I’ve tried this with my own app, could not figure out why it was crashing, then attempted on the OpenEarsSampleApp that came with the framework, and it did the same thing.

Here’s what I attempted:
Take the sample app.
Copy the ‘OpenEars1.gram” and “OpenEars2.gram” files into the project folder.
Right before the

[self.pocketsphinxController startListeningWithLanguageModelAtPath:self.pathToGrammarToStartAppWith dictionaryAtPath:self.pathToDictionaryToStartAppWith languageModelIsJSGF:FALSE];

call, I changed the path with a new variable that grabs the grammar file from the bundle.

NSString *jsgfPath = [[NSBundle mainBundle]pathForResource:@"OpenEars2" ofType:@"gram"];
[self.pocketsphinxController startListeningWithLanguageModelAtPath:jsgfPath dictionaryAtPath:self.pathToDictionaryToStartAppWith languageModelIsJSGF:TRUE];

Soon as calibration finishes, this triggers a crash. Is there more to enabling JSGF that I seem to be missing?

Thanks

Switching to OpenEars1.gram seems to work, now just trying to see if that’s the same problem my project had.

I was trying to use the example JSGF example from CMUSphinx’s page, which is

#JSGF V1.0;
grammar samplegrammar;
public = ;
= ;
= /10/ open |/2/ close |/1/ delete |/1/ move;
= [the | a] (window | file | menu);
= (please | kindly | could you | oh mighty computer) *;
= [ please | thanks | thank you ];


and it was throwing an index out of bounds exception. If I change it to a more direct set of phrases

#JSGF V1.0;
grammar samplegrammar;
public =
OPEN THE WINDOW |
CLOSE THE WINDOW |
DELETE THE WINDOW |
DELETE THE FILE |
CLOSE THE FILE;


It seems to work fine. Honestly though, I can probably get away with simple phrase detection like this for this project.

EDIT: the tags were parsing out of the CMU code here, but the example on the page still lists it.

ERROR: “jsgf_parser.y”, line 155: syntax error, unexpected RULENAME, expecting TOKEN or ‘;’ at line 3 current token ”

Any advice is appreciated

Thanks
