Default Custom rom with custom voice control

Does anyone know a good custom rom where I can use my own phrase to turn the display on? the current one is set to "Hi Galaxy" with no other way to change that phrase. Also, is there a function where I can replace S voice with Google voice control in a custom ROM? Currently I am using S for Switch Voice and its good, but doesn't work all the time.

also, this is a more general question. If I have a Canadian locked phone (Rogers), do I still use the ROMS for at&t or can I go with the Samsung note 3 rom page? i was using att for my S3 and i9000
