Multi-modal interaction with intelligent assistants in voice command devices
A method comprising detecting an activation of an intelligent assistant on an electronic device, waking up the intelligent assistant from a sleep mode in response to the activation, and determining an amount of vocabulary the intelligent assistant acts upon during a listening mode based on a type of the activation.
1. A method of operating an electronic device comprising a display, a microphone, a speaker, and at least one sensor, the method comprising:
based on a first occurrence of a first event, providing a first feedback via at least one of the display or the speaker, the first event comprising identifying a wake word from a first speech signal obtained via the microphone;
generating a first timeout based on no speech signal being obtained via the microphone within a first time duration after providing the first feedback;
based on a first occurrence of a second event, providing a second feedback via at least one of the display or the speaker, the second event comprising detecting, via the at least one sensor, an external object within a proximity of the electronic device, and the second feedback being different from the first feedback; and
generating a second timeout based on no speech signal being obtained via the microphone within a second time duration after providing the second feedback,
wherein the method further comprising:
generating a third timeout based on no voice command being identified from a second speech signal obtained via the microphone within a third time duration after a second occurrence of the first event; and
generating a fourth timeout based on no voice command being identified from a third speech signal obtained via the microphone within a fourth time duration after a second occurrence of the second event.
2. The method of claim 1 , wherein the first feedback comprises a feedback based on at least one of a sound, provided via the speaker, and or a feedback based on a visual indication, provided via the display, and
wherein the second feedback comprises a feedback based on a visual indication, provided via the display.
3. The method of claim 1 , wherein the first time duration is different from the third time duration, and the second time duration is different from the fourth time duration.
4. The method of claim 3 , wherein the first time duration is longer than the second time duration, and the third time duration is longer than the fourth time duration.
5. The method of claim 1 , further comprising: providing, based on the generating the first timeout, a visual indication indicating a transition to a sleep mode.
6. The method of claim 1 , further comprising: providing, based on the generating the second timeout, a visual indication indicating a transition to a sleep mode.
7. The method of claim 1 , further comprising: based on the second speech signal being obtained via the microphone and prior to the generating the third timeout, displaying, on the display, a text phrase indicating a transition to a listening mode.
8. The method of claim 1 , further comprising: based on the third speech signal being obtained via the microphone and prior to the generating the fourth timeout, displaying, on the display, a text phrase indicating a transition to a listening mode.
9. The method of claim 1 , wherein the generating the third timeout comprises providing a speech response, via the speaker, indicating no voice command being identified from the second speech signal.
10. The method of claim 1 , wherein the generating the fourth timeout comprises providing a visual feedback, via the display, indicating no voice command being identified from the third speech signal.
11. An electronic device comprising:
a display;
a microphone;
a speaker;
at least one sensor; and
at least one processor coupled to the display, the microphone, the speaker, and the at least one sensor, and configured to:
based on a first occurrence of a first event, provide a first feedback via at least one of the display or the speaker, the first event comprising identifying a wake word from a first speech signal obtained via the microphone;
generate a first timeout based on no speech signal being obtained via the microphone within a first time duration after providing the first feedback;
based on a first occurrence of a second event, provide a second feedback via at least one of the display or the speaker, the second event comprising detecting, via the at least one sensor, an external object within a proximity of the electronic device, and the second feedback being different from the first feedback; and
generate a second timeout based on no speech signal being obtained via the microphone within a second time duration after providing the second feedback,
wherein the at least one processor is further configured to:
generate a third timeout based on no voice command being identified from a second speech signal obtained via the microphone within a third time duration after a second occurrence of the first event; and
generate a fourth timeout based on no voice command being identified from a third speech signal obtained via the microphone within a fourth time duration after a second occurrence of the second event.
12. The electronic device of claim 11 , wherein the first feedback comprises a feedback based on a sound, provided via the speaker, or a feedback based on a visual indication, provided via the display.
13. The electronic device of claim 11 , wherein the first time duration is different from the third time duration, and the second time duration is different from the fourth time duration.
14. The electronic device of claim 13 , wherein the first time duration is longer than the second time duration, and the third time duration is longer than the fourth time duration.
15. The electronic device of claim 11 , wherein the at least one processor is further configured to: provide, based on the generating the first timeout, a visual indication indicating a transition to a sleep mode.
16. The electronic device of claim 11 , wherein the at least one processor is further configured to: provide, based on the generating the second timeout, a visual indication indicating a transition to a sleep mode.
17. The electronic device of claim 11 , wherein the at least one processor is further configured to: based on the second speech signal being obtained via the microphone and prior to the generating the third timeout, control the display to display a text phrase indicating a transition to a listening mode.
18. The electronic device of claim 11 , wherein the at least one processor is further configured to: based on the third speech signal being obtained via the microphone and prior to the generating the fourth timeout, control the display to display a text phrase indicating a transition to a listening mode.
19. The electronic device of claim 11 , wherein the at least one processor is further configured to, in generating the third timeout, provide a speech response, via the speaker, indicating no voice command being identified from the second speech signal.
20. The electronic device of claim 11 , wherein the at least one processor is further configured to, in generating the fourth timeout, provide a visual feedback, via the display, indicating no voice command being identified from the third speech signal.
