If I remember correctly, the text-to-speech capabilies are 
implemented as an external, rather than being part of the engine. 
Given that, this is expected behavior... although it's 
counterintuitive that a "built-in command" isn't actually built in.

Either one seems sensible. The try structure is probably a bit more 
robust, since it will work even if you've built a standalone and 
forgotten to include the speech library.
