Abstract

Methods and apparatus are provided for automatic un-muting of a telephone call. A muted telephone of a user is automatically un-muted during a telephone call by evaluating whether the user is facing the telephone while speaking during the telephone call. The telephone can optionally be automatically muted when the user stops speaking and is not facing the telephone. A telephone call of a user can also be processed by evaluating whether the user is facing the telephone while speaking during the telephone call; and providing a message to the user indicating that the telephone is muted if the user is facing the telephone while speaking during the telephone call.

First claim

What is claimed is:

1. A method for automatically un-muting a muted telephone of a user during a telephone call, comprising:
evaluating, using at least one processing device, whether said user is facing said telephone while speaking during said telephone call based on processing of speech and images of said user, wherein said step of evaluating whether said user is facing said telephone further comprises evaluating sound waves of said user by determining whether said sound waves reach a plurality of microphones associated with said telephone at substantially the same time; and
automatically un-muting said telephone, using at least one processing device, if said user is facing said telephone while speaking during said telephone call.

2. The method of claim 1 , wherein said step of evaluating whether said user is facing said telephone further comprises evaluating a facial pose of said user.

3. The method of claim 2 , wherein said step of evaluating said facial pose of said user further comprises the step of determining whether a nose of said user is substantially visible as a front-facing view in images generated by a camera associated with said telephone.

4. The method of claim 2 , wherein said step of evaluating said facial pose of said user further comprises the step of determining whether both eyes of said user are substantially visible in images generated by a camera associated with said telephone.

5. The method of claim 2 , wherein said step of evaluating said facial pose of said user further comprises the step of assigning a score to said facial pose of said user indicating a degree to which said user is facing said telephone.

6. The method of claim 1 , further comprising the step of automatically muting said telephone when said user stops speaking and is not facing said telephone.

7. The method of claim 1 , wherein said step of automatically un-muting said telephone is disabled if said telephone is in a hard-mute mode.

8. A method for processing a telephone call by a user, comprising:
evaluating, using at least one processing device, whether said user is facing said telephone while speaking during said telephone call based on processing of speech and images of said user, wherein said step of evaluating whether said user is facing said telephone further comprises evaluating sound waves of said user by determining whether said sound waves reach a plurality of microphones associated with said telephone at substantially the same time; and
providing a message to said user, using at least one processing device, indicating that said telephone is muted if said user is facing said telephone while speaking during said telephone call.

9. An apparatus for automatically un-muting a muted telephone of a user during a telephone call, the apparatus comprising:
a memory; and
at least one hardware device, coupled to the memory, operative to:
evaluate, using at least one processing device, whether said user is facing said telephone while speaking during said telephone call based on processing of speech and images of said user, wherein said step of evaluating whether said user is facing said telephone further comprises evaluating sound waves of said user by determining whether said sound waves reach a plurality of microphones associated with said telephone at substantially the same time; and
automatically un-mute said telephone, using at least one processing device, if said user is facing said telephone while speaking during said telephone call.

10. The apparatus of claim 9 , wherein said evaluation of whether said user is facing said telephone further comprises evaluating a facial pose of said user.

11. The apparatus of claim 10 , wherein said evaluation of said facial pose of said user determines whether a nose of said user is substantially visible as a front-facing view in images generated by a camera associated with said telephone.

12. The apparatus of claim 10 , wherein said evaluation of said facial pose of said user determines whether both eyes of said user are substantially visible in images generated by a camera associated with said telephone.

13. The apparatus of claim 10 , wherein said evaluation of said facial pose of said user assigns a score to said facial pose of said user indicating a degree to which said user is facing said telephone.

14. The apparatus of claim 9 , wherein said at least one hardware device is further configured to automatically mute said telephone when said user stops speaking and is not facing said telephone.

15. The apparatus of claim 9 , wherein said automatic un-muting of said telephone is disabled if said telephone is in a hard-mute mode.

16. An article of manufacture for automatically un-muting a muted telephone of a user during a telephone call, comprising a tangible machine readable recordable medium containing one or more programs which when executed implement the steps of:
evaluating, using at least one processing device, whether said user is facing said telephone while speaking during said telephone call based on processing of speech and images of said user, wherein said step of evaluating whether said user is facing said telephone further comprises evaluating sound waves of said user by determining whether said sound waves reach a plurality of microphones associated with said telephone at substantially the same time; and
automatically un-muting said telephone, using at least one processing device, if said user is facing said telephone while speaking during said telephone call.

17. The article of manufacture of claim 16 , wherein said step of evaluating whether said user is facing said telephone further comprises evaluating a facial pose of said user.

18. The article of manufacture of claim 17 , wherein said step of evaluating said facial pose of said user further comprises the step of assigning a score to said facial pose of said user indicating a degree to which said user is facing said telephone.

19. The article of manufacture of claim 16 , further comprising the step of automatically muting said telephone when said user stops speaking and is not facing said telephone.

20. The article of manufacture of claim 16 , wherein said step of automatically un-muting said telephone is disabled if said telephone is in a hard-mute mode.
