When using an L&H TTS engine, my VB app crashes on TextToSpeech invocations. I have noticed that I had a "On error resume next statement" before the ChantTTS.TextToSpeech command. When I removed it, I noticed Visual Basic gives the error message "Out of stack space" when trying to speak. After you click on ok, it causes a page fault in KERNEL32. I guess if the error is ignored by the "On error resume next statement" this causes OLEAUT32.DLL to crash somehow.
It is possible with the L&H TTS engine modes that they return a null ttsMouth structures. This problem only occurs if you are using TextToSpeechVisual calllback.
Fixed in SpeechKit 2.1.1.
