Is there a way to use the SpeechRecognizer API directly for speech input?

Here is the code using SpeechRecognizer class (sourced from here and here): import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.speech.RecognitionListener; import android.speech.RecognizerIntent; import android.speech.SpeechRecognizer; import android.widget.Button; import android.widget.TextView; import java.util.ArrayList; import android.util.Log; public class VoiceRecognitionTest extends Activity implements OnClickListener { private TextView mText; private SpeechRecognizer sr; private static final String TAG … Read more
