Hi, I have a use case where I would like to play a sound to let my users know that a task has completed and they can now use voice commands. I tried a very simple approach using the following in -(void) pocketsphinxDidStartListening
```
    NSString *path  = [[NSBundle mainBundle] pathForResource :kind ofType:@"wav"];
    NSURL *pathURL = [NSURL fileURLWithPath:path];
    AudioServicesCreateSystemSoundID((CFURLRef) CFBridgingRetain(pathURL), &audioEffect);
    AudioServicesPlaySystemSound(audioEffect);
```
Nothing happens. What is the accepted technique for playing a sound once pocketsphinx has started to listen?

Many Thanks!

Hello,

Sure, this has to be done in a particular way due to a bug in the PlayAndRecord audio session type – just search these forums for AVAudioPlayer and you should get a bunch of hits about how it works.

Many thanks, got it! (And I’m a bit embarrassed that it was so easy).

No worries, it’s a little counter-intuitive.
