I want to build an Android application which recognizes speech and converts it to Pronunciation text (i.e to compare true Pronunciation or accent between special word and user speech). I just know it's possible to create speech to text. I want to convert any words that user say.
Is there any API to do it? If not, please help me how to implement it.
I just give a code for speech to text . It Is a demo. I don't know this will help you. But i am using this for my application. Try To use it.
SpeechtoText.java
public class SpeechtoText extends Activity {
protected static final int RESULT_SPEECH = 1;
private ImageButton btnSpeak;
private TextView txtText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtText = (TextView) findViewById(R.id.txtText);
btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
btnSpeak.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
try {
startActivityForResult(intent, RESULT_SPEECH);
txtText.setText("");
} catch (ActivityNotFoundException a) {
Toast t = Toast.makeText(getApplicationContext(),
"Ops! Your device doesn't support Speech to Text",
Toast.LENGTH_SHORT);
t.show();
}
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, 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;
}
}
}
}
activity_main.xml

These libraries might work for you. I personally have not used them in Android, but they are packages for Java.

Android has a native way to provide developers speech recognition using the SpeechRecognizer class.
This answer has a very good explanation of the pros and cons of using this API:
