The title it's not clear i think. In my project i want a service that runs in background and when the user says "hello phone" or some word/phrase my app starts to recognize the voice. Actually it "works" but not in right way... I have a service and this service detect the voice.
public class SpeechActivationService extends Service
{
protected AudioManager mAudioManager;

super.onCreate();

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());
//mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
}
protected static class IncomingHandler extends Handler
{
private WeakReference<SpeechActivationService> mtarget;
IncomingHandler(SpeechActivationService target)
{
mtarget = new WeakReference<SpeechActivationService>(target);

switch (msg.what)

And i start service in my MainActivity just to try:
Intent i = new Intent(context, SpeechActivationService.class);
startService(i);
It detect the voice input...and TOO MUCH!!! Every time it detects something it's a "bipbip". Too many bips!! It's frustrating.. I only want that it starts when i say "hello phone" or "start" or a specific word!! I try to look at this https://github.com/gast-lib/gast-lib/blob/master/library/src/root/gast/speech/activation/WordActivator.java but really i don't know how use this library. I try see this question onCreate of android service not called but i not understand exactly what i have to do.. Anyway, i already import the gast library.. I only need to know how use it. Anyone can help me step by step? Thanks
