Abstract

Methods and systems for controlling a portable computing device (“PCD”) are disclosed. In an example method, an always on processor (AoP) of a voice recognition module of the PCD receives a voice command. The AoP determines, without decoding the received voice command, that the received voice command corresponds to a previously determined keyword. The AoP retrieves context data associated with the previously determined keyword. The AoP acts on the voice command using the context data, including in some embodiments automatically triggering a fast dormancy of a communications channel.

Claims

1. A method for controlling a portable computing device (“

PCD”

), the method comprising;

heuristically determining a keyword by;

receiving a voice command with heuristic logic;

assigning a dormancy value to the voice command;

determining a user pattern for the voice command based on the dormancy value;

storing an analog packet and the context data associated with the keyword in a keyword cache;

receiving the voice command at an always on processor (AoP) of a voice recognition module of the PCD;

determining, with the AoP, without decoding the received voice command, that the received voice command corresponds to the previously determined and stored keyword;

retrieving, with the AoP, context data associated with the previously determined keyword; and

acting on the voice command, with the AoP, using the context data.

2. The method of claim 1, wherein:

acting on the voice command using the context data comprises establishing a communication channel from the PCD to a remote network; and

wherein the method further comprises

triggering, with the AoP, fast dormancy for the communication channel.

3. The method of claim 1, wherein the context data includes one or more of a time of day, a data request, a radio configuration, a last match timestamp, and a last match results.

4. The method of claim 1, wherein the previously determined keyword comprises an analog packet stored in a keyword cache in communication with the AoP.

5. The method of claim 4, wherein determining that the received voice command corresponds to the heuristically determined keyword comprises matching a waveform of the received voice command to the analog packet stored in the keyword cache.

6. The method of claim 1, wherein assigning the dormancy value to the voice command further comprises:

determining whether an additional command follows the received voice command; and

if no additional command follows the received voice command, then decrementing the dormancy value of the voice command.

7. A computer system controlling a portable computing device (“

PCD”

), the system comprising;

heuristic logic configured to heuristically determine a keyword by;

receiving a voice command with the heuristic logic;

assigning a dormancy value to the voice command;

determining a user pattern for the voice command based on the dormancy value; and

storing an analog packet and the context data associated with the keyword in a keyword cache;

a voice recognition (VR) module of the portable computing device, the VR module including an always on processor (AoP), the AoP configured to;

receive the voice command;

determine, without decoding, the received voice command that the received voice command corresponds to the previously determined keyword;

retrieve context data associated with the previously determined keyword; and

act on the voice command using the context data.

8. The computer system of claim 7, wherein:

acting on the voice command using the context data comprises establishing a communication channel from the PCD to a remote network; and

the AoP is further configured to trigger fast dormancy for the communication channel.

9. The computer system of claim 7, wherein the context data includes one or more of a time of day, a data request, a radio configuration, a last match timestamp, and a last match results.

10. The computer system of claim 7, wherein the VR module further comprises a keyword cache in communication with the AoP and wherein the previously determined keyword comprises an analog packet stored in the keyword cache.

11. The computer system of claim 10, wherein the AoP is furthered configured to determine that the received voice command corresponds to the previously determined keyword by matching a waveform of the received voice command to the analog packet stored in the keyword cache.

12. The computer system of claim 10, wherein the heuristic logic is further configured to assign the dormancy value to the voice command by:

determining whether an additional command follows the received voice command; and

if no additional command follows the received voice command, then decrementing the dormancy value of the voice command.

13. A computer program product comprising a non-transitory computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for controlling a portable computing device (“

PCD”

), said method comprising;

heuristically determining a keyword by;

receiving a voice command with heuristic logic;

assigning a dormancy value to the voice command;

determining a user pattern for the voice command based on the dormancy value;

storing an analog packet and the context data associated with the keyword in a keyword cache;

receiving the voice command at an always on processor (AoP) of a voice recognition module of the PCD;

determining, with the AoP, without decoding the received voice command, that the received voice command corresponds to the previously determined and stored keyword;

retrieving, with the AoP, context data associated with the previously determined keyword; and

acting on the voice command, with the AoP, using the context data.

14. The computer program product of claim 13, wherein:

acting on the voice command using the context data comprises establishing a communication channel from the PCD to a remote network; and

the method further comprises triggering, with the AoP, fast dormancy for the communication channel.

15. The computer program product of claim 13, wherein the context data includes one or more of a time of day, a data request, a radio configuration, a last match timestamp, and a last match results.

16. The computer program product of claim 13, wherein the previously determined keyword comprises an analog packet stored in a keyword cache in communication with the AoP.

17. The computer program product of claim 13, wherein determining that the received voice command corresponds to the heuristically determined keyword comprises matching a waveform of the received voice command to the analog packet stored in the keyword cache.

18. The computer program product of claim 13, wherein assigning the dormancy value to the voice command comprises:

determining whether an additional command follows the received voice command; and

if no additional command follows the received voice command, then decrementing the dormancy value of the voice command.
