    credentials.clientId = "<YOUR CLIENT ID>";
    credentials.clientSecret = "<YOUR CLIENT SECRET>";
    SR = new Bing.Speech.SpeechRecognizer("en-US", credentials);

    SR.onaudiocapturestatechanged = SR_AudioCaptureStateChanged;
}

function SR_AudioCaptureStateChanged(sender, args) {
    switch (args.State) {
        case SpeechRecognizerAudioCaptureState.Canceled:
            this.StatusBar.Text = "Operation cancelled.";
            break;
        case SpeechRecognizerAudioCaptureState.Cancelling:
            this.StatusBar.Text = "Cancelling capture operation...";
            break;
        case SpeechRecognizerAudioCaptureState.Complete:
            this.StatusBar.Text = "Audio capture complete.";
            break;
        case SpeechRecognizerAudioCaptureState.Initializing:
            this.StatusBar.Text = "Initializing audio capture...";
            break;
        case SpeechRecognizerAudioCaptureState.Listening:
            this.StatusBar.Text = "Listening...";
            break;
        case SpeechRecognizerAudioCaptureState.Thinking:
            this.StatusBar.Text = "Interpreting audio input...";
            break;
        default:
            this.StatusBar.Text = "Unknown capture state.";
