Membuat Aplikasi Speech To Text Voice

Assalamualaiqum ☺

Kali ini masih saya akan memposting materi Android yaitu Speech To Text Voice Recognition Android.

Ok langsung saja berikut langkah – langkahnya:

1. Pertama buat Project Android. Kemudian pada MainActivity kita tuliskan kode program ini :

package com.amijaya.speechtotextinggris;

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, "en-US");

   try {

    startActivityForResult(intent, 1);

    

    EditText editText1 = (EditText)findViewById(R.id.editText1);

    editText1.setText("");

   } catch (ActivityNotFoundException a) {

    Toast t = Toast.makeText(getApplicationContext(),

      "Device Not Supported",

      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);

   }

 */

   

}

2. Kemudian buat layout di file 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 English" />

   <Button

       android:id="@+id/button1"

       android:layout_width="wrap_content"

       android:layout_height="wrap_content"

       android:text="Speak" />

   <EditText

       android:id="@+id/editText1"

       android:layout_width="match_parent"

       android:layout_height="wrap_content"

       android:ems="10" >

       <requestFocus />

   </EditText>

</LinearLayout>

3. Dan terakhir file AndroidManifest.xml tidak perlu kita rubah :
   

<manifest android:versioncode="1" android:versionname="1.0" package="com.amijaya.speechtotextinggris" xmlns:android="http://schemas.android.com/apk/res/android">

   <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:label="@string/app_name" android:name="com.amijaya.speechtotextinggris.MainActivity">

           <intent-filter>

               <action android:name="android.intent.action.MAIN">

               <category android:name="android.intent.category.LAUNCHER">

           </category></action></intent-filter>

       </activity>

   </application>

</uses-sdk></manifest>

Hasilnya, Setelah kita klik Tombol akan muncul dialog Speak Now :

Kemudian akan diproses :

Kemudian setelah suara dikenali akan muncul tulisannya di EditText :

Agar pengenalan Speech To Text bekerja maksimal dalam mengenali kata dalam Bahasa Inggris (English) silakan ubah di Setting dengan Language English (United States) :

Semoga Bermanfaat ☺
