You can download the project here

You can use this application by connecting to your GooglePlay account and installing in your mobile one of the many apk management utilities.

The application should look like the image below. But if your mobile has access rights to the Internet instead of the "Voice recognizer not present" assigned to the button, which is obviously inactive you should get the message "Speak" and you should be able to press the button.

MainActivity Examples

//Method to Toast the message
void showToastMessage(String message){
Toast.makeText(this, message, Toast.LENGTH_SHORT).show();

public void checkVoiceRecognition() {
// Checks if  Voice recognition is available
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() == 0) {
mbtSpeak.setText("Voice recognizer not present");
Toast.makeText(this, "Voice recognizer not present",

public void speak(View view) {
 Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
// Specifies the calling package to identify your application.
 intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass()

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//If Voice recognition is successful then it returns RESULT_OK
if(resultCode == RESULT_OK) {

ArrayList<String> textMatchList = data

if (!textMatchList.isEmpty()) {
// If first match contains the "search" word
// Then start a web search
if (textMatchList.get(0).contains("search")) {

String searchQuery = textMatchList.get(0);
searchQuery = searchQuery.replace("search","");
Intent search = new Intent(Intent.ACTION_WEB_SEARCH);
search.putExtra(SearchManager.QUERY, searchQuery);
} else {
// populate the Matches
.setAdapter(new ArrayAdapter<String>(this,
