Abstract

An push-to-talk wireless communication device and method of facilitating a push-to-talk call are disclosed. The wireless communication device includes a voice recognition module that allows a user to establish and carry out a push-to-talk call through voice commands. The voice recognition module facilitates a push to talk call by establishing a push-to-talk call in response to a voice command. During the call, the voice recognition module identifies predetermined code words from the audio stream and manages the push-to-talk call functions accordingly.

Claims

1. A wireless communication device for facilitating a voice controlled push-to-talk call, comprising:

a push-to-talk module configured to establish a push-to-talk call, manage an active push-to-talk call, and terminate an established push-to-talk call; and

a voice recognition module configured to receive an audio segment, parse the audio segment to identify a voice command, analyze the voice command to determine a push-to-talk command, and instruct the push-to-talk module to execute the push-to-talk command.

2. The wireless communication device of claim 1, wherein the push-to-talk command is an initiate call push-to-talk command.

3. The wireless communication device of claim 1, wherein the voice recognition module is further configured to receive an audio segment during an active push-to-talk call, parse the audio segment to identify a voice command, analyze the voice command to determine a push-to-talk command and instruct the push-to-talk module to execute the push-to-talk command.

4. The wireless communication device of claim 3, wherein the push-to-talk command is a begin speaking push-to-talk command.

5. The wireless communication device of claim 3, wherein the push-to-talk command is an end speaking push-to-talk command.

6. The wireless communication device of claim 3, wherein the push-to-talk command is a set presence push-to-talk command.

7. The wireless communication device of claim 3, wherein the push-to-talk command is a set availability push-to-talk command.

8. The wireless communication device of claim 3, wherein the push-to-talk command is a terminate call push-to-talk command.

9. The wireless communication device of claim 3, wherein the voice recognition module is further configured to distinguish between a spoken voice command and a conversational use of the voice command.

10. A method for facilitating a voice controlled push-to-talk call on a wireless communication device, comprising:

initiating a voice recognition mode on a wireless communication device;

receiving an audio segment;

parsing the audio segment to determine a voice command;

identifying the voice command as a push-to-talk command; and

executing the push-to-talk command.

11. The method of claim 10, wherein the push-to-talk command is a set presence push-to-talk command and wherein the executing step comprises modifying a current push-to-talk presence setting for a user.

12. The method of claim 10, wherein the push-to-talk command is a set availability push-to-talk command and wherein the executing step comprises modifying a current push-to-talk availability setting for a user.

13. The method of claim 10, wherein the push-to-talk command is an initiate call push-to-talk command and wherein the executing step comprises establishing a push-to-talk call in response to the push-to-talk command.

14. The method of claim 13, further comprising:

receiving a second audio segment during the established push-to-talk call;

parsing the second audio segment to determine a second voice command;

identifying the second voice command as a second push-to-talk call command; and

executing the second push-to-talk command.

15. The method of claim 14, wherein the second push-to-talk command is a begin speaking push-to-talk command.

16. The method of claim 14, wherein the second push-to-talk command is an end speaking push-to-talk command.

17. The method of claim 14, wherein the parsing step further comprises distinguishing between a spoken voice command and a conversational use of the spoken voice command in the second audio segment.

18. A computer readable medium having stored thereon one or more sequences of instructions for causing one or more microprocessors to perform the steps for facilitating a voice controlled push-to-talk call on a wireless communication device, the steps comprising:

initiating a voice recognition mode on a wireless communication device;

receiving an audio segment;

parsing the audio segment to determine a voice command;

identifying the voice command as a push-to-talk command; and

executing the push-to-talk command.

19. The computer readable medium of claim 18, wherein the push-to-talk command is a set presence push-to-talk command and wherein the executing step comprises modifying a current push-to-talk presence setting for a user.

20. The computer readable medium of claim 18, wherein the push-to-talk command is a set availability push-to-talk command and wherein the executing step comprises modifying a current push-to-talk availability setting for a user.

21. The computer readable medium of claim 18, wherein the push-to-talk command is an initiate call push-to-talk command and wherein the executing step comprises establishing a push-to-talk call in response to the push-to-talk command.

22. The computer readable medium of claim 21, wherein the steps further comprise:

receiving a second audio segment during the established push-to-talk call;

parsing the second audio segment to determine a second voice command;

identifying the second voice command as a second push-to-talk call command; and

executing the second push-to-talk command.

23. The computer readable medium of claim 22, wherein the second push-to-talk command is a begin speaking push-to-talk command.

24. The computer readable medium of claim 22, wherein the second push-to-talk command is an end speaking push-to-talk command.

25. The computer readable medium of claim 22, wherein the parsing step further comprises distinguishing between a spoken voice command and a conversational use of the spoken voice command in the second audio segment.
