i want to develop a application to navigate one page to another page using voice command

here is my code

 public class mainActivity extends Activity implements OnClickListener {

 ArrayList<String> StoredCommand = new ArrayList<String>();

private static final String TAG = "VoiceRecognition";

    }
}

according to the stored command i need to navigate those pages.but result is Google voice option work but commands are not working.is there any wrong of my pattern matching...please give me solution for that. thank you

Try this out as a minimal implementation of onActivityResult():

if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK)
{
    ArrayList<String> matches = data.getStringArrayListExtra(
            RecognizerIntent.EXTRA_RESULTS);
    mList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
               matches));
    for (String bestMatch:matches)
    {
        if (bestMatch.equalsIgnoreCase("Path Recoder"))
        {
            Intent myIntent = new Intent(View, PahtRecoder.class);
            startActivityForResult(myIntent, 0);
        }
        else if(bestMatch.equalsIgnoreCase("Path Selector"))
        {
            Intent myIntent = new Intent(View, Pahtselector.class);
            startActivityForResult(myIntent, 0);
        }
        else if(bestMatch.equalsIgnoreCase("Stop"))
        {
            Intent myIntent = new Intent(View, Pahtselector.class);
            startActivityForResult(myIntent, 0);
        }
        else if(bestMatch.equalsIgnoreCase("Pause"))
        {
            Intent myIntent = new Intent(View, Pahtselector.class);
            startActivityForResult(myIntent, 0);
        }
        else
        {
            Log.i(TAG, "COMMAND_NOT_MATCHING");
        }
    }
}

Further Update: My initial post was wrong - StoredCommand should not be used; on older speech recognition platforms they would be provided with a list of possible utterances and the engine would try to match what you say against the possibilities. However, the default engine on Android does not need this. By the way, what does your mList display?

Note also that I have not tested any of the code above...

  • when user says "path recoder" then it should be navigate to the path recoder page.that is what i want.i sored command in array list called StoredCommand.if you say so then tell me what should i do.can you edit this or give me solution.thank you – Kavindi Wicramasingha Jun 13 '12 at 07:46
  • I've updated my answer, so please note `StoredCommand` is never used by the engine; the default Google Voice does not use input hints. – Ken Y-N Jun 13 '12 at 23:51
  • but using Google voice its hard to identify what we said.if we say "Stop" it's not generate stop word in list view.So cannot navigate to the page.so how i get correct word to the list view. – Kavindi Wicramasingha Jun 14 '12 at 02:14
  • @KavindiWicramasingha That is a very good question! It would be nice if there was that more constrained mode available. [Pocket Sphinx](http://cmusphinx.sourceforge.net/2011/05/building-pocketsphinx-on-android/) seems to be one option - here's a [similar question from two years ago](http://stackoverflow.com/questions/4396046/android-speech-recognition-without-using-google-server), so you could perhaps ask again to see if the state of the art has improved - [this non-answer](http://stackoverflow.com/a/4396104/1270789) is what you are after, I think? – Ken Y-N Jun 14 '12 at 02:34
  • Sorry, another comment - here's [a promising question and answer from this April](http://stackoverflow.com/questions/10307373/android-offline-voice-recognition-with-simple-commands-vocabulary). – Ken Y-N Jun 14 '12 at 02:43
  • no its not working.when i say start the exception occure.i think my intent command is not work.it recognize the word but cannot navigate to the page.i think we should change the patten.My list display similar word i spoke.not the correct word but similar. – Kavindi Wicramasingha Jun 14 '12 at 07:55
  • please any idea when i say stop it generate exception.thats mean my intent is wrong – Kavindi Wicramasingha Jun 14 '12 at 14:51

Hi all this is the code for navigate from one page to another page using voice command.It will useful any one
