Abstract

Generally the present disclosure is directed to refrigerators and other appliances configured to provide dispensing in response to a voice command. One example appliance includes a sensor configured to provide an output signal indicating whether a receptacle is present in a dispensing area of the appliance. The appliance includes a microphone for receiving a human speech signal. The appliance includes a speech-to-text module configured to convert the human speech signal into textual information. The appliance includes a feature processing module configured to determine one or more requested actions based on the textual information. When the one or more requested actions comprise dispensing, the appliance is configured to perform the dispensing only when the output signal from the sensor indicates that the receptacle is present in the dispensing area.

Claims

1. An appliance comprising:

a dispensing system for dispensing liquid into a dispensing area;

a sensor configured to provide an output signal indicating whether a receptacle is present in the dispensing area;

one or more processors; and

one or more non-transitory computer readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations, the operations comprising;

obtaining the output signal from the sensor;

determining whether the receptacle is present in the dispensing area of the appliance based at least in part on the output signal;

when it is determined that the receptacle is present in the dispensing area, beginning to listen for voice commands;

receiving a human speech signal; and

determining one or more operations requested by the human speech signal.

2. The appliance of claim 1, wherein the sensor comprises a camera positioned so as to collect imagery depicting the dispensing area.

3. The appliance of claim 1, wherein the sensor comprises a pressure sensor positioned so that the receptacle present in the dispensing area rests upon the pressure sensor.

4. The appliance of claim 1, wherein the sensor comprises one or more ultrasound transducers positioned so as to direct ultrasonic waves into the dispensing area.

5. The appliance of claim 1, wherein the sensor comprises an infrared sensor.

6. The appliance of claim 1, wherein beginning to listen for voice commands comprises activating a microphone included in the appliance.

7. The appliance of claim 1, wherein beginning to listen for voice commands comprises actively analyzing received noise to identify the human speech signal.

8. The appliance of claim 1, wherein determining one or more operations requested by the human speech signal comprises:

converting the human speech signal to textual information; and

determining the one or more operations requested by the human speech signal based on the textual information.

9. The appliance of claim 1, wherein the operations further comprise:

identifying one of a plurality of enrolled users as a source of the human speech signal;

obtaining one or more preset preferences associated with the identified enrolled user and stored in a memory; and

performing the one or more operations in accordance with the one or more preset preferences.

10. The appliance of claim 1, wherein identifying one of the plurality of enrolled user comprises matching one or more biometrics of the human speech signal to one of a plurality of voice samples respectively associated with the plurality of enrolled users.

11. A method for operating an appliance, the method comprising:

obtaining an output signal from a sensor included in the appliance;

determining whether a receptacle is present in a dispensing area of the appliance based at least in part on the output signal;

when it is determined that the receptacle is present in the dispensing area, beginning to listen for voice commands;

receiving a human speech signal;

determining one or more operations requested by the human speech signal; and

performing the one or more operations.

12. The method of claim 11, wherein beginning to listen for voice commands comprises:

activating a microphone included in the appliance; and

analyzing audio signals received by the microphone to identify the human speech signal.

13. The method of claim 11, wherein the sensor comprises one or more of a camera, a pressure sensor, one or more ultrasound transducers, and an infrared sensor.

14. The method of claim 11, wherein determining one or more operations requested by the human speech signal comprises:

converting the human speech signal to textual information; and

determining the one or more operations requested by the human speech signal based on the textual information.

15. An appliance comprising:

a sensor configured to provide an output signal indicating whether a receptacle is present in a dispensing area of the appliance;

a microphone for receiving a human speech signal;

a speech-to-text module configured to convert the human speech signal into textual information; and

a feature processing module configured to determine one or more requested actions based on the textual information;

wherein, when the one or more requested actions comprise dispensing, the appliance is configured to perform the dispensing only when the output signal from the sensor indicates that the receptacle is present in the dispensing area.

16. The appliance of claim 15, wherein the sensor comprises one or more of a camera, a pressure sensor, one or more ultrasound transducers, and an infrared sensor.

17. The appliance of claim 15, further comprising a user identification module configured to identify one of a plurality of enrolled users based on an analysis of the human speech signal.

18. The appliance of claim 17, wherein the user identification module is configured to identify the one of the plurality of enrolled users by performing a matching routine with respect to the human speech signal and a plurality of voice samples respectively stored in the memory.

19. The appliance of claim 17, further comprising a user enrollment module configured to enroll a new user when the user identification module is unable to identify one of the plurality of enrolled users based on the analysis of the human speech signal.

20. The appliance of claim 19, wherein the user enrollment module is configured to enroll the new user by performing operations, the operations comprising:

receiving a voice sample from the new user;

receiving one or more preferences from the new user; and

associating the voice sample and the one or more preferences with the new user in the memory.
