Membuat Aplikasi Pengenalan Suara Indonesia pada Android (Voice Recognition) dengan Speech To Text Bahasa Indonesian

Beberapa saat yang lalu sudah dipelajari Membuat Aplikasi Speech to Teks Inggris di Android, kemudian bagaimana dengan bahasa kebanggaan kita Bahasa Indonesia, apa juga bisa dikenali Android? Eh ternyata bisa juga. Ternyata Google juga sudah mensupport bahasa Indonesia agar bisa dikenali oleh Aplikasi SpeechToText atau Aplikasi Voice Recognition di Android dengan syarat setting Language pada Android sebaiknya diset Bahasa Indonesia juga.

Nah kita mulai membuat Pengenalan Suara Bahsa Indonesia atau Bahasa Indonesian Speech Recognition, pada project Android buat kode program di MainActivity.java seperti ini :




package com.amijaya.speechtotextindonesia;

import java.util.ArrayList;

import android.os.Bundle;
import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.speech.RecognizerIntent;
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 {
// http://cariprogram.blogspot.com
// nuramijaya@gmail.com
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        Button button1 = (Button)findViewById(R.id.button1);
        button1.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "id-ID");

try {
startActivityForResult(intent, 1);

EditText editText1 = (EditText)findViewById(R.id.editText1);
editText1.setText("");
} catch (ActivityNotFoundException a) {
Toast t = Toast.makeText(getApplicationContext(),
"Perangkat Tidak Mendukung",
Toast.LENGTH_SHORT);
t.show();
}

}
});
    }
    
    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

switch (requestCode) {
case 1: {
if (resultCode == RESULT_OK && null != data) {

ArrayList<String> text = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

EditText editText1 = (EditText)findViewById(R.id.editText1);
editText1.setText(text.get(0));
}
break;
}

}
}


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
    
    /*
// CARA MENGECEK APAKAH TTS DISUPPORT DAN MEMANGGIL INSTALLER TTS GOOGLE PLAY
 
   //find out whether speech recognition is supported
        PackageManager packManager = getPackageManager();
        List<ResolveInfo> intActivities = packManager.queryIntentActivities
        (new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
        if (intActivities.size() != 0) {
        //speech recognition is supported - detect user button clicks
            speechBtn.setOnClickListener(this);
            //prepare the TTS to repeat chosen words
            Intent checkTTSIntent = new Intent();  
            //check TTS data  
            checkTTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);  
            //start the checking Intent - will retrieve result in onActivityResult
            startActivityForResult(checkTTSIntent, MY_DATA_CHECK_CODE); 
        }
        else 
        {
        //speech recognition not supported, disable button and output message
            speechBtn.setEnabled(false);
            Toast.makeText(this, "Oops - Speech recognition not supported!", Toast.LENGTH_LONG).show();
        }
        
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    //check speech recognition result 
        if (requestCode == VR_REQUEST && resultCode == RESULT_OK) 
        {
        //store the returned word list as an ArrayList
            ArrayList<String> suggestedWords = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            //set the retrieved list to display in the ListView using an ArrayAdapter
            wordList.setAdapter(new ArrayAdapter<String> (this, R.layout.word, suggestedWords));
        }
        
        //returned from TTS data check
        if (requestCode == MY_DATA_CHECK_CODE) 
        {  
       //we have the data - create a TTS instance
       if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)  
        repeatTTS = new TextToSpeech(this, this);  
       //data not installed, prompt the user to install it  
       else 
       {  
        //intent will take user to TTS download page in Google Play
        Intent installTTSIntent = new Intent();  
        installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);  
        startActivity(installTTSIntent);  
       }  
        }

        //call superclass method
        super.onActivityResult(requestCode, resultCode, data);
    }

*/
    
}

Kemudian layout activity_main.xml seperti ini :


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Speech To Text Indonesia" />

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Bicara" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10" >

        <requestFocus />
    </EditText>

</LinearLayout>


AndroidManifest tidak perlu kita ubah :


<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.amijaya.speechtotextindonesia"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.amijaya.speechtotextindonesia.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>


Hasilnya, Setelah diklik Tombol Bicara kemudian akan muncul Dialog Bicara :

Kemudian suara akan diproses :

Dan dituliskan hasil pengenalan suaranya pada EditText :

Sekali lagi agar aplikasi ini bekerja mengenali Bahasa Indonesia jangan lupa terlebih dahulu buka Setting dan Ubah Bahasa menjadi Bahasa Indonesia.

Project selengkapnya silakan didownload. Jika tidak bisa mungkin bisa membaca caranya ini.

Cobalah dengan bahasa Indonesia yang Baik dan Benar ^_^
