Accepting voice commands based on user identity

摘要

Techniques for determining when to perform an action associated with a voice command and when to disregard the voice command. In some instances, the techniques reference an identity of a user that utters a command when making this determination. For instance, if a first user awakens a device or initially begins providing voice commands to the device, the device or another computing device may perform actions associated with subsequent voice commands uttered by the same user, while disregarding voice commands from other users. That is, because the device is engaging in a dialog with a first user, the device may refrain from engaging in a dialog with a different user. Additionally or alternatively, the device may begin a new dialog with the different user, either upon identifying the command of the other user or upon finishing the dialog with the first user.

主权项

1. One or more computing devices comprising:
one or more processors; one or more computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising: receiving a first audio signal generated based on a first sound captured within an environment; identifying first speech from the first audio signal, the first speech including a wake word; receiving a second audio signal generated based on a second sound captured within the environment; determining that the second audio signal includes second speech; determining whether a user that spoke the first speech is the same as a user that spoke the second speech; causing performance of an action associated with the second speech at least partly in response to determining that the user that spoke the first speech is the same as the user that spoke the second speech; and refraining from causing performance of the action associated with the second speech at least partly in response to determining that the user that spoke the first speech is not the same as the user that spoke the second speech.
