6. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising: determining whether a user that uttered a first audible command is the same as a user that uttered a second audible command; causing performance of an action associated with the second audible command at least partly in response to determining that the user that uttered the first audible command is the same as the user that uttered the second audible command; and refraining from causing performance of the action associated with the second audible command at least partly in response to determining that the user that uttered the first audible command is not the same as the user that uttered the second audible command.

One or more non-transitory computer-readable media as recited in claim 6 , wherein the determining is based at least in part on at least one of a Gaussian mixture model, a cMLLR matrix, or directionality relative to a device that captures one or more sounds associated with the first and second audible commands.
