Android speech Recognition App Without Pop Up
提问by Liam Shalon
I'm currently looking into getting a career with JAVA and have decided to start by building an app. I have this code right here that I am using to trigger Speech Recognition.
我目前正在寻找 JAVA 的职业生涯，并决定从构建应用程序开始。我在这里有这个代码，我用它来触发语音识别。
public class MainActivity extends Activity implements OnClickListener{
private static final int VR_REQUEST = 999;
private ListView wordList;
private final String LOG_TAG = "SpeechRepeatActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button speechBtn = (Button) findViewById(R.id.speech_btn);
wordList = (ListView) findViewById (R.id.word_list);
PackageManager packManager= getPackageManager();
List<ResolveInfo> intActivities = packManager.queryIntentActivities
(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (intActivities.size() !=0){
speechBtn.setOnClickListener(this);
} else {
speechBtn.setEnabled(false);
Toast.makeText(this,"Oops - Speech Recognition Not Supported!",
Toast.LENGTH_LONG).show();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void onClick(View v){
if (v.getId() == R.id.speech_btn) {
listenToSpeech();
}
}
private void listenToSpeech() {
//start the speech recognition intent passing required data
Intent listenIntent =
new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
//indicate package
listenIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
getClass().getPackage().getName());
//message to display while listening
listenIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say a word!");
//set speech model
listenIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
//specify number of results to retrieve
listenIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
//start listening
startActivityForResult(listenIntent, VR_REQUEST);
}
@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));
}
//this detects which one the user clicks
wordList.setOnItemClickListener(new OnItemClickListener(){
//click listener for items within list
public void onItemClick(AdapterView<?> parent,
View view, int position, long id){
//cast the
TextView wordView = (TextView)
//retrive the chosen word
String wordChosen= (String) wordView.
//output for debugging
Log.v(LOG_TAG, "chosen:" +wordChosen);
}});
super.onActivityResult(requestCode, resultCode, data);
}
}
In this app the user presses a button and gets displayed with the Google Voice Input screen where you can click a button (it actually goes automatically) and you can speak, it will stop and it will display it. I don't want that window to pop up at all though. Instead just let the user click the button and be able to speak and let the app stop and display the text automatically (it already does that).
在这个应用程序中，用户按下一个按钮并显示在谷歌语音输入屏幕上，你可以点击一个按钮（它实际上是自动运行的），你可以说话，它会停止并显示它。我根本不想弹出那个窗口。而只是让用户单击按钮并能够说话并让应用程序停止并自动显示文本（它已经这样做了）。
PLEASE! I understand that there are already answers on the form showing how to do this, in fact a user name JEEZ posted some code right here.
请！我知道表单上已经有答案显示如何执行此操作，实际上用户名 JEEZ就在此处发布了一些代码。
I don't know if I understood where to put this in my project file. I AM A NOOB! If anyone could help clarify this I would GREATLY appreciate your help.
我不知道我是否理解将它放在我的项目文件中的哪个位置。我是菜鸟！如果有人可以帮助澄清这一点，我将非常感谢您的帮助。

Add the following permission:
添加以下权限：
<uses-permission android:name="android.permission.RECORD_AUDIO" />
class members
班员
private SpeechRecognizer mSpeechRecognizer;
private Intent mSpeechRecognizerIntent;
private boolean mIslistening;
In onCreate
在创建中
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
.........
.........
mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
this.getPackageName());
SpeechRecognitionListener listener = new SpeechRecognitionListener();
mSpeechRecognizer.setRecognitionListener(listener);
}
in your button listener just use this code
在您的按钮侦听器中只需使用此代码
if (!mIsListening)
{
mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
}
In onDestroy
在销毁
if (mSpeechRecognizer != null)
{
mSpeechRecognizer.destroy();
}
Inside your activity create the inner class
在您的活动中创建内部类
protected class SpeechRecognitionListener implements RecognitionListener
{
@Override
public void onBeginningOfSpeech()
{
//Log.d(TAG, "onBeginingOfSpeech");
}
@Override
public void onBufferReceived(byte[] buffer)
{

@Override
public void onEndOfSpeech()
{
//Log.d(TAG, "onEndOfSpeech");
}
@Override
public void onError(int error)
{
mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
//Log.d(TAG, "error = " + error);
}
@Override
public void onEvent(int eventType, Bundle params)
{
}
@Override
public void onPartialResults(Bundle partialResults)
{
}
@Override

It's been a long time since the post. Still for those who are looking, the above code provided by Hoan is almost complete, but there is an important line missing. Both in question and answer and I am not sure how it could work without that.
帖子已经很久了。仍然对于正在寻找的人来说，以上由Hoan提供的代码几乎完整，但缺少重要的一行。无论是问题还是答案，我都不确定如果没有它，它会如何工作。
You need to create the SpeechRecognitionListener and set it as a listener for the SpeechRecognizer. Also it has to be done before we make a call to startListening() method of the SpeechRecognizer.
您需要创建 SpeechRecognitionListener 并将其设置为 SpeechRecognizer 的侦听器。此外，它必须在我们调用 SpeechRecognizer 的 startListening() 方法之前完成。
SpeechRecognitionListener listener = new SpeechRecognitionListener(); mSpeechRecognizer.setRecognitionListener(listener);
SpeechRecognitionListener listener = new SpeechRecognitionListener(); mSpeechRecognizer.setRecognitionListener(listener);
Then you also need to remove the listener from the onError event.
然后您还需要从 onError 事件中删除侦听器。

Don't Forget to add permission of following:-
不要忘记添加以下权限：-
<uses-permission android:name="android.permission.RECORD_AUDIO" />

I ran into that issue as well. It seems like having startActivityForResult(...)will enable the pop-up mic, then you can handle the response in onActivityResult(). However, simply adding that startActivityForResultmessed up my startListening(mSpeechRecognizerIntent), so you may need to do more adjustment.
我也遇到了这个问题。似乎startActivityForResult(...)将启用弹出式麦克风，然后您可以处理onActivityResult(). 但是，简单地添加它会startActivityForResult弄乱我的startListening(mSpeechRecognizerIntent)，因此您可能需要进行更多调整。
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
this.getPackageName());
startActivityForResult(recognizerIntent, 100);
// call back
onActivityResult(int requestCode, int resultCode, Intent data){...}
