How to disable Samsung Text-to-Speech and delete language files

Hi,

I use Google's TTS engine, so I thought I could disable Samsung's and get rid of the language files it has downloaded.

Sadly, I can't seem to find the application on the list of installed applications under Application Manager. In fact, I don't know what it's called.

Also, I don't know the location of the language files.

Any help would be appreciated.
Thank you.
