I wanted to report back that by using a flag as a switch in the callbacks (didfinishplaying and didfinishspeaking) that I used to signal when to resume or not to resume along with a very short time delay using [NSThread sleepForTimeInterval:1.3];, the app is responding very well to voice commands.

Thank you so much for your guidance, your work on this framework, and your patience. I will be sure to credit you and OpenEars in my app. I also plan to use this framework in the future. Thanks again!

Again you have stimulated my thoughts and increased my knowledge. I believe after some experiments that one of my problems is calling the speech utterance several times in succession. The timing just seems to get out of whack since I was suspending and resuming after each. I am combining the multiple utterances into a single one. I will also look at the audio files. It seems that I was resuming recognition in between speech calls causing some recognition of the second speech. Thanks for your guidance. I will be back in touch in the future with questions and progress.

Please forgive my coding I know it needs work. Thanks.

OK I have a few more questions. The first time I call the [self.pocketSphinxController suspendRecognition]; is while I am still in the ViewDidLoad right before the speech synthesizer is speaking the introductory remarks. It causes a Thread 1:EXC_BAD_ACCESS (Code=1, address=0x4c). If I comment out the call the program runs through but I encounter a false recognition. Here is the listing of the output:

The third BET and the last BALANCE were both recognitions that were not spoken. Any ideas or pointers would be greatly appreciated. Thank you very much.

Thanks so much for your tutorial. I believe I understand where to place the suspend and to locate the resume in the delegates that are called when audio and speech are completed. I have implemented all of the delegates but I am still having an issue. It seems that my app works but still has an occasional double, triple, or more hypothesis. I am still doing testing to find any places in the code that I may have overlooked. In another day or two I should have it narrowed down. If I continue to have difficulty I will provide the verbose logging info and let you know.

Again I cannot express my gratitude enough for your patience and explanation. I feel I have learned so much. I want to continue using OpenEars in other apps I hope to develop. Thanks again, I will be back in touch with the results.

Sorry for being slow but I believe your second question about the suspend/resume holds the answer to my problem. I am using this code to determine the event from the hypothesis:

- (void) pocketsphinxDidReceiveHypothesis:(NSString *)hypothesis recognitionScore:(NSString *)recognitionScore utteranceID:(NSString *)utteranceID {
    NSLog(@"The received hypothesis is %@ with a score of %@ and an ID of %@", hypothesis, recognitionScore, utteranceID);
    
    if ([hypothesis isEqualToString:@"HELP"])  {
        [self slotHelp:self];
    }
    if ([hypothesis isEqualToString:@"BET"]) {
        [self slotBet:self];
    }
    if ([hypothesis isEqualToString:@"SPIN"]) {
        [self slotSpin:self];
    }
    if ([hypothesis isEqualToString:@"BALANCE"]) {
        [self slotScore:self];
    }
}

During each event there is speech from both TTS and audioPlayer. I use this conditional to test when there is no speech at the beginning of each event but am not sure where to suspend and resume:

if (self.synthesizer.speaking == NO && ![audioPlayer1 isPlaying] && ![audioPlayer2 isPlaying] && ![audioPlayer3 isPlaying] && ![audioPlayer4 isPlaying]) {
// no speech currently
}

I thought I could suspend recognition after this conditional and let the event take place but I am not sure where or how to resume recognition after the speech is completed.

Thanks so much for your patience and help. I am hoping to develop several apps using OpenEars for people who are visually challenged. OpenEars is a vital part of my vision. Again thanks for your help.

I just tried it on the ipad 2 and had the same problem. It gave a hypothesis of 8 words when no speech was occuring Then when I used and it detected a correct word it also detected (gave a hypothesis) of the same word a second and third time when there was no spoken word. Maybe it is getting some feed from the game speech or audio?

I am writing and testing the app for iphone and ipad. I have observed this behavior on the ipod touch and in the simulator. I am currently testing on the ipad. Thanks for your quick response.
