    Hi,
    I am trying to recognise a short command-sentence in Swiss-german language.
    The command consists of 4 words only. The goal is to recognize only this command (and nothing else) in my iOS-App.

    I have OpenEars running doing the following:

    1.) Use OpenEar’s “generateGrammar” method together with a “words”-array and the dict-setting “[OneOfTheseWillBeSaidOnce : words]”

    2. Use the “AcousticModelEnglish” and set the “words” array with ‘fictive words”, such that if these words are spoken in English they will sound like the Swiss-german command-sentence. There are approx 20 Words and approx. 10 Sentences provided inside the “words” array. (for all applies: if spoken in English they sound like the Swiss-german command sentence)

    3. Alternatively the same thing for the “AcousticModelSpanish” (with a different “words” array

    4. Since yesterday, I tried also the Rejecto-Plugin (using its Rejecto-method “generateRejectingLanguageModel” instead of “generateGrammer”)…

    But for all of the above variations, there is a problem: Too much is recognized.
    Which means, the Swiss-german command-sentence is recognized at 100% but unfortunately many many other words and sentences are recognized as well. (i.e. the recognition is not specific enough !).

    What could I do to improve the recognition specificity for this Swiss-german command-sentence ????

    Any help appreciated.

    Welcome,

    Let’s just troubleshoot one case if that’s OK – two languages and two different vocabulary structures might get a little confusing. Would you rather troubleshoot your grammar, or the Rejecto model? BTW, maybe this goal would be a better match for the German acoustic model.

    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)

    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 ??

    OK, well, let’s just pick a single Acoustic Model for this troubleshooting case so that we don’t have a lot of variables – you can tell me which one we’re using. I recommend the German one.

    –> 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.”

    Yes, the intention of this documentation is to clarify that a grammar can listen for a multi-word phrase in exclusive terms (i.e. it won’t attempt to evaluate statistical nearness to your phrase but just try to hear it when complete, not hear it when not complete) and Rejecto will reject unknown words from a model made up of words. So if the goal is a sentence, a grammar is probably the right choice. If you were looking for one of several words by themselves, or phrases where you didn’t mind possible partial recognition of the phrase contents, Rejecto would be better.

    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 :)

    Sorry, it’s difficult for me to imagine this case without an example. Can you share with me something similar enough so I can understand how a four-word phrase can sound like a single word when spoken?

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

    #1032306

    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)

    It is not as an articulated language like German.

    I see, the aspect where it sounds like a single word is a standard characteristic of spoken Schweizerdeutsch for a sentence this short and simple, is that correct?

    Got it, thank you for explaining. OK, let’s first try and see whether the simplest thing works, and then we can explore other ways if it doesn’t. Let’s start with using a grammar with the German acoustic model and see how far we get. What are your results when you do that? You grammar should have the whole sentence as a single string as a single array item in your dictionary, not an array of individual words.

    #1032311

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

    #1032312

    And also, what is the vadThreshold value for German ?

    An array with a single element, which is a string containing four words with spaces between them.

    #1032314

    And also, what is the vadThreshold value for German ?

    This always has to be tested out on your end of things for your usage case (doing this will also help with your background noise issue, with luck). I think there is a note about it at the bottom of the acoustic model page with more info.

    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!

    OK, can you show me the shortest possible code excerpt (i.e. just the part where you create the grammar and start listening for it, making absolutely sure that none of your other troubleshooting attempts are still also in effect), replacing the four words with a different four words if you need to for confidentiality?

    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)
    }

    I would also need to see the content of the array words, even if each word has been substituted with another word.

    OK, I’m a bit worried that there is cross-contamination with your multiple troubleshooting approaches in the code you are working with and showing me (I’ve touched on this concern a couple of times in this discussion so far because it is a common situation after the developer has tried many things), so I think I’d like to try to rule that out before we continue.

    Could you put away your existing work and zip it into an archive somewhere for the time being, and then make 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), and do it with four words from the start where you would be comfortable sharing all the vocabulary and listening initialization code with me and 100% of the logging output? Then we can continue without worrying about replacing words or old code hanging around. Thanks!

    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 ??

    Hi, sorry, I really don’t run projects locally for this kind of troubleshooting – I can only ask for your logging output and code excerpts as I have time to assist. I asked you to make a new project so we could be sure we were not mixing your old approaches because your old code was entering into the troubleshooting process, but I apologize if this was confusing about the question of whether I would be running the test project locally and debugging it myself.

    #1032336

    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 ?

    OK, can you now run this project and show me all of the logging output (with no edits at all) requested in this post: https://www.politepix.com/forums/topic/install-issues-and-their-solutions/ and then show me the code excerpt I asked for above which includes the generation of your language model? Thanks!

    I’d also like to take this opportunity to remind that even when we start discussing Rejecto- or RuleORama-related issues, the license of the plugins does not allow them to be redistributed anywhere, so make sure not to post the demos or licensed versions of those products anywhere like Github or anywhere else which enables sharing.

    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”…

    Super, we can test a couple of things now that we’ve level-set. First question: would it be possible for you to use RuleORama, or is Rejecto the only plugin you would like to test with? I’m asking because the easiest first step is to see if your results are better with RuleORama because you already have a working grammar, but if you don’t want to use it, we can skip it and try something with Rejecto.

    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.

    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?

    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)….

    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.

    Hi,

    A few things to clarify:

    • it is of course completely fine if you don’t want to use RuleORama, which is the reason I asked first if it was OK for you. This is not an upsell – my question was because there is no easier time to try it out then right after you have set up a grammar, and if you wanted to hear all the options, this was the most convenient moment to explore that one and any other timing will be less convenient because we will be changing from a grammar to a language model afterwards. My intention was to explain to you how to add it to your existing project if you agreed to try it out. It is fine with me either to skip it or to take time to get it working.

    • This is too unconstructive for me while I’m working hard to give you fast and helpful support for an unsupported language, and I’d appreciate it if you’d consider that we both have stresses in this process: “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.” I disagree with you about the origin of the issues in this case, but more importantly, I just don’t want to proceed with this tone, which also seemed to come up due to my trying hard to remove all the unknown variables from our troubleshooting process, and I’m likely to choose to close the question if it is an ongoing thing even though we’ve both invested time in it. You don’t have to agree, but I don’t want you to be surprised if I close this discussion for this reason.

    • I want to warn you here that it is possible there is no great solution because this is an unsupported language, so that you have enough info to know whether to invest more time. I am happy to help, and I have some theories about how we might be able to make this work, but not every question has a perfect answer.

    That all said, I just noticed from your RuleORama install that there is something we need to fix in both installs, which is that in both cases the logging is being called too late to log the results of generating the language model or grammar. Can you move these:

    OELogging.startOpenEarsLogging() //Uncomment to receive full OpenEars logging in case of any unexpected results.
    OEPocketsphinxController.sharedInstance().verbosePocketSphinx = true

    To run right after super.viewDidLoad() and share the logging output from both projects?

    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…

    Cool, thank you. Do you have a log for your earlier project that is just OpenEars using a grammar (without Rejecto), with the logging calls moved to the top? I thought that was the main file we had starting with debugging above, and then we were going to quickly try out RuleORama if you wanted. Those two grammar-using projects are the ones I’m curious about right now, because it looks like there is a flaw in the grammar and I want to know if the same error is happening in both.

    I’m talking about the project which uses this VC: https://www.politepix.com/forums/topic/recognize-short-command-in-nonenglish/#post-1032343

    Except moving the logging calls high enough up so that we can see any errors that happen while you’re generating the grammar.

    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?

    No problem, just keep in mind that I asked for that project to have a clean slate to work from without mixing up code from multiple approaches, so we want to get back to that state of clarity and simplicity.

    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 ?

    OK, let’s see what happens when you make the following changes to the three projects.

    For your regular grammar project and for your RuleORama project, please adjust this code:

    
            let words = ["esch do no frey"]
            
            // let err: Error! = lmGenerator.generateLanguageModel(from: words, withFilesNamed: name, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))
            
            // let err: Error! = lmGenerator.generateGrammar(from: [OneOfTheseWillBeSaidOnce : words], withFilesNamed: fileName, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))
            
            let err: Error! = lmGenerator.generateFastGrammar(from: [OneOfTheseWillBeSaidOnce : words], withFilesNamed: fileName, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))

    so it matches the grammar instructions with the enclosing ThisWillBeSaidOnce declaration like so:

    
            let words = ["esch do no frey"]
            let grammar = [
    			ThisWillBeSaidOnce : [
    				[ OneOfTheseWillBeSaidOnce : words]
    			]
    		]
    
            // let err: Error! = lmGenerator.generateGrammar(from: grammar, withFilesNamed: fileName, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))
            
            let err: Error! = lmGenerator.generateFastGrammar(from: grammar, withFilesNamed: fileName, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))

    Uncommenting whichever of the generateGrammar/generateFastGrammar lines are to be used by the respective grammar project.

    For your Rejecto project, please open AcousticModelGerman.bundle/LanguageModelGeneratorLookupList.text at whatever location you are really linking to it (please be ABSOLUTELY sure you are performing this change on the real acoustic model that your project links to and moves into your app bundle, wherever that is located, or our troubleshooting work on this project will be guaranteed to be unsuccessful) and look for the following two lines:

    es	ee s
    esf	ee s f

    and change them to this:

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

    and then you have to change your Rejecto language model generation code (which you have never shown me here) so that it just creates a model for the single word “eschdonofrey”. Do not make this change to your grammar projects. For contrast, you can also try changing the acoustic model entry to this instead with your Rejecto project, with slightly different phonemes:

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

    If none of these have better results, this will be the point at which we will have to stop the troubleshooting process, because it is guaranteed to get confused results if we try to further troubleshoot three different implementations in parallel which have hosted other different implementations at different times. If one of these projects has improved results, we can do a little bit more investigation of it, under the condition that the other two projects are put away and it is possible for me to rely on the fact that we are only investigating one clean project at a time moving forward. Let me know how it goes!

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

    They are being marked as spam due to the multiple external links. Please keep all the discussion in here so it is a useful resource to other people with the same issue. I recommend doing this without all the confusion and complexity by returning to the premise of troubleshooting exactly one case at a time. You can choose which to begin with.

    Please put all your documentation of what is going on in this forum, thank you. The Github repo will change or disappear (it has already disappeared and then returned with different content in the course of just this discussion, so there is a previous link to it which is already out of date) and as a consequence make this discussion no use for anyone who has a similar issue to any of the many questions you are asking for information about.

    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 ?

    #1032390

    Paste the logs and VC contents in this forum, thank you. There are many other discussions here with big logs and they provide a way for searchers to get hits for specific errors and problems they are troubleshooting without my having to answer the same questions many times, as well as for me to be able to go back and find either bugs or points of confusion. When that is all hidden away in a repo they will eventually disappear as the repo changes or is removed, or cause the support request to occur in that repo, and won’t help anyone solve their problems where it is possible for them to follow on with a “I got the same log result but your fix isn’t affecting my case”. It’s a very important part of there being visibility for solutions.

    If you want to collapse the logs so that they aren’t as visually big, you can put spoiler tags around them:
    [spoiler]
    [/spoiler]
    this will make them possible to open and close so they don’t take up vertical space if it bothers you.

    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 ??

    Hi,

    That is happening because this code is a mixed example of an earlier grammar implementation and a later Rejecto implementation. Please change this:

    
    OEPocketsphinxController.sharedInstance().startListeningWithLanguageModel(atPath: lmPath, dictionaryAtPath: dictPath, acousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName), languageModelIsJSGF: true)
    

    to this:

    
    OEPocketsphinxController.sharedInstance().startListeningWithLanguageModel(atPath: lmPath, dictionaryAtPath: dictPath, acousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName), languageModelIsJSGF: false)
    

    and also please change this vowels option which looks like it must be left over from some previous round of experimentation and will harm accuracy:

    
    let err: Error! = lmGenerator.generateRejectingLanguageModel(from: words, withFilesNamed: fileName, withOptionalExclusions: nil, usingVowelsOnly: true, withWeight: 1.0, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))
    

    to this:

    
    let err: Error! = lmGenerator.generateRejectingLanguageModel(from: words, withFilesNamed: fileName, withOptionalExclusions: nil, usingVowelsOnly: false, withWeight: 1.0, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))

    If you want to show me more logs from this implementation, make sure to show me the now-changed code again as well.

    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 ??

    This:

    
    lmPath = lmGenerator.pathToSuccessfullyGeneratedGrammar(withRequestedName: fileName)
    

    needs to be:

    
    lmPath = lmGenerator.pathToSuccessfullyGeneratedLanguageModel(withRequestedName: fileName)

    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 ?)

    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).

    Regarding your Rejecto results: you can now pick whichever one of them is better and experiment with raising or reducing the value withWeight in this line (lowest possible value is 0.1 and largest possible value is 1.9):

    let err: Error! = lmGenerator.generateRejectingLanguageModel(from: words, withFilesNamed: fileName, withOptionalExclusions: nil, usingVowelsOnly: false, withWeight: 1.0, forAcousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName))

    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 ?)

    It represents the phone sound in Hochdeutsch which is represented by the IPA ə. This is getting outside of the things I support here but there should be enough info in that explanation for you to find sources outside of these forums to continue your investigation if you continue to have questions.

    The first thing in this RuleORama implementation to fix is again that this:

    
    OEPocketsphinxController.sharedInstance().startListeningWithLanguageModel(atPath: lmPath, dictionaryAtPath: dictPath, acousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName), languageModelIsJSGF: true)
    

    needs to be this:

    
    OEPocketsphinxController.sharedInstance().startListeningWithLanguageModel(atPath: lmPath, dictionaryAtPath: dictPath, acousticModelAtPath: OEAcousticModel.path(toModel: accusticModelName), languageModelIsJSGF: false)
    

    There may be other issues but let’s start there.

    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…)….

    #1032412

    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 ??

    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?

    #1032414
    Halle Winkler
    Politepix

    Yeah, that makes a certain amount of sense because this use case is very borderline for RuleORama – it isn’t usually great with a rule that has a single entry and the other elements of this which are pushing the limits of what is likely to work are probably making it worse. We can shelve the investigation of RuleORama now that we have seen a result from it.

    OK – let’s continue with Rejecto !

    I’ve recommended what is possible to tune for Rejecto, there is nothing else. If it isn’t doing well yet, this is likely to just be due to it being a different language. You can also tune vadThreshold but I recommended doing that at the start so I am assuming it is correct now.

    Have we ever seen a fully-working result from your original grammar implementation without a plugin since we fixed the grammar?

    #1032418
    iKK
    Participant

    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 ?

    #1032419
    Halle Winkler
    Politepix

    This is because there are multiple things about this which are a problem for ideal recognition with these tools: it has high uncertainty because it is a different language, and language models aren’t designed to work with a single word. I expect changing the weight to affect this outcome, but if it doesn’t, that is the answer on whether this approach will work.

    #1032420

    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.

    I think that if your original grammar implementation doesn’t raise any errors and is returning output that you can evaluate, we have explored everything that is within the realm of supportable troubleshooting here, so I am going to close this as answered because I think we have explored all of the topics which have come up here at substantial length and I think there should be enough for you to examine further outside of an ongoing troubleshooting process with me.

    If you have very specific questions later on (I mean, questions about a single aspect of a single implementation with a single acoustic model) it’s OK to start very focused new topics, just please create a fresh implementation you are comfortable sharing things about and you are sure doesn’t have accumulated code from different implementations, and remember to share the info in here without prompting from me so the questions don’t get closed, thanks and good luck!
