Abstract

A system that allows a user to access a secured area by confirming location of the user near the secured area and receipt of an access word by the system. A user in possession of a mobile device may be detected at the entrance to a secured location. The system can select a question asking for a passcode corresponding to certain access to the secured location. The question can be spoken to a user through a loudspeaker at the secured location. The user's spoken response can be processed by the system, for example using keyword spotting, to determine if the proper access word is included. If it is, the system can grant access to the secured area.

First claim

What is claimed is:

1 . A computer-implemented method for allowing access to a property, the method comprising:
receiving, by a computing system, first audio data corresponding to a first utterance detected by at least one microphone of a device; determining, by the computing system, that the first audio data represents a first passphrase; based at least in part on the first audio data representing the first passphrase, causing, by the computing system, a first lock for a first access point of the property to unlock; receiving, by the computing system, second audio data corresponding to a second utterance detected by the at least one microphone of the device; determining, by the computing system, that the second audio data represents a second passphrase, the second passphrase being different than the first passphrase; and based at least in part on the second audio data representing the second passphrase, taking, by the computing system, at least one action to grant access to a second access point of the property, wherein the second access point is different from the first access point and the at least one action does not cause the first lock to unlock.

2 . The computer-implemented method of claim 1 , further comprising:
detecting a user presence proximate the device; determining third audio data corresponding to a message prompting utterance of a passphrase; and causing, based at least in part on the user presence proximate the device, audio corresponding to the third audio data to be output by at least one speaker of the device.

3 . The computer-implemented method of claim 2 , wherein:
detecting the user presence includes detecting a user input to the device.

4 . The computer-implemented method of claim 1 , wherein the at least one action includes causing a second lock for the second access point to unlock.

5 . The computer-implemented method of claim 4 , wherein the second access point includes a receptacle capable of receiving a package when the second lock is unlocked.

6 . The computer-implemented method of claim 5 , further comprising:
determining first data comprising instructions to unlock the receptacle, wherein taking the at least one action comprises causing the first data to be displayed on a screen of the device at the first access point.

7 . The computer-implemented method of claim 5 , further comprising:
determining first data comprising instructions to unlock the receptacle, wherein taking the at least one action comprises:
sending the first data to the device; and
causing the first data to be displayed on a screen of the device.

8 . The computer-implemented method of claim 1 , wherein the at least one action includes causing a garage door for the second access point to open.

9 . The computer-implemented method of claim 1 , wherein the at least one action includes outputting an access code that can be entered at the second access point to gain access to the second access point.

10 . The computer-implemented method of claim 1 , wherein the device is located at the property at least while the first utterance and the second utterance are detected by the at least one microphone.

11 . A computing system, comprising:
at least one processor; and at least one memory comprising instructions that, when executed by the at least one processor, cause the computing system to:
receive first audio data corresponding to a first utterance detected by at least one microphone of a device;
determine that the first audio data represents a first passphrase;
based at least in part on the first audio data representing the first passphrase, cause a first lock for a first access point of a property to unlock;
receive second audio data corresponding to a second utterance detected by the at least one microphone of the device;
determine that the second audio data represents a second passphrase, the second passphrase being different than the first passphrase; and
based at least in part on the second audio data representing the second passphrase, take at least one action to grant access to a second access point of the property, wherein the second access point is different from the first access point and the at least one action does not cause the first lock to unlock.

12 . The computing system of claim 11 , wherein the at least one memory comprises additional instructions that, when executed by the at least one processor, further cause the computing system to:
detect a user presence proximate the device; determine third audio data corresponding to a message prompting utterance of a passphrase; and cause, based at least in part on the user presence proximate the device, audio corresponding to the third audio data to be output by at least one speaker of the device.

13 . The computing system of claim 12 , wherein the at least one memory further comprises instructions that, when executed by the at least one processor, further cause the computing system to:
detect the user presence at least in part by detecting a user input corresponding to the device.

14 . The computing system of claim 11 , wherein the at least one action includes causing a second lock for the second access point to unlock.

15 . The computing system of claim 14 , wherein the second access point includes a receptacle capable of receiving a package when the second lock is unlocked.

16 . The computing system of claim 15 , wherein the at least one memory further comprises instructions that, when executed by the at least one processor, further cause the computing system to:
determine first data comprising instructions to unlock the receptacle; and take the at least one action at least in part by causing the first data to be displayed on a screen of the device at the first access point.

17 . The computing system of claim 15 , wherein the at least one memory further comprises instructions that, when executed by the at least one processor, further cause the computing system to:
determine first data comprising instructions to unlock the receptacle; and take the at least one action at least in part by causing the computing system to:
send the first data to the device; and
cause the first data to be displayed on a screen of the device.

18 . The computing system of claim 11 , wherein the at least one action includes causing a garage door for the second access point to open.

19 . The computing system of claim 11 , wherein the at least one action includes outputting an access code that can be entered at the second access point to gain access to the second access point.

20 . The computing system of claim 11 , wherein the device is located at the property.
