.Text = textInput; 
      } 
      else 
       textBox.Text = "No speech was recognised"; 
      // change the text back on the button 
      recButton.Text = "Start Recording"; 
     } 
    } 
    base.OnActivityResult(requestCode, resultVal, data); 
} 

Kann mir jemand helfen das Popup zu deaktivieren?

Answer 1

Sie können die SpeechRecognizer für Ihre App implementieren. Die Implementierung dieser API wird wahrscheinlich Audio auf entfernte Server streamen, um eine Spracherkennung durchzuführen.

Ihre App muss die Berechtigung RECORD_AUDIO haben.

Zum Beispiel:

public class MainActivity : Activity, IRecognitionListener 
{ 
    private TextView tv; 
    private SpeechRecognizer sr; 

    protected override void OnCreate(Bundle bundle) 
    { 
     base.OnCreate(bundle); 

     // Set our view from the "main" layout resource 
     SetContentView(Resource.Layout.Main); 

     sr = SpeechRecognizer.CreateSpeechRecognizer(this); 
     sr.SetRecognitionListener(this); 

     Button btn = FindViewById<Button>(Resource.Id.btn); 
     btn.Click += (sender, e) => 
     { 
      Intent intent = new Intent(RecognizerIntent.ActionRecognizeSpeech); 
      intent.PutExtra(RecognizerIntent.ExtraLanguageModel, RecognizerIntent.LanguageModelFreeForm); 
      intent.PutExtra(RecognizerIntent.ExtraCallingPackage, "this package"); 
      intent.PutExtra(RecognizerIntent.ExtraMaxResults, 5); 
      sr.StartListening(intent); 
     }; 

     tv = FindViewById<TextView>(Resource.Id.tv); 
    } 

    public void OnBeginningOfSpeech() 
    { 
     tv.Text = "Beginning"; 
    } 

    public void OnBufferReceived(byte[] buffer) 
    { 
    } 

    public void OnEndOfSpeech() 
    { 
    } 

    public void OnError([GeneratedEnum] SpeechRecognizerError error) 
    { 
     tv.Text = error.ToString(); 
    } 

    public void OnEvent(int eventType, Bundle @params) 
    { 
    } 

    public void OnPartialResults(Bundle partialResults) 
    { 
    } 

    public void OnReadyForSpeech(Bundle @params) 
    { 
     tv.Text = "Ready!"; 
    } 

    public void OnResults(Bundle results) 
    { 
     var data = results.GetStringArrayList(SpeechRecognizer.ResultsRecognition); 
     StringBuilder builder = new StringBuilder(); 
     for (int i = 0; i < data.Count; i++) 
     { 
      builder.Append(data[i]); 
     } 
     tv.Text = builder.ToString(); 
    } 

    public void OnRmsChanged(float rmsdB) 
    { 
    } 
} 

Dieser noch verwendet Googles Sprachdienst, wenn Ihr Gerät/Region diesen Dienst nicht unterstützt, müssen Sie andere Sprachdienste zu finden und ihre API in Ihrer Anwendung verwenden.
