Glass voice command nearest match from given list

The Google GDK doesn’t support this feature yet. However, the necessary features are already available in some libraries and you can use them as long as the GDK doesn’t support this natively.
What you have to do:

1. Pull the GlassVoice.apk from your Glass: adb pull /system/app/GlassVoice.apk

2. Use dex2jar to convert this apk into a jar file.

3. Add the jar file to your build path

Now you can use this library like this:

public class VoiceActivity extends Activity {

    private VoiceInputHelper mVoiceInputHelper;
    private VoiceConfig mVoiceConfig;

        @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.voice_activity);

        String[] items = {"red", "green", "blue", "orange"};
        mVoiceConfig = new VoiceConfig("MyVoiceConfig", items);
        mVoiceInputHelper = new VoiceInputHelper(this, new MyVoiceListener(mVoiceConfig),
                VoiceInputHelper.newUserActivityObserver(this));
    }

    @Override
    protected void onResume() {
        super.onResume();
        mVoiceInputHelper.addVoiceServiceListener();
    }

    @Override
    protected void onPause() {
        super.onPause();
        mVoiceInputHelper.removeVoiceServiceListener();
    }

    public class MyVoiceListener implements VoiceListener {
        protected final VoiceConfig voiceConfig;

        public MyVoiceListener(VoiceConfig voiceConfig) {
            this.voiceConfig = voiceConfig;
        }

        @Override
        public void onVoiceServiceConnected() {
            mVoiceInputHelper.setVoiceConfig(mVoiceConfig, false);
        }

        @Override
        public void onVoiceServiceDisconnected() {

        }

        @Override
        public VoiceConfig onVoiceCommand(VoiceCommand vc) {
            String recognizedStr = vc.getLiteral();
            Log.i("VoiceActivity", "Recognized text: "+recognizedStr);

            return voiceConfig;
        }

        @Override
        public FormattingLogger getLogger() {
            return FormattingLoggers.getContextLogger();
        }

        @Override
        public boolean isRunning() {
            return true;
        }

        @Override
        public boolean onResampledAudioData(byte[] arg0, int arg1, int arg2) {
            return false;
        }

        @Override
        public boolean onVoiceAmplitudeChanged(double arg0) {
            return false;
        }

        @Override
        public void onVoiceConfigChanged(VoiceConfig arg0, boolean arg1) {

        }
    }

}
