Getting Started…
Step 1:
Hello everyone, welcome to another tutorial. Today, we’re going to create a simple text-to-speech app in Android Studio using Java. Let’s get started by setting up a new project.
Step 2:
In this step, we’ll design the layout of our app. We’ll have a TextView to prompt the user, an EditText for input, and a Button to trigger the text-to-speech functionality.
<TextView
android:id="@+id/inputText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Enter text to speak:"
android:textSize="18sp"
android:layout_marginBottom="16dp"/>
<EditText
android:id="@+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/inputText"
android:hint="Type here"
android:inputType="textMultiLine"
android:minLines="3"
android:gravity="start|top"
android:scrollbars="vertical"/>
<Button
android:id="@+id/speakButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/editText"
android:layout_centerHorizontal="true"
android:text="Speak"/>
Step 3:
Now, let’s ensure our app has the necessary permissions for text-to-speech functionality. We’ll add permissions for INTERNET, RECORD_AUDIO, and MODIFY_AUDIO_SETTINGS in the AndroidManifest.xml file.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Step 4:
In this step, we’ll initialize the TextToSpeech object in our MainActivity.java file. This object allows us to convert text to speech in our app.
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import java.util.Locale;
public class MainActivity extends AppCompatActivity {
private TextToSpeech textToSpeech;
private EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = findViewById(R.id.editText);
Button speakButton = findViewById(R.id.speakButton);
textToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(Locale.getDefault());
} else {
Toast.makeText(MainActivity.this, "Initialization failed", Toast.LENGTH_SHORT).show();
}
}
});
speakButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String text = editText.getText().toString();
textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);
}
});
}
@Override
protected void onDestroy() {
if (textToSpeech != null) {
textToSpeech.stop();
textToSpeech.shutdown();
}
super.onDestroy();
}
}
Step 5:
Now, let’s implement the functionality to convert the entered text to speech when the user clicks the button.
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import java.util.Locale;
public class MainActivity extends AppCompatActivity {
private TextToSpeech textToSpeech;
private EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = findViewById(R.id.editText);
Button speakButton = findViewById(R.id.speakButton);
textToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(Locale.getDefault());
} else {
Toast.makeText(MainActivity.this, "Initialization failed", Toast.LENGTH_SHORT).show();
}
}
});
speakButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String text = editText.getText().toString();
if (!text.isEmpty()) {
textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);
} else {
Toast.makeText(MainActivity.this, "Enter text to speak", Toast.LENGTH_SHORT).show();
}
}
});
}
@Override
protected void onDestroy() {
if (textToSpeech != null) {
textToSpeech.stop();
textToSpeech.shutdown();
}
super.onDestroy();
}
}
Step 6:
Lastly, to ensure our app runs smoothly and avoids memory leaks, we release the TextToSpeech resources in the onDestroy() method.
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import java.util.Locale;
public class MainActivity extends AppCompatActivity {
private TextToSpeech textToSpeech;
private EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = findViewById(R.id.editText);
Button speakButton = findViewById(R.id.speakButton);
textToSpeech = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if (status != TextToSpeech.ERROR) {
textToSpeech.setLanguage(Locale.getDefault());
} else {
Toast.makeText(MainActivity.this, "Initialization failed", Toast.LENGTH_SHORT).show();
}
}
});
speakButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String text = editText.getText().toString();
if (!text.isEmpty()) {
textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);
} else {
Toast.makeText(MainActivity.this, "Enter text to speak", Toast.LENGTH_SHORT).show();
}
}
});
}
@Override
protected void onDestroy() {
if (textToSpeech != null) {
textToSpeech.stop();
textToSpeech.shutdown();
}
super.onDestroy();
}
}
Step 7:
That’s it! You’ve successfully created a simple text-to-speech app in Android Studio using Java. Feel free to run the app on an emulator or a physical device to test it out. Let me know if you have any questions or need further assistance!
