[英]Recognition listener android studio, it doesn't work
我從互聯網上復制了此文件,其他人則說是可行的,但是當我嘗試講話時卻無濟於事。
我試圖在onBeginingOfSpeech()方法之外編寫有關意圖的代碼,並且它可以工作。
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) {
}
}
如果我理解正確,並且在inBeginningOfSpeech()之外定義了Intent時這對您有用,那么只需將其放在它的外面,將它放在那里是錯誤的,我將進行解釋。
函數onBeginningOfSpeech()(也:onResults,onReadyForSpeech等)在識別器開始工作后即被調用,並且僅是識別器聽到某人講話的事件的回調,因此您需要准備好該意圖並在調用此功能之前與識別器配對。
嘗試創建一個“ initialize()”函數,該函數會在調用之前設置所有這些函數
speechRecognizer.startListening(intent);
換句話說,使用this,而不是您在'onBeginningOfSpeech()'上的內容
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);
}
否則,您將以錯誤的方式使用onResults(),則應僅提取提供給您的ArrayList的第一個String,而其他字符串只是同一語音的最差結果。

請確保您在清單中具有RECORD_AUDIO權限,否則,語音識別將無法正常工作。
