Abstract

A system and method are provided for providing users of voice conferencing with indications of the quality perceived by other users of the voice conferencing system. A voice conferencing bridge measures the quality of the each user's channel, and provides real-time feedback to users whose channel quality is inadequate and that other users cannot hear them clearly. The feedback may be in the form of in-band or out-of-band signals, indicating for example that the user should speak louder, should mute while off-line, or warning the user that his or her channel may be muted automatically. The last option is particularly useful if a participant has temporarily left the conference and is playing music or hold tones while absent.

Claims (59)

1. A method of providing feedback to an end user device of a voice conference, comprising:

measuring a quality of an input signal received from the end user device at a conference bridge;

providing a notification signal to the end user device indicative of the quality of the input signal;

displaying at the end user device an indication of the quality of the signal;

determining whether the input signal includes unwanted content; and

when the input signal includes the unwanted content, providing a notification signal to the end user device indicating that the input signal will be muted, muting the input signal, and keeping in the input signal muted until the unwanted content is no longer present.

2. A computer-readable medium storing instructions for use in a conference bridge and for providing feedback to an end user device of a voice conference, the instructions comprising:

instructions for measuring a quality of an input signal received from the end user device at the conference bridge;

instructions for providing a notification signal to the end user device indicative of the quality of the input signal;

instructions for determining whether the input signal includes unwanted content;

instructions for providing a notification signal to the end user device indicating that the input signal will be muted when the input signal includes the unwanted content;

instructions for muting the input signal when the input signal includes the unwanted content; and

instructions for keeping the input signal muted until the unwanted content is no longer present.

3. A method of providing feedback to an end user device of a voice conference, comprising:

measuring a quality of an input signal received from the end user device at a conference bridge;

determining whether the quality of the input signal is unacceptable by comparing the quality with configured thresholds;

if the quality of the input signal is unacceptable, providing a first notification signal to the end user device indicative of the quality of the input signal;

determining whether the input signal includes unwanted content; and

when the input signal includes the unwanted content, providing a second notification signal to the end user device indicating that the input signal will be muted, muting the input signal, and keeping in the input signal muted until the unwanted content is no longer present.

4. The method of claim 3 , wherein the first notification signal includes indications of how the quality of the input signal can be improved.

5. The method of claim 3 , further comprising:

determining at least one of

whether an input level of the input signal is below a first threshold,

whether the input level is above a second threshold,

whether a signal to noise ratio of the input signal is above a third threshold, and

whether a Mean Opinion Score of the input signal is above a fourth threshold.

6. The method of claim 3 , further comprising:

determining whether the input signal includes at least one of hold tones, hold music, and excessive background noise.

7. The method of claim 3 , further comprising:

transmitting a warning to the end user device if the input signal is muted.

8. The method of claim 5 , further comprising:

determining whether the input signal includes at least one of hold tones, hold music, and excessive background noise.

9. The method of claim 5 , further comprising:

transmitting a warning to the end user device if the input signal is muted.

10. The method of claim 3 , wherein the notification signal is an in-band voice message.

11. The method of claim 3 , wherein the notification signal is an out-of-band signal for altering displays on the end user device.

12. The method of claim 3 , further comprising:

when the user device is about to be muted, sending a mute notification message to the end user device, wherein the mute notification message comprises a reason for the muting and instructions on how a user may reverse the muting.

13. The method of claim 10 , wherein the in-band voice message comprises a pre-recorded message that both indicates a problem in the input signal and suggests how to remedy the problem.

14. The method of claim 3 , further comprising

providing the end user device with a continuous indication of the quality of the input signal.

15. The method of claim 14 , further comprising:

displaying the indication of the quality of the signal as a bar meter on the end user device.

16. A computer-readable storage medium for use in a conference bridge and including instructions for providing feedback to an end user device of a voice conference, comprising:

instructions for measuring a quality of an input signal received from the end user device at the conference bridge;

instructions for determining whether the quality of the input signal is unacceptable by comparing the quality with configured thresholds;

instructions for providing a first notification signal to the end user device indicative of the quality of the input signal in the event that the quality of the input signal is unacceptable;

instructions for determining whether the input signal includes unwanted content;

instructions for providing a second notification signal to the end user device indicating that the input signal will be muted when the input signal includes the unwanted content:

instructions for muting the input signal when the input signal includes the unwanted content and

instructions for keeping the input signal muted until the unwanted content is no longer present.

17. The computer-readable storage medium of claim 16 , further comprising:

instructions for determining at least one of

whether an input level of the input signal is below a first threshold,

whether the input level is above a second threshold,

whether a signal to noise ratio of the input signal is above a third threshold, and

whether a Mean Opinion Score of the input signal is above a fourth threshold.

18. The computer-readable storage medium of claim 17 , further comprising:

instructions for determining whether the input signal includes at least one of hold tones, hold music, and excessive background noise.
