Abstract

Methods and apparatus to manage conference calls are described. An example method includes classifying participants of the conference call in a hierarchy according to respective priority values; detecting an attempt of a participants to speak at a same time; detecting which one of the participants has a lower priority ranking; blocking an audio signal of the one of the participants having the lower priority ranking; placing an identifier associated with the blocked one of the participants in a queue; organizing the queue according to a behavior-based policy by comparing an utterance of a current speaker to a keyword associated with the conference call to determine a relevancy of the utterance; and increasing a point total associated with the current speaker in response to determining that the utterance is substantially relevant, and decreasing the point total associated with the current speaker in response to determining that the utterance is substantially irrelevant.

Claims

1. A method of managing a conference call, comprising:

classifying participants of the conference call in a hierarchy according to respective priority values;

detecting an attempt of a first participant and a second participant to speak at substantially a same time;

detecting which one of the first and second participants has a lower priority ranking;

blocking an audio signal of the one of the first participant and the second participant having the lower priority ranking;

placing an identifier associated with the blocked one of the first and second participants in a queue;

organizing the queue according to a behavior-based policy, wherein organizing the queue according to the behavior-based policy comprises comparing an utterance of a current speaker to a keyword associated with the conference call to determine a relevancy of the utterance; and

increasing a first point total associated with the current speaker in response to determining that the utterance is substantially relevant, and decreasing the first point total associated with the current speaker in response to determining that the utterance is substantially irrelevant.

2. A method as defined in claim 1, further comprising enabling the audio signal of a second one of the first and second participants when the one of the first and second participants is finished speaking and when the second one of the first and second participant is in a first position of the queue.

3. A method as defined in claim 1, further comprising displaying an indication of blockage to the one of the first and second participants.

4. A method as defined in claim 1, further comprising organizing the queue according to the priority values of blocked participants.

5. A method as defined in claim 1, further comprising organizing the queue according to a time at which attempted interruptions occur.

6. A method as defined in claim 1, wherein organizing the queue according to the behavior-based policy comprises receiving a vote from one of the participants regarding a relevancy of an utterance spoken by the current speaker.

7. A method as defined in claim 6, further comprising incrementing a second point total associated with the current speaker in response to the vote indicating that the utterance is substantially relevant, and decrementing the point total associated with the current speaker in response to the vote indicating that the utterance is substantially irrelevant.

8. A method as defined in claim 1, wherein organizing the queue according to the behavior-based policy comprises comparing a duration of speaking of the current speaker to a threshold.

9. A method as defined in claim 8, further comprising incrementing a second point total associated with the current speaker in response to determining that the duration exceeds the threshold, and decrementing the second point total in response to determining that the duration is equal to or greater than the threshold.

10. A method as defined in claim 1, wherein organizing the queue according to the behavior-based policy comprises incrementing a second point total associated with a third participant in response to the third participant attempting to interrupt the current speaker.

11. A tangible machine readable storage medium comprising instructions that, when executed, cause a machine to perform operations comprising:

classifying participants of the conference call in a hierarchy according to respective priority values;

detecting an attempt of a first participant and a second participant to speak at substantially a same time;

detecting which one of the first and second participants has a lower priority ranking;

blocking an audio signal of the one of the first participant and the second participant having the lower priority ranking;

placing an identifier associated with the blocked one of the first and second participants in a queue;

organizing the queue according to a behavior-based policy, wherein organizing the queue according to the behavior-based policy comprises comparing an utterance of a current speaker to a keyword associated with the conference call to determine a relevancy of the utterance; and

increasing a first point total associated with the current speaker in response to determining that the utterance is substantially relevant, and decreasing the first point total associated with the current speaker in response to determining that the utterance is substantially irrelevant.

12. A storage medium as defined in claim 11, wherein the operations further comprise enabling the audio signal of a second one of the first and second participants when the one of the first and second participants is finished speaking and when the second one of the first and second participant is in a first position of the queue.

13. A storage medium as defined in claim 11, wherein the operations further comprise organizing the queue according to the priority values of blocked participants.

14. A storage medium as defined in claim 11, wherein the operations further comprise organizing the queue according to a time at which attempted interruptions occur.

15. A storage medium as defined in claim 11, wherein organizing the queue according to the behavior-based policy comprises receiving a vote from one of the participants regarding a relevancy of an utterance spoken by the current speaker.

16. A storage medium as defined in claim 11, wherein organizing the queue according to the behavior-based policy comprises comparing a duration of speaking of the current speaker to a threshold.

17. A storage medium as defined in claim 11, wherein organizing the queue according to the behavior-based policy comprises incrementing a second point total associated with a third participant in response to the third participant attempting to interrupt the current speaker.

18. An apparatus, comprising:

a memory comprising machine readable instructions;

a processor to execute the instructions to cause a machine to perform operations comprising;

detecting an attempt of a first participant and a second participant to speak at substantially a same time;

detecting which one of the first and second participants has a lower priority ranking;

blocking an audio signal of the one of the first participant and the second participant having the lower priority ranking;

placing an identifier associated with the blocked one of the first and second participants in a queue;

organizing the queue according to a behavior-based policy, wherein organizing the queue according to the behavior-based policy comprises comparing an utterance of a current speaker to a keyword associated with the conference call to determine a relevancy of the utterance; and

increasing a first point total associated with the current speaker in response to determining that the utterance is substantially relevant, and decreasing the first point total associated with the current speaker in response to determining that the utterance is substantially irrelevant.

19. An apparatus as defined in claim 18, wherein the operations further comprise enabling the audio signal of a second one of the first and second participants when the one of the first and second participants is finished speaking and when the second one of the first and second participant is in a first position of the queue.

20. An apparatus as defined in claim 18, wherein the operations further comprise organizing the queue according to the priority rankings of blocked participants.
