I'm trying to include a microphone button where user can click it and it can prompt a voice input from the user. Then the voice input will be converted into String and shown in a TextView in my android app. For now, the voice input can be prompted but the converted String will not be shown in my TextView and there are no crashes or logcat. Just that it wont be shown in my TextView. All this is happening in a class which extends Fragment.
Below is the code for my microphone button :-
//Button to activate voice recognition
microphonebutton = (ImageButton) view.findViewById(R.id.button_microphone);
microphonebutton.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, Locale.getDefault());
if (intent.resolveActivity(getActivity().getPackageManager()) != null) {
startActivityForResult(intent, 10);
} else {
Toast.makeText(getActivity().getApplicationContext(), "Your device does not support speech input !",Toast.LENGTH_SHORT).show();
}
}
});
The method onActivityResult:-
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (resultCode) {
case 10:
if (resultCode == Activity.RESULT_OK && data != null) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
texttotranslate.setText("");
texttotranslate.setText(result.get(0), TextView.BufferType.EDITABLE);
}
break;
}
}
I got these codes from a tutorial on youtube and it seemed to be working fine for the person who was presenting the tutorial.
You have a typo in the method onActivityResult. In the switch you are chechking the resultCode twice. First you should check the requestCode. The requestCode is the code which you defined in startActivityForResult, in your case 10.

What is the code about:
With my code I can open a mic, speak into it and see the output.
Present Situation
Right now if I speak into the mic, I see the output and jump directly in other activity.
Requirement
I want take the output in the activity but before I text to much I show you the code.
Mainactivity.java
private TextView voiceInput;
private ImageView speakButton;
private final int REQ_CODE_SPEECH_INPUT = 100;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
voiceInput = (TextView) findViewById(R.id.voiceInput);
speakButton = (ImageView) findViewById(R.id.btnSpeak);
speakButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
askSpeechInput();
}
});
}
// Showing google speech input dialog
private void askSpeechInput() {
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, "Sprechen Sie was ein");
//tent.putStringArrayListExtra("result",resultat);
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
}
}
#Override
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) {
Intent intent=new Intent(this,Zweites.class);
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
voiceInput.setText(result.get(0));
intent.putStringArrayListExtra("resultat",result);
//ActivityZweites wird gestartet
startActivity(intent);
}
break;
}
} }} <br>
In that I got the following problem:
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
//Ausgabe in andere Activity
voiceInput.setText(result.get(0));
Intent intent=new Intent(this,Zweites.class);
intent.putStringArrayListExtra("resultat",result);
//ActivityZweites wird gestartet
startActivity(intent);
}
break;
}
There it outputs the spoken input:
voiceInput.setText(result.get(0));
And afterwards it jumps into the activity.
How can I get this output in the activity without first display the output and jump in another activity?
I tried some things but don´t come to a solution how to fix this problem.
Do you guys got some ideas?
Kind regards
If you simply want to pass the same text to your intent that you're displaying in your TextView, exchange
intent.putStringArrayListExtra("resultat",result);
with
intent.putExtra("resultat", result.get(0));
Then, in your Zweites activity, you can get the string like so:
Intent intent = getIntent();
String text = intent.getStringExtra("resultat");
I am trying to hide the speech recogniser dialog that shows up saying "speak now" and written google as the title ,whenever i call it for passing some voice command. I don't want it to show up. Instead I want it to work in teh background so that the user cannot see it. What should be the correct way to do it?
public void getSpeechInput(View view) {
getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
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 {
Toast.makeText(this, "Your Device Don't Support Speech Input", Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, 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);
txvResult.setText(result.get(0));
String str = txvResult.getText().toString();
if(str.equals("lights on")){
Toast.makeText(MainActivity.this,
"matched", Toast.LENGTH_LONG).show();
count[0]=1;
turnOnFlash();
}
else if(str.equals("lights off")){
Toast.makeText(MainActivity.this,
"didnt", Toast.LENGTH_LONG).show();
count[0]=0;
turnOffFlash();
}
}
break;
}
}
I tried using this but it didn't work:-
getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
Try this. This listener catches the events and you can process them accordingly.
SpeechRecognizer recognizer = SpeechRecognizer.createSpeechRecognizer(this);
recognizer.setRecognitionListener(new RecognitionListener()
{
//Do whatever you want
});
I'm trying to develop game that using voice command to access main menu. I want to ask how to hide tap to speak interface from google speech? Because it almost cover all my screen.
Call promptSpeechInput() to start the speech recognition activity.
Catch the results with onActivityResult(),
/**
* Showing google speech input dialog
* */
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));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
/**
* Receiving speech input
* */
#Override
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) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
For example, from a button:
speechRecButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
promptSpeechInput();
}
});

I'm making new App and i need to use voice recognition to write the words that the user said and do some algorithmic on them, What API's shall i use or a library ?
Thanks
Following two method is enough for basic understanding of Speech to text conversion:
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));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
/**
* Receiving speech input
* */
#Override
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) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
I can share a complete project which is available online as well.

I have an edittext for which I am using speech to text. I would like to append text in the edittext instead of overwriting. How can I achieve that. Right now it captures a sentence and displays in edittext. Thanks
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);
et_text.setText("");
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),"Opps! Your device doesn't support Speech to Text", Toast.LENGTH_SHORT).show();
}
}
#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);
et_text.setText(text.get(0));
}
break;
}
}
}
You can simply use append method instead of setText:
et_text.append(text.get(0));
I guess when you use your code for the first time ,the EditText is empty,then your code executes and set some text after recognizing some speech,on second run you again want to show the text from the speech and want it to be appended to the last text which was set on the EditText.Before setting text on the EditText using setText(),first call getText() on the EditText,and save it in some String variable.Then concatenate the text generated during second run of the code.
if(et_text.getText.length()>0)
{
et_text.setText( et_text.getText().toString() + text.get(0));
}
else
{
et_text.setText(text.get(0));
}
}
