Windows Narrator
CSMMT makes use of Windows' TextToSpeech functionality to provide the user with additional feedback. Currently, CSMMT can read macro presses and most prompts and dialogs to the user. CSMMT also can make use of narration to read some dialogs.
Though some may like the narration feature, I understand that others may not and that it may become annoying at times. All narration in the program (with the exception of the Trial Splash) can be very easily disabled from the CSMMT Control Panel. Narration options can be found under the Config Menu from the CSMMT Control Panel.
Narration in CSMMT is broken up into two components, Help narration and macro narration.
Narrate Macros means that whenever you complete a macro combination on the keyboard it'll get narrated to you. For instance, "Macro Hit: Select Monitor 1" is one of the things that'd be narrated by this option. I'd personally recommend leaving at least macro narration enabled, as this is what started the entire idea of adding narration support to CSMMT in the first place. Whenever you're in full-screen applications there's no easy way to really know what you hit seeing as there's not always a GUI visible. If CSMMT wasn't working or if the macro support was just getting blocked, you'd have no idea without the ability for the program to tell you audibly what's going on. Still, the option exists to disable this if you wish.
Narrate Help is the narration of just about everything else in CSMMT. This is the option that makes CSMMT ultra-talkative. With Narrate Help enabled, practically everything you do in CSMMT will cause CSMMT to talk to you. With this option enabled CSMMT will read most Dialogs that it doesn't have any help for, and read help for Dialogs that it does have help for. After you've gotten the feel for CSMMT you can disable this option if you want. However, on the other hand if you configure macros to control everything in CSMMT then you won't be visiting the Control Panel much either way (and thus this option won't matter to you).
