Apa itu Aplikasi Text to Speech?

Bagaimana cara menerapkan class text to speech ini kedalam IDE Android Studio?

1. Buat Project Baru, nama project basing kalian saja
2. Setelah itu masukan kode berikut ini pada activity_main.xml 

   <?xml version="1.0" encoding="utf-8"?><RelativeLayout 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=".MainActivity">
   
   
       <EditText        android:id="@+id/txtSpeech"        android:layout_width="354dp"        android:layout_height="wrap_content"        android:layout_centerInParent="true"        android:hint="Input Text disini!!" />
   
           <Button            android:id="@+id/btnSpeech"            android:layout_marginTop="5dp"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerInParent="true"            android:layout_below="@+id/txtSpeech"            android:text="Bicara"            />
   
   
   </RelativeLayout>

3. Setelah itu buka MainActivity.java nya dan isi dengan source code berikut ini

   package com.blogspot.ilmugratisanbro.texttospeech;
   
   import android.speech.tts.TextToSpeech;
   import android.support.v7.app.AppCompatActivity;
   import android.os.Bundle;
   import android.util.Log;
   import android.view.View;
   import android.widget.Button;
   import android.widget.EditText;
   
   import java.util.Locale;
   
   public class MainActivity extends AppCompatActivity implements        TextToSpeech.OnInitListener {
       private TextToSpeech tts;
       private Button btnBicara;
       private EditText txtText;
   
       @Override    protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
           tts = new TextToSpeech(this, this);
   
           btnBicara = (Button) findViewById(R.id.btnSpeech);
   
           txtText = (EditText) findViewById(R.id.txtSpeech);
   
           // button on click event        btnBicara.setOnClickListener(new View.OnClickListener() {
   
               @Override            public void onClick(View arg0) {
                   speakOut();
               }
   
           });
       }
       public void onDestroy() {
           // Don't forget to shutdown tts!        if (tts != null) {
               tts.stop();
               tts.shutdown();
           }
           super.onDestroy();
       }
       public void onInit(int status) {
   
           if (status == TextToSpeech.SUCCESS) {
   
               int result = tts.setLanguage(Locale.US);
   
               if (result == TextToSpeech.LANG_MISSING_DATA                    || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                   Log.e("TTS", "This Language is not supported");
               } else {
                   btnBicara.setEnabled(true);
                   speakOut();
               }
   
           } else {
               Log.e("TTS", "Initilization Failed!");
           }
   
       }
   
       private void speakOut() {
           String text = txtText.getText().toString();
   
           tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
          // tts.setPitch((float) 0.6);        //tts.setSpeechRate(2);    }
   }

4. Selanjutnya  Kalian Running aplikasinya ke emulator kalian. 
   

1.  Disini saya anggap kalian sudah membuat sebuah project baru
2.  Di bagian activity_layout.xml kalian tambahkan kode script dibawah ini
   

   <?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:weightSum="5"    tools:context="com.wayandev.deteksi.MainActivity">
   
       <SurfaceView        android:id="@+id/surfaceView"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="4" />
       <TextView        android:id="@+id/text_view"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_margin="8dp"        android:layout_weight="1"        android:gravity="center"        android:textStyle="bold"        android:text="@string/txt_message"        android:textColor="@android:color/black"        android:textSize="20sp" />
   
   </LinearLayout>

3. Kemudian pada Grandle  kalian tambahkan library google vision "implementation 'com.google.android.gms:play-services-vision:15.0.1'". perhatikan gambar dibawah ini:
   
   
4. Selanjutnya kita menuju MainActivity.java dan tambahkan script di bawah ini

   package com.wayandev.deteksi;
   
   import android.Manifest;
   import android.content.pm.PackageManager;

       private static final int requestPermissionID = 101;
   
   
       @Override    protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
           mCameraView = findViewById(R.id.surfaceView);
           mTextView = findViewById(R.id.text_view);
   
   
           //inisialisasi text to speech        textToSpeech=new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
               @Override            public void onInit(int status) {
                   if (status == TextToSpeech.SUCCESS) {
   
                       int result = textToSpeech.setLanguage(Locale.US);
   
                       if (result == TextToSpeech.LANG_MISSING_DATA                            || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                           Log.e("TTS", "This Language is not supported");
                       } else {
   
                           speakOut();
                       }
   
                   } else {
                       Log.e("TTS", "Initilization Failed!");
                   }
               }
           });
   
           startCameraSource();
       }
   
       private void speakOut() {
           //Get the text typed        String text = mTextView.getText().toString();
           //If no text is typed, tts will read out 'You haven't typed text'        //else it reads out the text you typed        if (text.length() == 0) {
               textToSpeech.speak("You haven't text", TextToSpeech.QUEUE_FLUSH, null);
           } else {
               textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
           }
   
       }
   
       @Override    public void onDestroy() {
           // Don't forget to shutdown tts!        if (textToSpeech != null) {
               textToSpeech.stop();
               textToSpeech.shutdown();
           }
           super.onDestroy();
       }
       private void startCameraSource() {
           //Create the TextRecognizer        final TextRecognizer textRecognizer = new TextRecognizer.Builder(getApplicationContext()).build();
   
           if (!textRecognizer.isOperational()) {
               Log.w(TAG, "Detector dependencies not loaded yet");
           } else {
   
               //Initialize camerasource to use high resolution and set Autofocus on.            mCameraSource = new CameraSource.Builder(getApplicationContext(), textRecognizer)
                       .setFacing(CameraSource.CAMERA_FACING_BACK)
                       .setRequestedPreviewSize(1280, 1024)
                       .setAutoFocusEnabled(true)
                       .setRequestedFps(2.0f)

                       try {
   
                           if (ActivityCompat.checkSelfPermission(getApplicationContext(),
                                   Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
   
                               ActivityCompat.requestPermissions(MainActivity.this,
                                       new String[]{Manifest.permission.CAMERA},
                                       requestPermissionID);
                               return;
                           }
                           mCameraSource.start(mCameraView.getHolder());
                       } catch (IOException e) {
                           e.printStackTrace();
                       }
                   }

                   /**                 * Detect all the text from camera using TextBlock and the values into a stringBuilder                 * which will then be set to the textView.                 */                @Override                public void receiveDetections(Detector.Detections<TextBlock> detections) {

                                   //dibaca secara berulang jika ada text baru yang di detect                                speakOut();
                               }
                           });
                       }
                   }
               });
           }
       }
   }

5. Setiap kalian Mengcopy Pastekan Script Diatas, kalian perhatikan Package Name Id kalian supaya tidak error.
6. Terakhir Kalian tambahkan Permission Kamera di Manifest kalian.
   
7. Untuk File String nya bisa kalian lihat dibawah ini
