Value does not fall within the expected range

Voices aren't working properly?

Value does not fall within the expected range

I'm using Cepstral David in an ASP.NET application via SpeechLib. I'm getting an error that states, "Value does not fall within the expected range."

Code: Select all
                SpMemoryStream speechStream = new SpMemoryStreamClass();
                SpVoice voice = new SpVoice();

                ISpeechObjectTokens tokens = voice.GetVoices("Name=Cepstral David");
                if (tokens.Count != 1)
                {
                    throw new Exception("Failed to find Cepstral David voice");
                }
                voice.Voice = tokens.Item(0);

                // Tell the voice events will be handled by calling WaitForNotifyEvent
                ISpEventSource eventSource = (ISpEventSource)voice;
                eventSource.SetNotifyWin32Event();
                voice.EventInterests = SpeechVoiceEvents.SVEWordBoundary | SpeechVoiceEvents.SVEEndInputStream | SpeechVoiceEvents.SVEBookmark;

                // Set the stream on the SpVoice object
                voice.AudioOutputStream = (ISpeechBaseStream)speechStream;

                // Speak
                voice.Speak(ttsMapper.TtsString, SpeechVoiceSpeakFlags.SVSFlagsAsync | SpeechVoiceSpeakFlags.SVSFIsXML);


The exception is being thrown from the call to Speak. It consistently fails on Windows Server 2003 when running in an ASP.NET application. My same application is working on Windows 7 (in IIS 7), and the same code also works fine in a desktop application on both Windows 2003 and Windows 7. I've tried the default voice built into Windows and it works fine in every scenario.

Any ideas? I found a 4 year old thread with someone else complaining about the same problem, but there was no resolution.

Yeah, this bug definitely seems to go back a ways. After an hour or so of hunting around through previous engineers emails, I am pretty confident that none of them ever took up the issue, much less provided a fix.

I will add it to the current bug list and welcome any feedback from the community if they have a work around.
