Android studio, wait for one line of code to complete before starting next

Beginner question...
I have the following 4 lines of code.
The third line asks the user (with speech) whether he / she is certain about an action.
Then the fourth line calls a method called speechYesNo (included below) to listen for the users response.
The problem is that the speechYesNo method is called before the txtSpeech.speak line (3rd line) is finished speaking and it records the "Are you sure... " speech line as well as the users response.
For example, if the user responds "Yes", the result from the speechYesNo method will be something like... "Are you sure you would like to add xxxxx Yes".
I just want the result to be "yes".
Is there a way to force the third line (txtSpeech.speak) to finish before the speechYesNo() method is called?
Thanks
String strCommonName = myUtil.getCommonName(strFinalResult);
String strToSpeak = "Are you sure you would like to add " + strCommonName;
txtSpeech.speak(strToSpeak, TextToSpeech.QUEUE_FLUSH, null);
speechYesNo();
Here is the speechYesNo() method
public void speechYesNo() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
if(intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, 9);
} else {
Toast.makeText(context, "Your device does not support Speech Input.", Toast.LENGTH_LONG).show();
}
}
Here is the onActivityResult...
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 10:
if(resultCode == RESULT_OK && data != null) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String strResult = result.get(0);
Double dblStringComparison = 0.000;
String strFinalResult = "Unknown";
for(int intCount = 0; intCount <= arrAnimals.size()-1; intCount++) {
String strVal1 = strResult;
String strVal2 = myUtil.getCommonName(arrAnimals.get(intCount));
Double dblTemp = myUtil.similarity(strVal1, strVal2 );
if(dblTemp > dblStringComparison){
dblStringComparison = dblTemp;
strFinalResult = arrAnimals.get(intCount);
}
}
atvAnimalName.setText(strFinalResult);
String strCommonName = myUtil.getCommonName(strFinalResult);
String strToSpeak = "Are you sure you would like to add " + strCommonName;
txtSpeech.speak(strToSpeak, TextToSpeech.QUEUE_FLUSH, null);
speechYesNo();
}
break;
case 9:
if(resultCode == RESULT_OK && data != null) {
ArrayList<String> result2 = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String strYesNo0 = result2.get(0);
Toast.makeText(context, strYesNo0, Toast.LENGTH_LONG).show();
}
break;
}
}
Here is the full script
The openSpeechMode method will fire when user clicks an image and will record the users speech selection.
Once this is done I want the app to ask the user is he / she is sure about his / her selection.
If the user responds "yes" then I will do some more work.
The problem as per above is the the speech recorder is recording the "are you sure " question as well as the "yes" response.
public void openSpeechMode(View view) {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
if(intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, 10);
} else {

if(intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, 9);
} else {
Toast.makeText(context, "Your device does not support Speech Input.", Toast.LENGTH_LONG).show();
}
}
#Override

String strResult = result.get(0);
Double dblStringComparison = 0.000;
String strFinalResult = "Unknown";
for(int intCount = 0; intCount <= arrAnimals.size()-1; intCount++) {
String strVal1 = strResult;
String strVal2 = myUtil.getCommonName(arrAnimals.get(intCount));
Double dblTemp = myUtil.similarity(strVal1, strVal2 );
if(dblTemp > dblStringComparison){
dblStringComparison = dblTemp;
strFinalResult = arrAnimals.get(intCount);
}
}
atvAnimalName.setText(strFinalResult);
String strCommonName = myUtil.getCommonName(strFinalResult);
String strToSpeak = "Are you sure you would like to add " + strCommonName;
txtSpeech.speak(strToSpeak, TextToSpeech.QUEUE_FLUSH, null);
// speechYesNo();
}
break;
case 9:
if(resultCode == RESULT_OK && data != null) {

}

Question
The problem is that the speechYesNo method is called before the
txtSpeech.speak
Solution
txtSpeech seems to be TextToSpeech class. thus, you should use UtteranceProgressListener for resolving your problem.
Try as below code.
txtSpeech.setOnUtteranceProgressListener(new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
}
#Override
public void onDone(String utteranceId) {
speechYesNo();
}
#Override
public void onError(String utteranceId) {
}
});
txtSpeech.speak(strToSpeak, TextToSpeech.QUEUE_FLUSH, null);

How to get past information while converting speech to text in android?

As i am developing an android app and wants to convert speech into text, i am using built-in Google speech input activity to convert voice into text. I need past information but it continuously get cleared i got only current response. How need to handle same as google voice keyboard. As i talk it included to current String instep of clear.
MainActivity .java
public class MainActivity extends AppCompatActivity

private EditText txtSpeechInput;
private ImageButton btnSpeak;
private final int REQ_CODE_SPEECH_INPUT = 100;
#Override

{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtSpeechInput = findViewById(R.id.txtSpeechInput);
btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
btnSpeak.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
promptSpeechInput();
}
});
private void promptSpeechInput()
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

{
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
}
catch (ActivityNotFoundException a)
{
Toast.makeText(getApplicationContext(),

Toast.LENGTH_SHORT).show();
}
}

{
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode)
{
case REQ_CODE_SPEECH_INPUT:
{
if (resultCode == RESULT_OK && null != data)
{
final ArrayList<String> result= data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
}
break;
}
}
}

If you only want to save one previously detected String, for this to achieve, you need to make a global String variable and store the value in that variable from results list.(Save the same String as you are setting on text view). But if you want to save all the strings, you need to make global String Arraylist and add all those string in that array list. Below is the code for that.
private EditText txtSpeechInput;
private ImageButton btnSpeak;
private final int REQ_CODE_SPEECH_INPUT = 100;
private List<String> previousStringList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
previousStringList = new ArrayList<>();
txtSpeechInput = findViewById(R.id.txtSpeechInput);
btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
btnSpeak.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
promptSpeechInput();
}
});
}
private void promptSpeechInput() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
getString(R.string.speech_prompt));
intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 20000000);
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
final ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
if (result.get(0) != null) {
previousStringList.add(result.get(0));
}
}
break;
}
}
}
Hope that helps you.If you don't understand anything feel free to ask. If you don't want to save same String twice(already saved string), just replace below conditional line of code..
if (result.get(0) != null && !previousStringList.contains(result.get(0))) {
previousStringList.add(result.get(0));
}

The words get stored in Arraylists.
You can see an example of the implementation here, it works fine. The app stores the words, and then also performs the action requested.

Android Offline Speech Recognition to Display Only Word

I need help with android speech-text. Is it possible to display only the first word that was detected?like when the user inputs "the cat is playing" then the text that will only appear on the text box is the word "the".
The code that I used:
protected static final int RESULT_SPEECH = 1;
private Button btn_mic;
private TextView txtText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.basic_level1);
txtText = (TextView) findViewById(R.id.txt);
btn_mic = (Button) findViewById(R.id.mic);
btn_mic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
try {
startActivityForResult(intent, RESULT_SPEECH);
txtText.setText("");
} catch (ActivityNotFoundException a) {
Toast t = Toast.makeText(getApplicationContext(),
"Opps! Your device doesn't support Speech to Text",
Toast.LENGTH_SHORT);
t.show();
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_SPEECH: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> text = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtText.setText(text.get(0));
}
break;
}
}
}
}
thanks in advance. :)

ArrayList<String> text = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if(text.size()>0){
String firstOne=text.get(0);
if(firstOne.contains(" ")){
String firstWord=firstOne.substring(0, firstOne.indexOf(' '));
txtText.setText(text.get(0));
}else{
txtText.setText(text.get(0));
}
}

startActivityForResult doesnt return to onActivityResult in android

The first time I call startActivityForResult() with requestCode x it return to onActivityResult().But the second time I call startActivityForResult() within the same activity with diffrent requestCode it doesnt return to the onActivityResult() and just proceed
with the code.
I have tried to add this property to the manifest andter the activity
android:noHistory
Why it doesnt return to onActivityResult()?And how i can fix it?
Thanks a lot,

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...

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