How do i delay the pocketsphinxDidDetectSpeech by 5 seconds? I’m playing some sound files during the 5 seconds and i do not want it to detect the sounds. I’ve try suspending the recognition and resuming the recognition. But how do i delay it using [self performSelector:@selector(?:) withObject:nil afterDelay:5.0f];

I’ve try putting [self.pocketsphinxController resumeRecognition]; in a function and calling it in the selector with the delay. But it failed with error unrecognized selector sent to instance.

pocketsphinxDidDetectSpeech is a delegate method, so you don’t want to delay it since you don’t call it directly, you just want to address the underlying functionality that you control directly which is whether recognition is engaged or not. Suspending recognition before playing your sound and resuming it afterwards should work perfectly for the goal of halting recognition during other media playback, so if it isn’t working perfectly we should figure out why. What happens when you suspend before you play your sound back and resume after your sound is done playing?

– (void) fliteDidFinishSpeaking {
[self.pocketsphinxController suspendRecognition];
[self performSelector:@selector(playAudioAlert:) withObject:nil afterDelay:5.0f];
}

-(void) playAudioAlert{
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:@”Audio1″ ofType:@”wav”]] error:nil];

player.delegate = self;
[self.player play];
}

-(void) audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag{
if(flag == YES){
[self.pocketsphinxController resumeRecognition];
}
}

Another question is that we can’t vibrate the phone during the sound playback right? I’ve have read some of ur previous post regarding this topic and you mention [AudioSessionManager sharedAudioSessionManager].soundMixing = TRUE; Where do i add this code? Do i need to modify the framework? Any other addition steps?

And when i input this
[AudioSessionManager sharedAudioSessionManager].soundMixing = TRUE;

the error shows
Property ‘soundMixing’ not found on object of type ‘id’

so i did this instead
[[AudioSessionManager sharedAudioSessionManager]setSoundMixing:YES];

and added this for vibration
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
to – (void) fliteDidFinishSpeaking

but it didn’t vibrate on the device.
