每个人！我正在开发一个语音识别应用程序，该应用程序现在能够识别语音！但是，我需要在应用程序的后台运行这个语音识别代码，它必须一直听命令。对于我的应用程序，我编写了 Handler().postDelayed 函数，它计算用户登陆新活动的时间，并通过延迟 5 秒开始收听。我的问题是它只听了 2-3 秒，并且无法识别和再次听。应用程序运行时如何在应用程序后台运行语音识别？
speechRecognizer1.setRecognitionListener(new RecognitionListener() {
@Override
public void onReadyForSpeech(Bundle params) {
}
@Override
public void onBeginningOfSpeech() {
}
@Override
public void onRmsChanged(float rmsdB) {
}
@Override
public void onBufferReceived(byte[] buffer) {
}
@Override
public void onEndOfSpeech() {
}
@Override
public void onError(int error) {
}
@Override
public void onResults(Bundle bundle) {
ArrayList<String> matches1 =bundle.getStringArrayList(speechRecognizer1.RESULTS_RECOGNITION);
String string="";
if(matches1!=null) {
string = matches1.get(0);
textView3.setText(string);
Speak();
}
}
@Override
public void onPartialResults(Bundle bundle) {
}
@Override
public void onEvent(int eventType, Bundle params) {
}
});
mTTS1 = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
@Override
public void onInit(int status) {
if(status==TextToSpeech.SUCCESS){
int result= mTTS1.setLanguage(Locale.ENGLISH);
if(result== TextToSpeech.LANG_MISSING_DATA || result==TextToSpeech.LANG_NOT_SUPPORTED){
Log.e("TTS","Language Not Supported");
}
}
}
});
new Handler().postDelayed(new Runnable(){
public void run(){
speechRecognizer1.startListening(intentRecognizer1);
}
}, 5000);
