onRecognition of PXCMSpeechRecognition.Handler dose not fire in WCF Service when hosted in IIS

[Priyank_T_]

 onRecognition of PXCMSpeechRecognition.Handler dose not fire in WCF Service when hosted in IIS. The handler is called in development environment but it is not called when deployed in IIS.

See Below Code.

        bool HasSpeechRecognised = false;
        string SpeechText = string.Empty;

       public string GetText(Byte[] value)

        {
            PXCMSession session = PXCMSession.CreateInstance();

            // session is a PXCMSession instance.
         
            var FileName = @"D:\Test\ServiceInput.wav";
            System.IO.File.WriteAllBytes(FileName, value);

            PXCMAudioSource source = session.CreateAudioSource();

            // Set the audio fie
            PXCMAudioSource.DeviceInfo dinfo = new PXCMAudioSource.DeviceInfo();
            dinfo.did = FileName;

            // Set the active device
            source.SetDevice(dinfo);

            PXCMSpeechRecognition sr;

            session.CreateImpl<PXCMSpeechRecognition>(out sr);

            PXCMSpeechRecognition.ProfileInfo pinfo;
            sr.QueryProfile(0, out pinfo);
            sr.SetProfile(pinfo);
            // Set handler
            PXCMSpeechRecognition.Handler handler = new PXCMSpeechRecognition.Handler();
            handler.onRecognition = OnRecognition;
            // Start recognition

            var Status = sr.StartRec(source, handler);

            while (!HasSpeechRecognised)
            {
              
            }
         
            sr.StopRec();
            sr.Dispose();

            session.Dispose();                    

            return SpeechText;
        }

  private void OnRecognition(PXCMSpeechRecognition.RecognitionData data)
        {
          
            HasSpeechRecognised = true;
            // Process Recognition Data
            var d = data;
            if (d.scores.Length >= 1)
            {
                SpeechText = d.scores[0].sentence;
            }
            else
            {
                SpeechText = "Invalid Audio";
            }           

        }
