[英]Recognition listener android studio, it doesn't work
我从互联网上复制了此文件,其他人则说是可行的,但是当我尝试讲话时却无济于事。
我试图在onBeginingOfSpeech()方法之外编写有关意图的代码,并且它可以工作。
public class Schermata extends ActionBarActivity implements RecognitionListener{
SpeechRecognizer speechRecognizer;
TextView test;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_schermata);
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
test = (TextView) findViewById(R.id.test);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_schermata, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onReadyForSpeech(Bundle params) {
test.setText("INIZIO");
}
@Override
public void onBeginningOfSpeech() {
test.setText("INIZIO");
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,getClass().getPackage().getName());
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
speechRecognizer.startListening(intent);
}
@Override
public void onRmsChanged(float rmsdB) {
}
@Override
public void onBufferReceived(byte[] buffer) {
}
@Override
public void onEndOfSpeech() {
test.setText("FINE");
}
@Override
public void onError(int error) {
}
@Override
public void onResults(Bundle results) {
ArrayList<String> res = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
String s = "";
for (String result : res)
s += result + "\n";
test.setText(s);
}
@Override
public void onPartialResults(Bundle partialResults) {
}
@Override
public void onEvent(int eventType, Bundle params) {
}
}
如果我理解正确,并且在inBeginningOfSpeech()之外定义了Intent时这对您有用,那么只需将其放在它的外面,将它放在那里是错误的,我将进行解释。
函数onBeginningOfSpeech()(也:onResults,onReadyForSpeech等)在识别器开始工作后即被调用,并且仅是识别器听到某人讲话的事件的回调,因此您需要准备好该意图并在调用此功能之前与识别器配对。
尝试创建一个“ initialize()”函数,该函数会在调用之前设置所有这些函数
speechRecognizer.startListening(intent);
换句话说,使用this,而不是您在'onBeginningOfSpeech()'上的内容
public void initialize(){
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,getClass().getPackage().getName());
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
speechRecognizer.startListening(intent);
}
否则,您将以错误的方式使用onResults(),则应仅提取提供给您的ArrayList的第一个String,而其他字符串只是同一语音的最差结果。
<uses-permission android:name="android.permission.RECORD_AUDIO" />
请确保您在清单中具有RECORD_AUDIO权限,否则,语音识别将无法正常工作。
