Active listening for assistant systems

1. A method comprising, by a computing system, the computing system comprising a client system and a companion device paired to the client system:

receiving, at the companion device from the client system, a first user input comprising a wake word associated with an assistant xbot;

setting the assistant xbot into a listening mode, wherein a continuous non-visual feedback is provided via the client system while the assistant xbot is in the listening mode;

receiving, at the companion device from the client system, a second user input comprising a user utterance while the assistant xbot is in the listening mode;

determining the second user input has ended based on a completion of the user utterance;

setting the assistant xbot into an inactive mode, wherein the non-visual feedback is discontinued via the client system while the assistant xbot is in the inactive mode; and

providing, via the companion device, a continuous visual feedback while the assistant xbot is in the listening mode.

2. The method of claim 1 , wherein the companion device is in a locked state when the wake word is received.

3. The method of claim 1 , wherein the assistant xbot is associated with a companion application executing on the companion device.

4. The method of claim 3 , wherein the companion application is executing as a background application on the companion device, and wherein the companion application is allowed by the companion device to access a computing capacity lower than a threshold capacity.

5. The method of claim 3 , further comprising:

executing the companion application as a foreground application in response to the continuous non-visual feedback; and

increasing the computing capacity the companion application is allowed to access a computing capacity greater than a threshold capacity.

6. The method of claim 1 , wherein the client system comprises one of a smart phone, smart glasses, augmented-reality (AR) glasses, a virtual-reality (VR) headset, or a smart watch.

7. The method of claim 1 , further comprising:

providing, via the client system in response to the first user input, an initial non-visual feedback before the continuous non-visual feedback, wherein the initial non-visual feedback indicates the initiation of the listening mode of the assistant xbot.

8. The method of claim 1 , wherein the continuous non-visual feedback is based on one or more of sound, vibration, or haptics.

9. The method of claim 1 , further comprising:

providing, via the client system, a continuous visual feedback while the assistant xbot is in the listening mode.

10. The method of claim 9 , wherein the continuous visual feedback is based on one or more of an icon associated with the assistant xbot, a visual indication of the listening mode, or light.

11. The method of claim 1 , wherein the continuous visual feedback is based on one or more of an icon associated with the assistant xbot, a visual indication of the listening mode, or light.

12. One or more computer-readable non-transitory non-volatile storage media embodying software that is operable when executed to:

receive, from a client system, a first user input comprising a wake word associated with an assistant xbot;

set the assistant xbot into a listening mode, wherein a continuous non-visual feedback is provided via the client system while the assistant xbot is in the listening mode;

receive, from the client system, a second user input comprising a user utterance while the assistant xbot is in the listening mode;

determine the second user input has ended based on a completion of the user utterance;

set the assistant xbot into an inactive mode, wherein the non-visual feedback is discontinued via the client system while the assistant xbot is in the inactive mode; and

provide, via a companion device paired to the client system, a continuous visual feedback while the assistant xbot is in the listening mode,

wherein the assistant xbot is associated with a companion application configured by the software.

13. The computer-readable non-transitory non-volatile storage media of claim 12 , wherein the client system comprises one or more of a smart phone, smart glasses, augmented-reality (AR) glasses, a virtual-reality (VR) headset, or a smart watch.

14. The computer-readable non-transitory non-volatile storage media of claim 12 , wherein the software is further operable when executed to: provide, via the client system in response to the first user input, an initial non-visual feedback before the continuous non-visual feedback, wherein the initial non-visual feedback indicates the initiation of the listening mode of the assistant xbot.

15. A system comprising: one or more processors; and a non-transitory non-volatile memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:

receive, from a client system, a first user input comprising a wake word associated with an assistant xbot;

set the assistant xbot into a listening mode, wherein a continuous non-visual feedback is provided via the client system while the assistant xbot is in the listening mode;

receive, from the client system, a second user input comprising a user utterance while the assistant xbot is in the listening mode;

determine the second user input has ended based on a completion of the user utterance;

set the assistant xbot into an inactive mode, wherein the non-visual feedback is discontinued via the client system while the assistant xbot is in the inactive mode; and

provide, via a companion device paired to the client system, a continuous visual feedback while the assistant xbot is in the listening mode,

wherein the assistant xbot is associated with a companion application configured by the instructions and executed by the processors.

16. The system of claim 15 , wherein the client system comprises one or more of a smart phone, smart glasses, augmented-reality (AR) glasses, a virtual-reality (VR) headset, or a smart watch.

17. The system of claim 15 , wherein the processors are further operable when executing the instructions to: provide, via the client system in response to the first user input, an initial non-visual feedback before the continuous non-visual feedback, wherein the initial non-visual feedback indicates the initiation of the listening mode of the assistant xbot.
