With OpenEars-only (original grammar without any plugin):

I have false-positives and I have false negatives. I feel that it does a tiny bit better as for the false-negatives than Rejecto. But I would have to test much more thorougly.

I suggest that I place more logs for each of the solutions. (since again, for me this logs are very cryptic).

But let me first place the Accoustic Model Creation Code of the non-plugin OpenEars-only solution to have everything mentioned here.

[iKK]

With Rejecto: What I don’t understand why the ending of my “sentence at question” does not seem to matter at all. i.e. if I speak “eschdonofrey” or if I speak “eschdonoAnything” makes no difference, the sentence is still recognized (which leads to so many false-negatives !

Do you have any idea on how to improve the ending-problem of my sentence at question ?

[iKK]

OK – let’s continue with Rejecto !

[iKK]

For both solutions (Rejecto or RuleORama) my question to you: Are you able to interpret the logs in order to tune one or the other solution even more ? I am completely lost in what to tune here since the logs look very cryptic to me.

If yes, what examples should I place ? (positive, false-positive or false negative ones?

[iKK]

Thank you – also the RuleORama is now performing !

Unfortunately, it still has many false negatives.

Also, one thing I don’t understand is that it often times responds with having recognized the “sentence at question” several times. As can be seen in this log-excert:

2018-04-26 17:12:25.815209+0200 TestOpenEars[1012:281905] Pocketsphinx heard "esch do no frey esch do no frey esch do no frey esch do no frey esch do no frey" with a score of (-130134) and an utterance ID of 19.
Local callback: The received hypothesis is esch do no frey esch do no frey esch do no frey esch do no frey esch do no frey with a score of -130134 and an ID of 19

What could this be ? i.e. Why does the hypothesis contain our “sentence at question” this many times ??

[iKK]

Thank you for the explanation – I will investigate in the “0.1 < withWeight < 1.9” parameter as well as play with the two LookupList.text suggestions (maybe even play with that one also a little bit to understand its effects…)….

Can we now approach the RuleORama error ?

I feel that having both up’n’running (Rejecto and RuleORama) would help to compare the solutions to find the best approach.

Here is the Language-model creation of RuleORama (see next forum-entry) and its Error-log (see after-next forum-entry).

This helped !

This is the first time Rejecto seems to peform :) Thank you very much !

Now, I tested both A) and B) and it indeed makes a slight difference.

A)

es	ee s
eschdonofrey	@ ss d oo n oo f r @ ii
esf	ee s f

B)

es  ee s
eschdonofrey    ee ss d oo n oo f r ee ii
esf ee s f

As for A, this seems to perform slightly better than B.

However, even for A there are many false-positives ! And also 1 out of 10 is a false-negative (which I never had in any of the previous tests).

At least, this is something to play now….

One question:
What does the symbol “@” represent in the LookupList.text ? (the double-ee’s and double-ii’s I can somehow intereprete but what does “@” really mean ?)

I did the two changes but same thing – still an error in Rejecto log !

(–> see next forum entry for its log)
(–> see after next forum entry for the language model creation as it looks now)

What else is to change ??

And the Rejecto error-log when let words = ["eschdonofrey"]

Ok – all in this forum:

Lets continue with Rejecto:

(I changed the AcousticModelGerman.bundle/LanguageModelGeneratorLookupList.text to what you suggested).

You wrote last: so that it just creates a model for the single word “eschdonofrey”

This makes me do :

let words = ["eschdonofrey"]

…with its language-model creation as can be seen in the next Forum-entry (for clarity I place this in a new forum-entry)

But this leads to an error as can be seen in its log
(–> also this log is placed in its separate forum-entry to make things easier to read)

If I change the words-array back to let words = ["esch do no frey"] then there is no error – but I feel that I did not fully follow your instructions.

What is the correct words-array for Rejecto and our new LanguageModelGeneratorLookupList.text ???

If it is let words = ["eschdonofrey"] then what is the counter-measure to its error ??

[iKK]

Ok – I just feel that the log and VC’s Code make the forum trememdous. And links would be nicer somehow. I can put it into a new github-reop if you prefer. Or I can paste the huge logs in this forum. What do you prefer ?

[iKK]

The forum entries I submit are no longer shown (in none of my browsers…). This is unfortunate. Can you still read them ??

2018-04-24 15:26:59.577309+0300 TestOpenEars[5111:2385157] The word no was not found in the dictionary of the acoustic model /var/containers/Bundle/Application/EF8E1618-8403-456C-8666-01B9C11D392E/TestOpenEars.app/AcousticModelGerman.bundle. Now using the fallback method to look it up. If this is happening more frequently than you would expect, likely causes can be that you are entering words in another language from the one you are recognizing, or that there are symbols (including numbers) that need to be spelled out or cleaned up, or you are using your own acoustic model and there is an issue with either its phonetic dictionary or it lacks a g2p file. Please get in touch at the forums for assistance with the last two possible issues.

Ok, I have everything ready again (thanks to TimeMachine ;) – …since I had the OpenEar-only version deleted on git.

1) OpenEars only with German-accModel and Logging (= version as in your Link – except moved the logging right after viewDidLoad)

2) OpenEars with Rejecto and German-accModel (with logging right after viewDidLoad)

3) OpenEars with RuleORama with German-accModel (with logging right after viewDidLoad but still with a bug that I don’t know on how to correct – see above log)

In the next forum-entry I place the requested Log from the OpenEars-only version that you asked for. If more logs are needed let me know, ok ?

[iKK]

Sorry – need to answer you this tomorrow. I don’t think I do have this project anymore in this state as it was… Please let me check tomorrow, ok?

Feel free to copy and paste this code for your path to your grammar, but remember to replace the part that says "TheNameIChoseForMyVocabulary" with the name you actually chose for your grammar or you will get this error again (and replace myLanguageModelGenerator with the name of your OELanguageModelGenerator instance).

I am sorry about my tone during RuleORama-demo-trials today – I felt a bit stressed out since things did not fit immediately :/ I do appreciate your help !

As requested, I did move the log-code accordingly (i..e after viewDidLoad).

Please see the following two forum-entries for the two Logs

(1) : Done by Rejecto
–> There are 5 times I spoke, the two first times are spoken correctly (i.e. our words-array) – the thrid, fourth and fitht time is spoken incorrectly (but unfortunately still recognized by Rejecto)

(2) : Done by RuleORama
–> Still, there is a bug in code as can be read in the log…

[iKK]

My RuleORama-VC looks like this:

Additionally, I
– inserted the RuleORama-Framework
– set Other Linker Flags to -ObjC
– set the Bridging-Header Path correctly

Here is the Code:

With RuleORama, I end up with the following error (see log below). Can you please tell me what is still wrong ? And also, how does the words-array now need to look like. It seems that RuleORama wants a different one ???

Here is the RuleORama-log: (..still not sure if I translated all ObjC-Code from the manual correctly to Swift)….

with a languageModelPath which is nil. If your call to OELanguageModelGenerator did not return an error when you generated this grammar, that means the correct path to your grammar that you should pass to this method's languageModelPath argument is as follows:

NSString *correctPathToMyLanguageModelFile = [myLanguageModelGenerator pathToSuccessfullyGeneratedGrammarWithRequestedName:@"TheNameIChoseForMyVocabulary"];

Feel free to copy and paste this code for your path to your grammar, but remember to replace the part that says "TheNameIChoseForMyVocabulary" with the name you actually chose for your grammar or you will get this error again (and replace myLanguageModelGenerator with the name of your OELanguageModelGenerator instance). Since this file is required, expect an exception or undocumented behavior shortly.

[iKK]

Halle,
can we please continue with Rejecto. I relaize the RuleORama-demo is again not useful after download – and I feel that I loose trememdeous amount of time just to set up these demo-projects. Also, your manual contains ObjC-Code under the Swift3 chapter – which is not something pleasant either. Can you please provide me with a working RuleORama-demo (Swift4) or we continue with Rejecto. Let me know, ok?

[iKK]

In principle, we can continue with RuleORama. However, since costs are three times as much, I would of course prefer Rejecto somewhat.

I propose, we make tests with both and decide then on the better outcome, ok? As long as I can test using a free testing license for both of the technologies, we can go ahead comparing.

I downloaded RuleORama test-version. Give me a moment to set it up, ok. After that we have both technologies to play with.

[iKK]

Here are the logs:
Logs

I did 2 Log-files: The first one contains logs of correctly spoken sentences. The second one contains logs from incorrectly spoken but unfortunately still recognised sentences.

Also, the link shows a third File which is the ViewController.swift-File containing hopefully all you need in terms of the required “generation of my language model”…

[iKK]

Yes, it was confusing.

And also, I am not asking you for debugging. I am asking you on how to apply the view settings OpenEars offers to get the recognition-success-rate (and specificity!) to an order where it is acceptable for production.

So – is there anymore settings I can do in order to improve specificity for our one-sentece words-array ?

[iKK]

Here is the link to the the test-project you asked for (an entirely new project with the tutorial only using the approach we’ve chosen here (a grammar using stock OpenEars and the German acoustic model)):

Test Project OpenEars with German-Acc.Model

Unfortunately, I observe still the very same issue as before with my other tests. (i.e. too many sentences are recognized that have nothing to do with the one provided in the words-array).

Can you please help any further here ??

[iKK]

H Halle,
I completed a test-example completely from scratch. Please refer to my email. Hope to hear from you soon.

[iKK]

Sorry – yes, of course. I have too many versions going on.

I do have it the way you just stated ! But same issue…

[iKK]

sorry typo: it sais:

words = [“esch”, “da”, “no”, “fey”]

[iKK]

The words array sais

words = [“esch” “da” “no” “fey”]

[iKK]

Sure:

func startListening()
{
if OEPocketsphinxController.sharedInstance().isListening {
stopListening()
}

var acousticModelName = “AcousticModelGerman”
var fileName = “GermanModel”

OEPocketsphinxController.sharedInstance().vadThreshold = 3.6;

var error: Error?

error = lmGenerator.generateGrammar(from: [OneOfTheseWillBeSaidOnce : words], withFilesNamed: fileName, forAcousticModelAtPath: OEAcousticModel.path(toModel: acousticModelName))

var lmPath = “”
var dictPath = “”

if(error == nil) {

lmPath = lmGenerator.pathToSuccessfullyGeneratedLanguageModel(withRequestedName: fileName)
dictPath = lmGenerator.pathToSuccessfullyGeneratedDictionary(withRequestedName: fileName)
lmPath = lmGenerator.pathToSuccessfullyGeneratedGrammar(withRequestedName: fileName)

} else {
print(“Error: \(error!.localizedDescription)”)
}

try? OEPocketsphinxController.sharedInstance().setActive(true)
OEPocketsphinxController.sharedInstance().startListeningWithLanguageModel(atPath: lmPath, dictionaryAtPath: dictPath, acousticModelAtPath: OEAcousticModel.path(toModel: acousticModelName), languageModelIsJSGF: true)
}

[iKK]

Same issue: The sentence is recognized 100% – but many more sentences having a similar lenght. For example I speak the sentence with the last (of the four) words replace by another word – and the grammar method still recognizes the sentence, unfortunately!

[iKK]

And also, what is the vadThreshold value for German ?

[iKK]

Is it one word as a single element in the array – or rather 4 words as a single string-array element ??

[iKK]

Yes !

[iKK]

It is not as an articulated language like German.

[iKK]

It is just spoken without break inbetween the words and also some letters are ommitted at the beginning of each single word (which is possible in Swiss german)

[iKK]

ok – it is hard to explain :) But let’s imagine the german sentence “Wir sind Wir” and then it is spoken “MiaSanMia” :)

[iKK]

The thing is that the Swiss-german short sentence only consists of 4 words. And in 99% of the time they are spoken in such a fast manner that is sounds like ONE long word. There is some background-noise (imagine a train-station-kind-of background-noise).

What do you suggest for this use-case ? (grammar vs. Rejecto) ? You are the expert :)

[iKK]

About the decision – it is hard since both its documentation advertize what is needed in my case :

–> generateGrammar sais: “This will recognize exact phrases instead of probabilistically recognizing word combinations in any sequence.”

–> Rejecto’s doc sais: “Rejecto makes sure that your speech app does not attempt to recognize words which are not part of your vocabulary. This lets your app stick to listening for just the words it knows, and that makes your users happy.”

Therefore both seem to be necessary somehow – what choice do you suggest. Or can you even use both at the same time ??

[iKK]

I was using only one Accoustic-model at the time (but happen to try English and Spanish so far). And no – there is no reason (anymore) to not also try with the German-Accoustic model – in fact I just did 5 Minutes ago. (we did have other products evaluated in EnglishOrSpanish and therefore the choice of EnglishOrSpanish so far…)

About grammar vs. Rejecto: You tell me what suits better for this kind of problem ??? (i.e. recognising a Swiss-german short sentence with highest specificity)
