Hello,
During an ongoing listening session I am trying to switch to another JSGF grammar using:
@property (strong) OELanguageModelGenerator *lmGenerator; ... lmPath = [self.lmGenerator pathToSuccessfullyGeneratedGrammarWithRequestedName:name]; dicPath = [self.lmGenerator pathToSuccessfullyGeneratedDictionaryWithRequestedName:name]; [[OEPocketsphinxController sharedInstance] changeLanguageModelToFile:lmPath withDictionary:dicPath];However, when I do this, I get an EXC_BAD_ACCESS as per the logs below.
Is there a solution to this problem?
Thank you,
Saliency[spoiler]

`Welcome,
Hmm, I’ve never seen that before but what jumps out at me is that it looks like the grammar is being generated after the command to switch grammars – do you have the same issue if you first create the grammar and then switch to it?
Thanks! Hmm, maybe you are encountering some buggy behavior – the crash looks like it happens when the second dictionary is being initialized, is there anything unusual about the second grammar (i.e. it’s just one word, it has some unusual punctuation, something along those lines)?
Thanks, I will check this out after the next update, but I can’t give an estimated time for that unfortunately. I appreciate the notification that there is an issue.
Hi,
No need to – you can just stop listening and start listening with your next grammar.
Hi, I just wanted to say that I’m having exactly the same problem as Saliency. The above workaround solves the crash, but the stop/start introduces other problems, so it’s not ideal.
I agree that it’s a bug and it’s been added to the issues list, but I’d be interested to hear what problems starting and stopping is causing.
I should say it can cause other problems. One example would be stopping the controller while flite is still speaking, which would result in AVAudioSession complaining about closing a session on which I/O is still happening resulting in boiler plate code in
fliteDidFinishSpeakingetc, in other words it could create a mess.OK, that makes sense that stopping while speech is in progress isn’t ideal, thanks for elaborating.
