Application output to Synthesizer.Speak - System.Speech.dll - Non Microsoft Voices

Question

My problem is that my understanding of the reason for this question is alluding to me, not to the workaround. I wonder if anyone can explain why I am getting this problem?

I populate a ComboBox with local computers installed:

private void getSystemVoices()
{
foreach (InstalledVoice voiceName in synthesizer.GetInstalledVoices())
{
this.voiceComboBox.Items.Add(voiceName.VoiceInfo.Name);
}
}

My Application runs on an x86 processor, so all installed voices are populated in this ComboBox. I have some Acapela Voices Installed, I believe that they are compatible with SAPI 5.1. Lucy, Heather and Ryan.

I am testing this code for using tones:

// Initialize a new instance of the SpeechSynthesizer...
SpeechSynthesizer synthesizer = new SpeechSynthesizer();

// Config the audio output... 
synthesizer.SetOutputToDefaultAudioDevice();

// Initialize a new instance of the PromptBuilder...
PromptBuilder promptBuilder = new PromptBuilder();

// Config SSML...
promptBuilder.AppendSsmlMarkup("<voice xml:lang=\"en-AU\">");
promptBuilder.StartVoice(this.voiceComboBox.SelectedItem.ToString());
promptBuilder.AppendText("The quick brown fox jumps over the lazy dog.");
promptBuilder.EndVoice();
promptBuilder.AppendSsmlMarkup("</voice>");

// Speak the prompt...
synthesizer.Speak(promptBuilder);
