Trigger sound play() with NSSpeechRecognizer Swift - swift

Question

I'm trying to trigger a sound after I say a word. The speech recognizer recognizes the word when I say it and I've set it up so it puts out a string each time I say the command. What I'd like to do is trigger a sound after I say that specific word. This is what I have so far.
import Cocoa
import AVFoundation
class ViewController: NSViewController, NSSpeechRecognizerDelegate {
var ping = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("ping", ofType: "mp3")!)
var pingAudioPlayer = AVAudioPlayer()
var sr = NSSpeechRecognizer()
#IBOutlet var output: NSTextView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
pingAudioPlayer = AVAudioPlayer(contentsOfURL: ping, error: nil)
sr.delegate = self
sr.commands = ["Ping", "Ping Mac"]
sr.startListening()
}
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: AnyObject?) {
output!.string! += "\(command)\n"
pingAudioPlayer.play()
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
UPDATE:
import Cocoa
import AVFoundation
class ViewController: NSViewController, NSSpeechRecognizerDelegate {
var ping = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("ping", ofType: "mp3")!)
let pingAudioPlayer = AVAudioPlayer()
var sr = NSSpeechRecognizer()
#IBOutlet var output: NSTextView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
sr.delegate = self
sr.commands = ["Ping", "Ping Mac"]
sr.startListening()
}
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: AnyObject?) {
output!.string! += "\(command)\n"
var pingAudioPlayer = AVAudioPlayer(contentsOfURL: ping, error: nil)
pingAudioPlayer.prepareToPlay()
pingAudioPlayer.play()
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
}
Not sure why the audio player is not playing the sound once the word is recognized. Any ideas?

Answer 1

You aren't telling the audio player which sound to play. Try this:
func speechRecognizer(sender: NSSpeechRecognizer, didRecognizeCommand command: AnyObject?) {
do{
let pingAudioPlayer = try AVAudioPlayer(contentsOfURL:ping)
pingAudioPlayer.prepareToPlay()
pingAudioPlayer.play()
}catch {
print("Error getting the audio file")
}
}
