Identification using audio signatures and additional characteristics
First Claim
1. An apparatus comprising:
- a microphone;
a processor; and
computer-readable media storing computer-executable instructions that, when executed on the processor, cause the processor to perform acts comprising;
generating, by the microphone, an audio signal based on audio uttered by a user and captured by the microphone;
comparing a signature of the audio signal to a previously stored signature that is associated with a particular user;
calculating a similarity between the signature of the audio signal and the previously stored signature based at least in part on the comparing;
at least partly in response to the similarity being greater than a threshold, identifying the user that uttered the audio as the particular user; and
at least partly in response to the similarity being less than the threshold;
identifying a command associated with the audio signal;
determining a characteristic associated with the command; and
attempting to identify the user that uttered the audio based at least in part on the signature of the audio signal and on the determined characteristic.

Abstract
Techniques for identifying users that issue audio commands based on signatures associated with the commands and additional characteristics associated with the commands. For instance, a device that includes a microphone may capture audio uttered by a user. The device, or another device, may then compare a signature associated with a generated audio signal to audio signatures associated with known users. For instance, the device may have access to multiple audio signatures, each of which is unique to a respective user that has previously interacted with the device or with another device. The device may then use this comparison to help identify the user that uttered the audio. In addition, however, the device may utilize a characteristic other than the audio signature. Using both the comparison of the audio signature to the previously received signatures along with the additional characteristic(s), the device may make a presumed identification of the user.

23. Non-transitory computer-readable media storing computer-executable instructions that, when executed on a processor, cause the processor to perform acts comprising:
-
receiving a generated audio signal that has been generated by a microphone based on audio captured by the microphone; comparing a signature of the generated audio signal to a previously stored audio signature associated with a particular user; calculating a similarity between the signature of the generated audio signal and the previously stored audio signature; at least partly in response to the similarity being greater than a threshold, identifying a user that uttered audio associated with the generated audio signal as the particular user; and at least partly in response to the similarity being less than the threshold; identifying a command associated with the generated audio signal; determining a characteristic associated with the command; and attempting to identify the user that uttered the audio associated with the audio signal based at least in part on the signature of the generated audio signal and on the determined characteristic. - View Dependent Claims (24, 25, 26, 27, 28)
