JNI Exception with Java PXCMSpeechRecognition.StartRec

Alessio_Vinerbi — Mon, 05 Oct 2015 05:04:38 GMT

Hello to all,

I have a problem with speech recognition in Java.

I have successfully created a AudioSource and implementation of PXCMSpeechRecognition but when I try to call the function PXCMSpeechRecognition.StartRec, an exception occurs

java.lang.NoSuchMethodError: OnRecognized

If I try to add a function OnRecognized within my handler works but the callback is invoked only OnAlert

Can someone please help me ?

Hi,

Hi,

Can you give us details about your handler?

Did you get the prototypes like in this example ?

class MyHandler implements PXCMSpeechRecognition::Handler {

   public void OnRecognition(PXCMSpeechRecognition.RecognitionData data) {
       //process data
   }

};

Thanks Xavier,

Thanks Xavier,

Yes, but there is also OnAlert function.

My Handler is

class MyHandler implements PXCMSpeechRecognition::Handler
{
     public void OnRecognition(PXCMSpeechRecognition.RecognitionData data)
     {
     }

     public void OnAlert(PXCMSpeechRecognition.AlertData data) 
     {
     }
}


/////////////////// and i call StartRec

recognitionEngine.StartRect(source, new MyHandler());

When i call StartRec, i have an exception "java.lang.NoSuchMethodError: OnRecognized "

I had a look at the C ++ code, and actually he looks for a function called OnRecognized.

Indeed, if added, only for testing purposes, the function inside my handler:

public void OnRecognized(PXCMSpeechRecognition.RecognitionData data)
{
}

Works but i received only OnAlert callbacks....

Obviously the test I did was just to figure out what the problem was...

I hope I was clear and sorry for my English :)

Alessio

Thanks for the additional

Thanks for the additional info.

Indeed it seems there is a typo in the c++ wrapper for Java (C:\Program Files (x86)\Intel\RSSDK\framework\common\pxcclr.java\)

While we're fixing it, you can search and replace all occurences of "nRecognized" by "nRecognition" inside pxcmspeechrecognition.cpp, recompile the project and replace libpxcclr.*.dll for your project.

Thanks Xavier,

Alessio_Vinerbi — Tue, 06 Oct 2015 15:29:48 GMT

Thanks Xavier,

I loaded the project libpxcclr.jni_vs2010 and i have edited the pxcmspeechrecognition.cpp

I have change the line

AsyncCallback OnRecognizedCb(true, "OnRecognized", "(Lintel/rssdk/PXCMSpeechRecognition$RecognitionData;)V");

with

AsyncCallback OnRecognizedCb(true, "OnRecognition", "(Lintel/rssdk/PXCMSpeechRecognition$RecognitionData;)V");

And i have recompiled the DLL

Now, there isn't any exception on StartRec but the OnRecognition callback is never invoked.

I have seen that in StartRec function on cpp file use an SRHandler wrapper. This handler call invoke on OnRecognizedCb when an OnRecognition occurs from the recognition engine.

Alessio

Inside pxcmspeechrecognition

Xavier_H_Intel — Wed, 07 Oct 2015 07:29:09 GMT

Inside pxcmspeechrecognition.cpp, you need to change the other occurences of nRecognized too, more specifically to rename SRHandler::OnRecognized in SRHandler::OnRecognition

Alessio_Vinerbi — Wed, 07 Oct 2015 15:50:49 GMT

Xavier thanks for your patience.
I did all the substitutions and no exceptions occur when i call the StartRec

But now, when the in the moment to invoke the OnRecognition, it takes a crash of the virtual machine

I have recompiled the DLL with x64 in release mode.

Also, I give you another clue, when the ALERT_SPEECH_END alert occurs, application crash with JVM exception

Hello Xavier,

Alessio_Vinerbi — Sat, 10 Oct 2015 15:21:54 GMT

Hello Xavier,
I went ahead in the debug and I think I've found the cause.
Once made all substitutions (OnRecognized -> OnRecognition) the JVM crashed during the call to the callback OnRecognition

From my analysis it seems that the problem is the function Marshal :: initialize

When the function analyzes the fields of RecognitionData struct, tries to retrieve fieldID (fid) but the JNI GetFieldID fails when it encounters the field "Results" why can not encode the type ([Lintel/rssdk/PXCMSpeechRecognition$NBest;)

The function returns a FID equals 0 and print

intel/rssdk/PXCMSpeechRecognition$RecognitionData.GetFieldID(results,[Lintel/rssdk/PXCMSpeechRecognition$NBest;) not found

The crash happens during the actual copy Marshal :: why can not retrieve the array without a valid FID

In the Copy_s function of Marshal class at the end there is a switch :

jobject field=jni->GetObjectField(jdata,st->fields.fid);  // FID = 0
...
...
case 'L':
                    for (int j=0;j<st->fields.e_num;j++,offset+=st->fields.e_size) {
                        jobject element=jni->GetObjectArrayElement((jobjectArray)field,j);
                        Copy_s(jni,st->fields.element,element,offset, csize - st->fields.offset);
                    }
                }
...
...

the function GetObjectArrayElement crash with field named "Results" (Array of NBest[]) because st->fields.fid = 0 and field object is incorrect

I hope it can be of help my little analysis.

Anyway I will go on with the analysis

Alessio

Hello Xavier, I'm your

Alessio_Vinerbi — Mon, 12 Oct 2015 13:57:05 GMT

Hello Xavier, I'm your nightmare :)

I have some good news,

In the previous post I told you that, during initialization of the function copy_s, was not recognized the variable "scores" (NBest [4]) of RecognitionData struct

The reason is that the field names of NBest array differ between the Marshal :: Struct and structure RecognitionData

// Marshal::Field

static Marshal::Field PXCMSpeechRecognition_RecognitionData_fields[]={
	   {"timeStamp", offsetof(PXCSpeechRecognition::RecognitionData,timeStamp),"J"},
	   {"grammar", offsetof(PXCSpeechRecognition::RecognitionData,grammar),"I"},
	   {"duration", offsetof(PXCSpeechRecognition::RecognitionData,duration),"I"},
	   {"scores", offsetof(PXCSpeechRecognition::RecognitionData, scores), "[Lintel/rssdk/PXCMSpeechRecognition$NBest;", sizeof(PXCSpeechRecognition::NBest), 4, &PXCMSpeechRecognition_NBest},
	  {0},
};


// RecognitionData struct

    struct RecognitionData {
        pxcI64  timeStamp;               
        pxcUID  grammar;           
        pxcI32  duration;                
        NBest   results[NBEST_SIZE]; 
        pxcI32  reserved[16];         
    };

What I did was to realign the names using "scores"

Now I went over,

Now it is properly recognized the array NBest but inside the function copy_s fails to pull the single element from the array NBest

In Marshal.cpp : 155

case '[':
            {   
                jobject field=jni->GetObjectField(jdata,st->fields.fid);
				 
                switch (st->fields.sig[1]) {
                case 'I':
                case 'F':
                    Copy(jni,offset,st->fields.e_size,st->fields.e_num,(jarray)field);
                    break;
                case 'L':
                    for (int j=0;j<st->fields.e_num;j++,offset+=st->fields.e_size) {
                        jobject element=jni->GetObjectArrayElement((jobjectArray)field,j);
                        Copy_s(jni,st->fields.element,offset,element, csize - st->fields.offset);
                    }
                }
            }
            break;
        }

When he meets the array "scores" the loop executes but GetObjectArrayElement function returns a null value (0x0)
and the recursive call to copy_sfunction is not executed

Do you have any idea ?
Meanwhile, I try to solve it.

Thanks,

Alessio

Thanks Alessio and Xavier!

Thanks Alessio and Xavier!

Initializing the "scores" array with NBest() objects in class intel.rssdk.PXCMSpeechRecognition finally works for me.

    public static class RecognitionData {
        public long     timeStamp;	 /** The time stamp of the recognition, in 100ns. */
		public int      grammar;	 /** The grammar identifier for command and control, or zero for dictation. */
        public int      duration;	 /** The duration of the speech, in ms. */
		public NBest[] 	scores;      /** @size = NBEST_SIZE; The top-N recognition results for command and control. */        

        public RecognitionData()
        {
            scores = new NBest[NBEST_SIZE];   
            for(int i=0; i<scores.length; i++){
            	scores=new NBest();
            }
        }
    };

Hi All,

Dat_N_ — Mon, 10 Oct 2016 10:34:25 GMT

Hi All,

I got this error today and so lucky, I fixed it.

Error: intel/rssdk/PXCMSpeechRecognition$RecognitionData.GetFieldID(results,[Lintel/rssdk/PXCMSpeechRecognition$NBest;) not found

SDK: Build Number: 10.0.26.0396 (1.8GB)
Version: 2016 R2

Solution:

PXCMSpeechRecognition.java, change this

    public static class RecognitionData {
        public long     timeStamp;	 /** The time stamp of the recognition, in 100ns. */
		public int      grammar;	 /** The grammar identifier for command and control, or zero for dictation. */
        public int      duration;	 /** The duration of the speech, in ms. */
		public NBest[] 	scores;      /** @size = NBEST_SIZE; The top-N recognition results for command and control. */        

        public RecognitionData()
        {
            scores = new NBest[NBEST_SIZE];            
        }
    };

to this:

public static class RecognitionData {
    public long     timeStamp;   /** The time stamp of the recognition, in 100ns. */
    public int      grammar;     /** The grammar identifier for command and control, or zero for dictation. */
    public int      duration;    /** The duration of the speech, in ms. */
    public NBest[]  scores;      /** @size = NBEST_SIZE; The top-N recognition results for command and control. */       
    public RecognitionData()
    {
        scores = new NBest[NBEST_SIZE];  
        for(int i=0; i<scores.length; i++){
            scores=new NBest();
        }
    }
};
