Voice recognition/identification

I've been searching around for some time now, and all i can find about voice recognition is voice to text typing. Does anyone k开发者_运维知识库now if there's a way to recognize a users voice to trigger a command, that would'nt be triggered if someone else repeated the same command.

Any directions or useful keywords about how/where to find info on this subject is appreciated.

EDIT: voice prints lead to MARF(Modular Audio Recognition Framework).
