делать действия после распознавания звука в Android
пожалуйста, дайте мне предложение об этом условии. Возможно ли в Android, что устройство ожидает особого звука, и после того, как оно его распознает, происходят некоторые действия. Пожалуйста, расскажите мне о своих идеях. Спасибо за вашу помощь!
ОБНОВИТЬ я пробую карманного сфинкса и много раз ищу «определение нового ключевого слова», но не могу. Я использую этот код:
public class PracticeActivity extends Activity implements RecognitionListener, edu.cmu.pocketsphinx.RecognitionListener {
// private static final String KWS_SEARCH = "wakeup";
// private static final String KEYPHRASE = "listen"; //adjust this keyphrase!
//3-
private static final String DIGITS_SEARCH = "digits";
private edu.cmu.pocketsphinx.SpeechRecognizer recognizer;
private MediaPlayer mediaPlayer;
@Override
public void onCreate(Bundle state) {
super.onCreate(state);
setContentView(R.layout.practice);
((TextView) findViewById(R.id.caption_text))
.setText("Preparing the recognizer");
new AsyncTask<Void, Void, Exception>() {
@Override
protected Exception doInBackground(Void... params) {
try {
Assets assets = new Assets(PracticeActivity.this);
File assetDir = assets.syncAssets();
setupRecognizer(assetDir);
} catch (IOException e) {
return e;
}
return null;
}
@Override
protected void onPostExecute(Exception result) {
if (result != null) {
((TextView) findViewById(R.id.caption_text))
.setText("Failed to init recognizer " + result);
} else {
recognizer.startListening(DIGITS_SEARCH);
}
}
}.execute();
}
@Override
public void onDestroy() {
super.onDestroy();
recognizer.cancel();
recognizer.shutdown();
}
/**
* In partial result we get quick updates about current hypothesis. In
* keyword spotting mode we can react here, in other modes we need to wait
* for final result in onResult.
*/
@Override
public void onPartialResult(Hypothesis hypothesis) {
if (hypothesis == null)
return;
String text = hypothesis.getHypstr();
if (text.equals("my phone")) {
((TextView) findViewById(R.id.result_text))
.setText(text);
findViewById(R.id.result).setVisibility(View.VISIBLE);
/* recognizer.cancel();
recognizer.startListening(KWS_SEARCH);*/
}else if (text.equals("where is my phone")){
((TextView) findViewById(R.id.caption_text))
.setText(text);
((TextView) findViewById(R.id.result_text))
.setText("i am here");
}else
recognizer.startListening(DIGITS_SEARCH);
}
@Override
public void onResult(Hypothesis hypothesis) {
}
@Override
public void onReadyForSpeech(Bundle params) {
}
@Override
public void onBeginningOfSpeech() {

@Override
public void onRmsChanged(float rmsdB) {

@Override

@Override

private void setupRecognizer(File assetsDir) throws IOException {
File modelsDir = new File(assetsDir, "models");
// The recognizer can be configured to perform multiple searches
// of different kind and switch between them
recognizer = defaultSetup()
.setAcousticModel(new File(assetsDir, "en-us-ptm"))
.setDictionary(new File(assetsDir, "cmudict-en-us.dict"))
.getRecognizer();
recognizer.addListener(this);
/*/2-
File digitsGrammar = new File(modelsDir, "grammar/digits.gram");
recognizer.addKeyphraseSearch(KWS_SEARCH, KEYPHRASE);*/
//3-
File digitsGrammar = new File(modelsDir, "grammar/digits.gram");
recognizer.addKeywordSearch(DIGITS_SEARCH, digitsGrammar);
}
@Override
public void onError(Exception error) {
((TextView) findViewById(R.id.caption_text)).setText(error.getMessage());
}
и это дляdigits.gram
my phone /1e-1/
это происходит как бег:
