Create Text To Speech Conversion Android Application Using Android Studio

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

• Android Studio version 2.3.3
• Little bit XML and JAVA knowledge.
• Android Emulator (or) Android mobile
• Download link (Android Studio)

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.

 

 

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.

 

 

Now, select the version of Android and select the target Android devices.

 

 

Step 3

 

Now, add the activity and click the "Next" button.

 

 

Add Activity name and click "Finish".

 

 

Step 4

 

Go to activity_main.xml, This XML file contains the designing code for an Android app in the activity_main.xml;

 

 

The XML code given below.

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    tools:context="abu.text_to_speech.MainActivity" >
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="70dp"
        android:ems="10"
        android:inputType="textPersonName" />
        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignRight="@+id/editText1"
            android:layout_below="@+id/editText1"
            android:layout_marginRight="49dp"
            android:layout_marginTop="101dp"
            android:text="Button" />
    </RelativeLayout>
</android.support.constraint.ConstraintLayout>

Step 5

 

Go to  Main Activity.java, This Java program is the backend language for an Android.

 

 

The java code is given below

package abu.text_to_speech;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity implements OnInitListener {
    EditText ee;
    Button b1;
    TextToSpeech tts;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ee=(EditText)findViewById(R.id.editText1);
        b1=(Button)findViewById(R.id.button1);
        b1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                String str=ee.getText().toString();
                tts.speak(str,TextToSpeech.QUEUE_FLUSH,null);
            }
        });
        Intent i =new Intent();
        i.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
        startActivityForResult(i, 1);
    }
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        if(requestCode==1)
        {
            if(resultCode==TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)
            {
                tts= new TextToSpeech(this,this);
            }
            else
            {
                Intent i=new Intent();
                i.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                startActivity(i);
            }
        }
    }

    @Override
    public void onInit(int status) {
        // TODO Auto-generated method stub
        if(status==TextToSpeech.SUCCESS)
        {
            Toast.makeText(getApplicationContext(), "engine installed",1000).show();
        }
        if(status==TextToSpeech.ERROR)
        {
            Toast.makeText(getApplicationContext(), "engine not installed", 1000).show();
        }
    }
}

Step 6

 

Now, go to the menu bar and click make a project or press ctrl+f9 to debug the error.

 

 

Step 7

 

Then click Run button or press shift+f10 To run the project. And choose the virtual machine and click OK.

 

 

Conclusion

 

We have successfully created a text to speech conversion Android application using the Android studio.
