Increasing speech recognition accuracy using a custom languagemodel?

[jepjep7]

Hi Halle,

I have two questions:

1) I am trying to increase the speech recognition accuracy. Do you think it would help to make a custom languagemodel using the lmtool?

http://www.speech.cs.cmu.edu/tools/lmtool-new.html

2) I tried to make my own languagemodel using the lmtool instead of the built-in languagemodel generator. I ran into problems here:

NSString *lmDirectory = [NSString stringWithFormat:@”%@/words.%@”,[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0],@”languagemodel”];
NSString *dicDirectory = [NSString stringWithFormat:@”%@/words.%@”,[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0],@”dic”];

self.pathToGrammarToStartAppWith = lmDirectory;
self.pathToDictionaryToStartAppWith = dicDirectory;

When I ran this, it said that the dictionary path was null. I also noticed that this may require a .DMP file instead of a .languagemodel file. How does one use a custom .dic and .languagemodel file with the updated version of Openears?

Thank you.

[Halle Winkler]

Welcome,

Do you think it would help to make a custom languagemodel using the lmtool?

No, there is no accuracy difference between OpenEars custom models and the models from that tool, which are both generated using CMU language model generation. It would probably be more effective to share your goals and issues here and see if I can help you.

Regarding your paths being null, this just needs the normal kind of troubleshooting you’d need to do to make sure that any app bundle file path had a real file at the end of it – check that the items are really added to the target and that you’re running the target you think you are, find out where to expect an added file to be found in the bundle and how that is referenced (in this case, you look like you are trying to get a file from a caches directory, but normally a file that you add to an app target is found in the app bundle rather than the sandbox user files so I would probably start there with investigating the issue, plus you must already know the full names of your files since you named them before adding them to the bundle so that would be the second thing to look into, since your name appears to be dynamically generated), and use NSFileManager to verify the existence of your file or return an error.

OpenEars’ file loading is known to work fine using normal NSString representations of file paths, so you can just focus on figuring out why you have a null path, which is going to relate to app bundle structures/Cocoa APIs rather than OpenEars.

[jepjep7]

Thank you for your fast response, Halle. I appreciate it!

The reason I was trying to modify the languagemodel in my original post is that I thought I was having problems with number recognition, specifically “fives” and “nines”. After more testing, I narrowed down the problem. I am having problems recognizing words at the end of utterances. For example, when I try to recognize the phrase “three five five”, Openears often only recognizes “three five”. Why is that? It is almost like the last word gets cut off from being recognized.

Settings:
setVadThreshold:3.0
setSecondsOfSilenceToDetect:0.3

[Halle Winkler]

It looks like too short of a setSecondsOfSilenceToDetect, but if you want you can create a replication case for me to run:

https://www.politepix.com/forums/topic/how-to-create-a-minimal-case-for-replication/

[jepjep7]

I ran Openears Demo and it seemed to be working better than mine at recognizing numbers 1-9. So I checked my code and I had an extra “nil” on my firstLanguageArray. Here is what it looked like:

NSArray *firstLanguageArray = [[NSArray alloc] initWithArray:[NSArray arrayWithObjects:
@”ONE”,
@”TWO”,
@”THREE”,
@”FOUR”,
@”FIVE”,
@”SIX”,
@”SEVEN”,
@”EIGHT”,
@”NINE”,
nil]];

I changed the array by deleting the nil to look like this:

NSArray *firstLanguageArray = @[@”ONE”,
@”TWO”,
@”THREE”,
@”FOUR”,
@”FIVE”,
@”SIX”,
@”SEVEN”,
@”EIGHT”,
@”NINE”];

It seems to be working better now! Do you think that was it!?

Thanks.

[Halle Winkler]

I lean towards thinking it’s related to something else or maybe a small sample size, but it would be interesting to see the contents of the two generated .dic files from the Caches directory resulting from each of those arrays.

[jepjep7]

I checked, and the DIC files were exactly the same. Openears Demo is only recognizing “three five” when I say “three five five”. I will create a replication case.

[jepjep7]

I am having trouble getting saveThatWave to work.
1) I added SaveThatWaveDemo.framework to the “Frameworks” folder in the OpenEarSample App.
2) In ViewController.h, I added:
#import <SaveThatWaveDemo/OEEventsObserver+SaveThatWave.h>
#import <SaveThatWaveDemo/SaveThatWaveController.h>
@property (strong, nonatomic) SaveThatWaveController *saveThatWaveController;
3) In ViewController.m, I added:
@synthesize saveThatWaveController;

Everything complied perfectly until this point.
Then when I added this line to ViewDidLoad:
self.saveThatWaveController = [[SaveThatWaveController alloc] init];

It threw a “linker command failed with exit code 1 (use -v to see invocation)” error.

Do you have any idea why this is not working? I would like to make a test-case for the “three five five” example above. Thanks!

[Halle Winkler]

Probably there is no -ObjC linker flag added as per the instructions, but it’s necessary to copy/paste the full Xcode errors in order to troubleshoot them.

[jepjep7]

I checked and the -ObjC linker flag was already added. Here are the Xcode errors:

[Halle Winkler]

Does it work when you compile for a device? I checked the demo version of SaveThatWave and it definitely has that architecture in it, so the possibilities are that that -ObjC linker flag isn’t added to the target that is being run, or the entry for the target in the Framework Search Paths build setting that was automatically created at the time of adding the framework is incorrect or has been mangled by Xcode (this is an occasional Xcode bug), or the framework wasn’t added to the target that is being run. Otherwise there’s nothing that should be preventing it from working. Since it fails at runtime rather than compile time, I’d be suspicious of the linker flag.

[jepjep7]

Thanks- I keep trying, but it does not compile for my device.
“Other Linker Flags” is set to -ObjC in the Build Settings of the OpenEarsSampleApp target.
I checked “Framework Search Path”, and it had the “/Users/Joe/Downloads/OpenEarsDistribution/Framework” path listed.
The SaveThatWaveDemo.framework is listed in the Framework folder and is also in the filesystem.
I am running Xcode 6.4.

[Halle Winkler]

But is the plugin framework added to your target? It will show a checkmark next to the app target in the right-hand info pane.

[jepjep7]

It now complies and runs on my device, but it has a warning:

ld: warning: directory not found for option ‘-F”/Users/Joe/Downloads/OpenEarsDistribution/OpenEarsSampleApp/../Framework/”‘

[jepjep7]

Xcode quit unexpectedly today, and now there are no more linker warnings when I run SaveThatWave on my device! I suspect I should have deleted the Openears Demo from my iPhone prior to compiling and cleaned and restarted Xcode. Anyway, I am on to the next step!

I used the following line and then tested SaveThatWave on my iPhone:
[self.saveThatWaveController startSessionDebugRecord];

Where is the resultant WAV file stored? I cannot find the “caches” directory on my Mac. Thanks.

[Halle Winkler]

It’s stored on the device, in the app’s caches directory. Stack Overflow should have lots of help in getting at your app files via Xcode.

[jepjep7]

Here is my replication case. I am using an iPhone 6 running OS9 and Xcode 7.
