Abstract
Example methods, apparatus and articles of manufacture to detect echo during teleconferences are disclosed. A disclosed example method includes collecting first signal data for a first teleconference leg of a teleconference, collecting second signal data for a second teleconference leg of the teleconference, computing an echo detection metric from the first and second signal data, and comparing the echo detection metric to a threshold to determine whether an echo is likely present on the first teleconference leg of the teleconference.
Claims17
A method comprising:
- collecting first signal data for a first teleconference leg of a teleconference;
- collecting second signal data for a second teleconference leg of the teleconference;
- computing an echo detection metric from the first and second signal data, wherein the echo detection metric comprises a percentage of time the first teleconference leg is muted at a teleconference bridge;
- comparing a value based on the echo detection metric to a threshold;
- and
- identifying the first teleconference leg of the teleconference as a likely source of an echo in response to the value being greater than the threshold.
An apparatus comprising:
- a memory comprising machine readable instructions;
- and
- a processor to execute the machine readable instructions to perform operations comprising:
- accessing first signal data for a first teleconference leg of a teleconference
- accessing second signal data for a second teleconference leg of the teleconference;
- computing an echo detection metric from the first and second signal data, the echo detection metric representing a percentage of time the first teleconference leg is muted at a teleconference bridge;
- comparing a value based on the echo detection metric to a threshold;
- and
- identifying the first teleconference leg of the teleconference as a likely source of an echo based on the comparison of the value to the threshold.
A tangible machine-readable storage device comprising instructions that, when executed, cause a machine to perform operations comprising:
- accessing first signal data for a first teleconference leg of a teleconference;
- accessing second signal data for a second teleconference leg of the teleconference;
- calculating an echo detection metric from at least one of the first and second signal data, wherein the echo detection metric comprises a percentage of time the first teleconference leg is muted at a teleconference bridge;
- comparing the echo detection metric to a threshold;
- and
- identifying the first teleconference leg of the teleconference as likely including an echo in response to the echo detection metric being greater than the threshold.
