Disclosed herein are systems and methods for receiving a voice command and determining an appropriate action for the media playback system to execute based on user identification. The systems and methods receive a voice command for a media playback system, and determines whether the voice command was received from a registered user of the media playback system. In response to determining that the voice command was received from a registered user, the systems and methods configure an instruction for the media playback system based on content from the voice command and information in a user profile for the registered user.

A system for limiting vehicle operation is disclosed. The system may comprise one or more memory units for storing instructions and one or more processors configured to execute the instructions to perform operations. The operations may comprise determining that a key device is inside the vehicle; performing an authentication; setting the vehicle in a first vehicle mode; starting the vehicle based on the determination and the first authentication; and limiting vehicle operation based on the first vehicle mode.

Embodiments include techniques and objects related to a wearable audio device that includes a microphone to detect a plurality of sounds in an environment in which the wearable audio device is located. The wearable audio device further includes a non-acoustic sensor to detect that a user of the wearable audio device is speaking. The wearable audio device further includes one or more processors communicatively to alter, based on an identification by the non-acoustic sensor that the user of the wearable audio device is speaking, one or more of the plurality of sounds to generate a sound output. Other embodiments may be described or claimed.

Processing stacked data structures is provided. A system receives an input audio signal detected by a sensor of a local computing device, identifies an acoustic signature, and identifies an account corresponding to the signature. The system establishes a session and a profile stack data structure including a first profile layer having policies configured by a third-party device. The system pushes, to the profile stack data structure, a second profile layer retrieved from the account. The system parses the input audio signal to identify a request and a trigger keyword. The system generates, based on the trigger keyword and the second profile layer, a first action data structure compatible with the first profile layer. The system provides the first action data structure for execution. The system disassembles the profile stack data structure to remove the first profile layer or the second profile layer from the profile stack data structure.

A device and a method for detecting voice of a user of an intra-aural device. The intra-aural device has an in-ear microphone adapted to be in fluid communication with an outer-ear ear canal of the user occluded from an environment outside the ear. A signal provided by the in-ear microphone is obtained to determine an acquired voice indicator signal, and a voice produced by the user is detecting by comparing the acquired voice indicator signal with a corresponding threshold value, upon the acquired voice indicator signal being larger than the corresponding threshold value. Although the method also reduces any voice interference coming from a non-user, the results are improved when the non-user voice is captured from an outer-ear microphone of the intra-aural device.

The disclosure accurately authenticates a subject, regardless of which audio device is used for the in-ear acoustic authentication. A feature extraction unit (11) applies a test signal to an ear of a subject using an audio device, and upon receiving an acoustic signal from the subject, extracts, from the acoustic signal, a first feature relating to the system consisting of the audio device and the ear of the subject; a correction unit (12) corrects the first feature to a second feature that would result if a prescribed reference device were used instead of the audio device; and an authentication unit (13) authenticates the subject by comparing the second feature with a feature indicated by pre-registered authentication information.
