Hello,

I'm having a problem getting a Grammar object loaded successfully for
dictation.

I'm trying this on Server 2003 SP2 with UCMA 2.0 and WindowsXP SP3 with
Speech SDK 5.1 (both with VS2008, .Net 3.5), the exception messages are a
little different, but are basically the same. I'll post the details of each
one after my signature.

Ultimately I need the solution for the Server/UCMA system, but since
Microsoft.Speech and System.Speech are basically the same, I've been trying
to debug on both systems as I'm sure a solution for one will work on the
other.

Same code for both machines, the only difference is "using
Microsoft.Speech.Recognition;" vs. "using System.Speech.Recognition"

Code (I appologize for the line breaks):

this.engine = new
SpeechRecognitionEngine(Application.CurrentCulture);
this.engine.SpeechDetected += new
EventHandler<SpeechDetectedEventArgs>(engine_SpeechDetected);
this.engine.SpeechHypothesized += new
EventHandler<SpeechHypothesizedEventArgs>(engine_SpeechHypothesized);
this.engine.SpeechRecognitionRejected += new
EventHandler<SpeechRecognitionRejectedEventArgs>(engine_SpeechRecognitionRejected);
this.engine.SpeechRecognized += new
EventHandler<SpeechRecognizedEventArgs>(engine_SpeechRecognized);

GrammarBuilder dictaphoneGB = new GrammarBuilder();
dictaphoneGB.Culture = Application.CurrentCulture;

GrammarBuilder dictation = new GrammarBuilder();
dictation.Culture = Application.CurrentCulture;
dictation.AppendDictation();

dictaphoneGB.Append(new SemanticResultKey("StartDictation", new
SemanticResultValue("Start Dictation", true)));
dictaphoneGB.Append(new SemanticResultKey("dictationInput",
dictation));
dictaphoneGB.Append(new SemanticResultKey("EndDictation", new
SemanticResultValue("Stop Dictation", false)));

GrammarBuilder spellingGB = new GrammarBuilder();
spellingGB.Culture = Application.CurrentCulture;

GrammarBuilder spelling = new GrammarBuilder();
spelling.Culture = Application.CurrentCulture;
spelling.AppendDictation("spelling");

spellingGB.Append(new SemanticResultKey("StartSpelling", new
SemanticResultValue("Start Spelling", true)));
spellingGB.Append(new SemanticResultKey("spellingInput",
spelling));
spellingGB.Append(new SemanticResultKey("StopSpelling", new
SemanticResultValue("Stop Spelling", true)));

GrammarBuilder both = GrammarBuilder.Add((GrammarBuilder)new
SemanticResultKey("Dictation", dictaphoneGB),
(GrammarBuilder)new
SemanticResultKey("Spelling", spellingGB));

both.Culture = Application.CurrentCulture;

Grammar grammar = new Grammar(both);
grammar.Enabled = true;
grammar.Name = "Dictaphone and Spelling ";

this.engine.LoadGrammar(grammar); // Exception thrown here

/Code

This is based on the Microsoft example at:

http://msdn.microsoft.com/en-us/library/ms576566.aspx

and

http://msdn.microsoft.com/en-us/library/system.speech.recognition.grammarbuilder.debugshowphrases.aspx

Basically, what I need to do is get the functionality of the
DictationGrammar class in a "long handed way" out of the Grammar class, the
reason is because Microsoft.Speech.Recognition doesn't contain the
DictationGrammar class (this seems to be the only main difference between
the two namespaces/assemblies from a developer's point of view.)

If I can just get past that exception I should be good to go. And I will
settle for a grxml, a cfg, a runtime solution, anything that can dictate
speech in english using SAPI or UCMA. Because anything is better than where
I am now, trial and error over and over for 2 days.

I appreciate any guidance I can get, I've posted simpler problems on two
different Speech groups with little response. Also information on the web
is virtually nil for this topic.

So I ask one question...how good are you? :)

Thanks for reading folks,
Roger Frost
