How to use voice recognition and auto write the words - android

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.

"Saving audio to .....#gmail.com" toast when using RecognizerIntent.ACTION_RECOGNIZE_SPEECH

I am using the RecognizerIntent.ACTION_RECOGNIZE_SPEECH to capture audio using the following code:
public void promptSpeechInput() {
if (checkAudioPermission()) {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak Your Query Now");
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} else {
showShortSnackBar("Record Permission Required");
}
}
and I have implemented the onActivityResult as follows:
#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);
String userQuery = result.get(0);
addMessage(false, "Query: \n" + userQuery);
txtSpeechInput.setText(userQuery);
}
break;
}
}
}
Everything works fine except I get an annoying toast saying:
"Saving audio to .....#gmail.com"
How can I get rid of this toast message?

Android Voice Recognition without Internet

I am currently trying to create a voice-to-speech application. My phone will be connected to a WiFi that will not be connected to the internet. I am currently using RecognizerIntent, and it will take significantly longer because the WiFi has no internet connection.
Is there a way to use RecognizerIntent that uses the offline language package immediately instead of trying to connect to Google server first?
I am quite new to this, appreciate the help!
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,
"Hi speak something");
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
}
}
// 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);
voiceInput.setText(result.get(0));
}
break;
}
}
}

How do I hide the speechRecogniser activity behind the main activity?

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
});

Hide tap to speak interface google speech api

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();
}
});
