17. An apparatus comprising:
one or more processors; and
memory storing processor-executable instructions that, when executed by the one or more processors, cause the apparatus to:
receive audio content;
based on one or more voice characteristics associated with the audio content that indicate that the audio content is associated with an authorized user, determine to use a low wake word threshold for processing the audio content; and
based on a determination, using the low wake word threshold, that at least a portion of the audio content corresponds to a wake word or phrase, cause execution of one or more operational commands associated with the audio content.
 
23. An apparatus comprising:
one or more processors; and
memory storing processor-executable instructions that, when executed by the one or more processors, cause the apparatus to:
receive audio content;
based on one or more voice characteristics associated with the audio content that indicate that the audio content is not associated with one or more authorized users, determine to use a high wake word threshold for processing the audio content; and
based on a determination, using the high wake word threshold, that at least a portion of the audio content corresponds to a wake word or phrase, cause execution of one or more operational commands associated with the audio content.
