Claim 8:
9. A device comprising:
at least one processor; and
memory storing instructions that, when executed, cause the at least one processor of the device to:
monitor an audio input for an occurrence of a trigger phrase that is spoken by a user of the device while the device is in a low power mode;
in response to detecting the occurrence of the trigger phrase:
wake the device from the low power mode; and
buffer the audio input while the device wakes up from the low power mode; and
in response to the device waking up from the low power mode, monitor the buffered audio input for an occurrence of a command phrase that is spoken by the user, wherein the command phrase corresponds to a call command and a call parameter;

in response to detecting the occurrence of the command phrase:
select a set of target contacts associated with the device based on respective voice validation scores and respective contact confidence scores, wherein the respective voice validation scores indicate a corresponding likelihood that the call parameter is associated with a corresponding target contact, included in the set of target contacts, and wherein the respective contact confidence scores indicate a corresponding additional likelihood that a user context associated with the user for the call action being directed to the corresponding target contact, included in the set of target contacts; and
in response determining that a given voice validation score, of the respective voice validation scores, for a priority contact included in the set of target contacts, meets a validation threshold and in response to determining that a given contact confidence score, of the respective contact confidence scores, for the priority contact, included in the set of target contacts, meets a confidence threshold:
automatically place a call to the priority contact.
