If you intend on using the Text-To-Speech feature of the trainer, you will need to have 
the Microsoft Text-To-Speech engine installed, plus the SAPI 4.0 Runtime environment.  
Both are in this directory.

- Text-To-Speech Engine = tv_enua.exe
- SAPI 4.0		= spchapi.exe

If you would prefer to download them from Microsoft directly, here is the link:

*Note* - This is not a requirement to run the trainer.  Simply another method of feedback
for the user.
