1. A headset device configured to support an audible interface, the headset device comprising:
a memory configured to store (i) a first audio signal, captured by an external microphone coupled to a housing of the headset device and facing away from a user wearing the headset device, wherein the first audio signal is representative of an environment external to the user wearing the headset device, and (ii) a second audio signal captured by an internal microphone coupled to the housing of the headset device and facing towards the user wearing the headset device; and
one or more processors configured to:
verify, based on the first audio signal and the second audio signal, that a self-voice signal of the user is detected that originated from the user wearing the headset device and not from an unauthorized entity that is not associated with the headset device, wherein the self-voice signal of the user includes a keyword based on processing one or more of the first audio signal and the second audio signal; and
obtain, based on the verification, additional audio signals representative of one or more audible commands included in the self-voice signal of the user.
 
17. The headset device of claim 1, wherein the headset device is a virtual reality device that includes the housing.
 
27. A headset device configured to support an audible interface, the headset device comprising:
means for storing (i) a first audio signal, captured by an external microphone coupled to a housing of the headset device and facing away from a user wearing the headset device, wherein the first audio signal is representative of an environment external to the user wearing the headset device, and (ii) a second audio signal captured by an internal microphone coupled to the housing of the headset device and facing towards the user wearing the headset device;
means for obtaining a first audio signal representative of an environment external to the user associated with the headset device;
means for obtaining a second audio signal sensed by a microphone coupled to a housing;
means for verifying, based on the first audio signal and the second audio signal, that a self-voice signal of the user is detected that originated from the user wearing the headset device and not from an unauthorized entity that is not associated with the headset device, wherein the self-voice signal of the user includes a keyword based on processing one or more of the first audio signal and the second audio signal; and
means for obtaining, based on the means for verifying, additional audio signals representative of one or more audible commands included in the self-voice signal of the user.
 
28. A non-transitory computer readable storage medium storing instructions that, when executed, cause one or mroe processors of a headset device to:
store (i) a first audio signal, captured by an external microphone coupled to a housing of the headset device and facing away from a user wearing the headset device, wherein the first audio signal is representative of an environment external to the user wearing the headset device, and (ii) a second audio signal captured by an internal microphone coupled to the housing of the headset device and facing towards the user wearing the headset device;
obtain a first audio signal representative of an environment external to the user associated with the headset device;
obtain a second audio signal sensed by a microphone coupled to a housing;
verify, based on the first audio signal and the second audio signal, that a self-voice signal of the user is detected that originated from the user wearing the headset device and not from an unauthorized entity that is not associated with the headset device, wherein the self-voice signal of the user includes a keyword based on processing one or more of the first audio signal and the second audio signal; and
obtain, based on the verification, additional audio signals representative of one or more audible commands included in the self-voice signal of the user.
