Double commands in hypothesis

[cricketgeek]

Using the code from the tutorial and OpenEars demo app everything is working great except I seem to get double commands inside of pocketsphinxDidReceiveHypothesis for the hypothesis sometimes even though I’m very carefully saying the command once. Actually, sometimes there are other words from my generated grammar and dictionary, like “RIGHT GO” or “LEFT GO STOP” when “GO” was spoken.

Tried
[self.pocketSphinxController setSecondsOfSilenceToDetect:0.6];
and then also
[self.pocketSphinxController setNBestNumber:1];
[self.pocketSphinxController setReturnNbest:YES];

other than cleaning the result up myself is there something I can tweak to get this only returning the best match and 1 result?

[Halle Winkler]

Any chance you’re testing on the Simulator?

[cricketgeek]

No, testing through an iPad 3. And I noticed this time that after I get the extra words in hypothesis, if I try again it usually works and only returns the 1 word, “STOP” or “GO”. I am using the demo version which I just downloaded yesterday (probably obvious from my noob question here).

[Halle Winkler]

OK, is it happening on the first hypothesis of the session or does it also happen afterwards?

[Halle Winkler]

Oh, another question — you posted this in the OpenEars plugins section, but from the info in the question I’ve been assuming that the question is actually about OpenEars without a plugin. Is this incorrect and the question is about one of the OpenEars plugins, or is it just about OpenEars itself?

[cricketgeek]

Ok, yes I thought I was using Rejecto but I was not yet using anything in that area.
So I think this is just OpenEars.
This happens after the first hypothesis. Once I got “STOP” “LEFT” “STOP” “GO” “STOP” from just saying “STOP” once

Anything wrong with the way the grammar and dictionary are setup?
NSArray *words = @[@”LEFT”,@”RIGHT”,@”GO”,@”STOP”,@”FINISH”,@”KILL”];
NSString *name = @”commandLanguageModelFile.languagemodel”;
NSError *error = [lmGenerator generateLanguageModelFromArray:words withFilesNamed:name];

NSDictionary *languageGeneratorResults = nil;

if ([error code] == noErr)
{
languageGeneratorResults = [error userInfo];
self.pathToDynamicallyGeneratedGrammar = [languageGeneratorResults objectForKey:@”LMPath”];
self.pathToDynamicallyGeneratedDictionary = [languageGeneratorResults objectForKey:@”DictionaryPath”];

[self startListening];
}
else
{
NSLog(@”Error: %@”,[error localizedDescription]);
}

[Halle Winkler]

OK, that sounds a bit buggy. It’s possibly an iPad 3 issue with the cmninit value that we could probably fix right now. Your code looks reasonable to me.

Can I ask you to turn on verbosePocketsphinx and verboseLanguageModelGenerator and OpenEarsLogging and then print the log here? I’d like to see a log for 5 recognition rounds and it would be great if you would separately tell me what you really said.

[Halle Winkler]

Also let me know which mic you are using when you’re getting these results and how far you are from the device, thanks.

[cricketgeek]

Ok, will do this evening or tomorrow morning. I am using the built-in mic at the top of the iPad. Also one thing I found by going through the official demo code was that after making the call below it worked perfectly. So I plugged that into my demo code just to see and it also worked perfectly every time.

[self.pocketSphinxController changeLanguageModelToFile:self.pathToDynamicallyGeneratedGrammar withDictionary:self.pathToDynamicallyGeneratedDictionary];

[Halle Winkler]

That’s funny, thanks for letting me know. It’s a big hint about what the underlying issue might be and I’m glad you have a workaround for now. When you get the time to send me the full log output I will see if I can track down the issue.

[cricketgeek]

Now I’m using this codebase on iPhone 5 and getting groups of words when I say one word and pause. Such as LEFT ends up being a hypothesis of LEFT GO and RIGHT turns into RIGHT GO RIGHT

OK, thanks for the logging. I’ve never received a report of this issue before (not that I don’t believe it, just that it’s not a common issue) and the OS and device you’re using is part of the testbed, so I think I’d want to check out the app code in order to learn more about what is happening — would it be possible for you to make a stripped-down sample app that manifests the issue to send me so I can see it?
