Speech Recognition Utility CreateLexicon

Hello again,

I'm trying to write an application that uses the speech recognition API. 
When I call CreateLexicon I get an ErrorCode -14 (Object in use by 
another application). But there is no other application running in the 
emulator. How can I fix the problem? Here is the part of my source that 
is relevant:

TInt				errCode;
TUint16				buffer[1024];
TPtr				ptr( buffer, 0, 1024 );
TPtrC				errText;
RArray<TLexiconID>	lexIds;
CAknInformationNote	*informationNote  = new ( ELeave )
CAknInformationNote;
CErrorUI			*errBox = CErrorUI::NewL();

iEikonEnv ->InfoMsg( _L("Speech") );

speech = CSpeechRecognitionUtility::NewL( speechObserver, KUidtest );
if( speech )
{
     errCode = speech->GetAllLexiconIDs( lexIds );
     if( errCode != KErrNone )
         errText.Set( _L("Lex Error") );
     if( errCode == KErrNone )
     {
         if( lexIds.Count() == 0 )
         {
             errCode = speech->CreateLexicon( lexiconID );
             if( errCode == KErrNone )
             {
                 errCode = speech->CommitChanges();
                 if( errCode != KErrNone )
                     errText.Set( _L("Changes not saved") );
             }
             else
                 errText.Set( _L("Lexicon not created") );
         }
         else
             lexiconID = lexIds[0];
     }
     if( errCode == KErrNone )
     {
         ptr.Format( _L("%d lexicons"), lexIds.Count() );
         informationNote->ExecuteLD( ptr );
     }

     else

     {

         errBox->ShowGlobalErrorQueryL( errCode );
         ptr.Format( _L("%d: %s"), errCode, errText.Ptr() );
         informationNote->ExecuteLD( ptr );
     }
}

else

     informationNote->ExecuteLD( _L("Speech not loaded") );

Thanks in advance

Martin
