Abstract

Systems and methods for managing wake-on-voice buffer quality based on system boot profiling. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include at least one logic circuit and at least one memory circuit coupled to the at least one logic circuit, the at least one memory including program instructions stored thereon that, upon execution by the at least one logic circuit, cause the IHS to: determine an expected time duration of a future wake event; receive a verbal command from a user, the verbal command configured to trigger the future wake event; capture the verbal command as an audio signal; adjust at least one of: a quality of the audio signal or a duration of the audio signal, where the adjustment is based, at least in part, upon the expected time duration; and store the adjusted audio signal in a fixed-size buffer.

Claims

1. An Information Handling System (IHS), comprising:

at least one logic circuit; and

at least one memory circuit coupled to the at least one logic circuit, the at least one memory including program instructions stored thereon that, upon execution by the at least one logic circuit, cause the IHS to;

determine an expected time duration of a future wake event;

receive a verbal command from a user, the verbal command configured to trigger the future wake event;

capture the verbal command as an audio signal;

adjust at least one of;

a quality of the audio signal or a duration of the audio signal, wherein the adjustment is based, at least in part, upon the expected time duration; and

store the adjusted audio signal in a fixed-size buffer.

2. The IHS of claim 1, wherein the at least one logic circuit includes a Digital Signal Processor (DSP).

3. The IHS of claim 2, wherein the future wake event includes a transition from a present power state to a subsequent power state, and wherein the subsequent power state consumes more power than the present power state.

4. The IHS of claim 3, wherein the verbal command includes a keyword.

5. The IHS of claim 4, wherein the verbal command includes an instruction following the keyword, the instruction configured to be executed by the IHS during the subsequent power state.

6. The IHS of claim 1, wherein to determine the expected time duration of the future wake event, the program instructions, upon execution by the at least one logic circuit, cause the IHS to create a profile of historical wake times between two or more different wake states.

7. The IHS of claim 6, wherein a wake time between two given wake states changes over time.

8. The method of claim 1, wherein to adjust the quality of the audio signal or the duration of the audio signal, the program instructions, upon execution by the at least one logic circuit, cause the IHS to change at least one of:

a codec of the audio signal, a compression of the audio signal, a sample rate of the audio signal, a bit depth of the audio signal, or a number of channels of the audio signal.

9. A method, comprising:

receiving an audio signal configured to trigger a wake event of an Information Handling System (IHS); and

adjusting a quality of the audio signal or a duration of the audio signal, based, at least in part, upon an expected time duration of the wake event, wherein the audio signal is stored in a memory having a fixed size.

10. The method of claim 9, wherein the wake event includes a transition from a present power state to a subsequent power state, and wherein the subsequent power state consumes more power than the present power state.

11. The method of claim 10, wherein the audio signal includes an instruction following the keyword, the instruction configured to be executed by the IHS during the subsequent power state.

12. The method of claim 9, further comprising creating a profile of historical wake times between two or more different wake states.

13. The method of claim 10, wherein the expected time duration of the wake event changes over time across different instances of the wake event.

14. The method of claim 10, wherein adjusting the quality of the audio signal further comprises changing a codec of the audio signal, a compression of the audio signal, a sample rate of the audio signal, a bit depth of the audio signal, or a number of channels of the audio signal.

15. A non-transitory computer-readable medium having program instructions stored thereon that, upon execution by an Information Handling System (IHS), cause the IHS to:

receive an audio signal configured to trigger a wake event of the IHS; and

adjust a quality of the audio signal or a duration of the audio signal, based, at least in part, upon an expected time duration of the wake event, wherein the audio signal is stored in a memory having a fixed size.

16. The non-transitory computer-readable medium of claim 15, wherein the wake event includes a transition from a present power state to a subsequent power state, and wherein the subsequent power state consumes more power than the present power state.

17. The non-transitory computer-readable medium of claim 15, wherein the audio signal includes an instruction following the keyword, the instruction configured to be executed by the IHS during the subsequent power state.

18. The non-transitory computer-readable medium of claim 15, wherein the program instructions, upon execution by the IHS, further cause the IHS to create a profile of historical wake times between two or more different wake states.

19. The non-transitory computer-readable medium of claim 15, wherein the expected time duration of the wake event changes over time across different instances of the wake event.

20. The non-transitory computer-readable medium of claim 15, wherein the program instructions, upon execution by the IHS, further cause the IHS to change a codec of the audio signal, a compression of the audio signal, a sample rate of the audio signal, a bit depth of the audio signal, or a number of channels of the audio signal.
