Introduction

Android is one of the most popular operating systems for mobile. In this article, I will show you how to create Text to Speech conversion Android application using Android Studio.
Requirements
Steps should be followed
Follow these steps to create a Text to Speech conversion Android application using Android Studio and I have included the source code below.
Step 1
Open Android Studio and Start a New Android Studio Project.
Android
Step 2
You can choose your application name and choose where your project is stored on the location. If you wish to use C++ for coding the project, mark the "Include C++ support", and click the "Next" button.
Android
Now, select the version of Android and select the target Android devices.
Android
Step 3
Now, add the activity and click the "Next" button.
Android
Add Activity name and click "Finish".
Android
Step 4
Go to activity_main.xml, This XML file contains the designing code for an Android app in the activity_main.xml;
Android
The XML code given below.
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3. xmlns:app="http://schemas.android.com/apk/res-auto"
  4. xmlns:tools="http://schemas.android.com/tools"
  5. android:layout_width="match_parent"
  6. android:layout_height="match_parent"
  8. tools:context="abu.text_to_speech.MainActivity" >
  9. <RelativeLayout
  10. android:layout_width="match_parent"
  11. android:layout_height="wrap_content"
  12. android:orientation="vertical">
  13. <EditText
  14. android:id="@+id/editText1"
  15. android:layout_width="wrap_content"
  16. android:layout_height="wrap_content"
  17. android:layout_marginTop="70dp"
  18. android:ems="10"
  19. android:inputType="textPersonName" />
  20. <Button
  21. android:id="@+id/button1"
  22. android:layout_width="wrap_content"
  23. android:layout_height="wrap_content"
  24. android:layout_alignRight="@+id/editText1"
  25. android:layout_below="@+id/editText1"
  26. android:layout_marginRight="49dp"
  27. android:layout_marginTop="101dp"
  28. android:text="Button" />
  29. </RelativeLayout>
  30. </android.support.constraint.ConstraintLayout>
Step 5
Go to Main Activity.java, This Java program is the backend language for an Android.
Android
The java code is given below
  1. package abu.text_to_speech;
  2. import android.os.Bundle;
  3. import android.app.Activity;
  4. import android.content.Intent;
  5. import android.speech.tts.TextToSpeech;
  6. import android.speech.tts.TextToSpeech.OnInitListener;
  7. import android.view.Menu;
  8. import android.view.View;
  9. import android.view.View.OnClickListener;
  10. import android.widget.Button;
  11. import android.widget.EditText;
  12. import android.widget.Toast;
  13. public class MainActivity extends Activity implements OnInitListener {
  14. EditText ee;
  15. Button b1;
  16. TextToSpeech tts;
  17. @Override
  18. protected void onCreate(Bundle savedInstanceState) {
  19. super.onCreate(savedInstanceState);
  20. setContentView(R.layout.activity_main);
  21. ee=(EditText)findViewById(R.id.editText1);
  22. b1=(Button)findViewById(R.id.button1);
  23. b1.setOnClickListener(new OnClickListener() {
  24. @Override
  25. public void onClick(View v) {
  26. // TODO Auto-generated method stub
  27. String str=ee.getText().toString();
  28. tts.speak(str,TextToSpeech.QUEUE_FLUSH,null);
  29. }
  30. });
  31. Intent i =new Intent();
  32. i.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
  33. startActivityForResult(i, 1);
  34. }
  35. @Override
  36. protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  37. // TODO Auto-generated method stub
  38. super.onActivityResult(requestCode, resultCode, data);
  39. if(requestCode==1)
  40. {
  41. if(resultCode==TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)
  42. {
  43. tts= new TextToSpeech(this,this);
  44. }
  45. else
  46. {
  47. Intent i=new Intent();
  48. i.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
  49. startActivity(i);
  50. }
  51. }
  52. }
  54. @Override
  55. public void onInit(int status) {
  56. // TODO Auto-generated method stub
  57. if(status==TextToSpeech.SUCCESS)
  58. {
  59. Toast.makeText(getApplicationContext(), "engine installed",1000).show();
  60. }
  61. if(status==TextToSpeech.ERROR)
  62. {
  63. Toast.makeText(getApplicationContext(), "engine not installed", 1000).show();
  64. }
  65. }
  66. }
Step 6
Now, go to the menu bar and click make a project or press ctrl+f9 to debug the error.
Android
Step 7
Then click Run button or press shift+f10 To run the project. And choose the virtual machine and click OK.
