DragonMobile SDK SpeechKit不工作[NMSP_DEBUG]

Question

我刚刚下载了用于iOS开发的Dragon Mobile SDK，正在尝试用SpeechKit创建一个应用程序。我遵循了Dragon Mobile SDK参考，但我在日志中不断收到以下消息：

2014-12-11 23:24:52.834 TestApp[17554:1036858] [NMSP_DEBUG] nmsp_nmas_create_dictionary().
2014-12-11 23:24:52.835 TestApp[17554:1036858] [NMSP_DEBUG] nmsp_nmas_dictionary_add().
2014-12-11 23:24:52.835 TestApp[17554:1036858] [NMSP_DEBUG] nmsp_nmas_dictionary_key_exists
2014-12-11 23:24:52.835 TestApp[17554:1036858] [NMSP_DEBUG] nmsp_nmas_dictionary_add().
2014-12-11 23:24:52.836 TestApp[17554:1036858] [NMSP_DEBUG] nmsp_nmas_dictionary_key_exists

下面是我的代码：

- (IBAction)startRecording:(id)sender {
    self.vocalizer = [[SKVocalizer alloc] initWithLanguage:@"en_US"
                                                  delegate:self];

    [self.vocalizer speakString:@"Hello world."];
}

代码运行时什么也不会发生。我已经仔细检查并确保密钥是正确的，并且我已经下载了正确的框架，所以我不知道问题出在哪里。任何帮助都将不胜感激！

刚刚弄明白为什么会发生这种事！我在AppDelegate中添加了以下函数(根据Ray Wenderlich的教程)

- (void)setupSpeechKitConnection {
     [SpeechKit setupWithID:INSERT_YOUR_APPLICATION_ID_HERE
     host:INSERT_YOUR_HOST_ADDRESS_HERE
     port:INSERT_YOUR_HOST_PORT_HERE
     useSSL:NO
     delegate:nil];

     // Set earcons to play
     SKEarcon* earconStart  = [SKEarcon earconWithName:@"earcon_listening.wav"];
     SKEarcon* earconStop   = [SKEarcon earconWithName:@"earcon_done_listening.wav"];
     SKEarcon* earconCancel = [SKEarcon earconWithName:@"earcon_cancel.wav"];

     [SpeechKit setEarcon:earconStart forType:SKStartRecordingEarconType];
     [SpeechKit setEarcon:earconStop forType:SKStopRecordingEarconType];
     [SpeechKit setEarcon:earconCancel forType:SKCancelRecordingEarconType];     
}

但它没有被调用。当我把它移到ViewController中的viewDidLoad时，它开始工作了。
