Real time voice quality statistics in audio teleconferencing
View Patent ↗A method and system and computer readable medium for a voice quality measuring device that provides real-time, near real-time or contemporaneous voice quality statistics about impairments external to the voice quality conference bridge system, i.e. from participant's calls coming from a communication network into a voice quality conference bridge system is disclosed. The reports generated by the voice quality statistics provided by the voice quality measuring device will enable carriers to identify voice quality impairments. Moreover, the reports will also enable the customers to see, by means of the voice quality statistics, on a call-by-call basis, whether any voice quality impairments are external to the conferencing bridge system.
1. A method for determining real time voice quality statistics for each participant of an audio conference, comprising:
generating the audio conference comprising a plurality of participant calls;
utilizing a voice quality measuring device to collect and measure voice quality statistics concerning at least one of the participant's calls of the audio conference;
reporting in real-time or near real-time voice quality statistics collected and measured from the voice quality measuring device communicatively coupled to an application server to at least one of an operator, a moderator, a customer, and an automatic application programming interface; and
detecting a deficiency impact of the measured voice quality statistics as measured through the voice quality measuring device, and providing an automatic command via an automatic application programming interface to reduce the deficiency impact as indicated from the voice quality statistics to correct the deficiency.
2. The method of claim 1 further comprising collecting voice quality statistics data continuously and non-intrusively on an all channels of the audio conference on a per-call basis.
3. The method of claim 1 wherein voice quality statistics include transmission rating (R) factors including listening quality (R-LQ) and conversational quality (R-CQ), mean opinion scores (MOS) including listening quality (MOS-LQ) and conversational quality (MOS-CQ), noise levels, speech levels, hybrid echo delay, hybrid echo return loss, acoustic echo delay, weighted acoustic echo path loss echo objection rate per ITU-T g.131, packet jitter, packet delay or packet counts.
4. The method of claim 1 wherein reporting to at least one of an operator, an automated application programming interface, an automated action system, a moderator and a customer in real-time or near real-time comprises reporting via a at least one of a web page, and graphical user interface.
5. The method of claim 1 wherein the customer observes the real-time or near real-time impacts regarding the participant calls that are coming from a PSTN as part of the audio conference.
6. The method of claim 5 further comprising addressing the impacts regarding at least one of the participant's call in real time by at least one of the operator, an automated application programming interface, an automated action system, the moderator and the customer.
7. The method of claim 5 wherein addressing the impacts regarding the at least one participant's call includes at least one of the operator, an automated application programming interface, an automated action system, the moderator and the customer muting the call, disconnecting the call, and adjusting the volume.
8. The method of claim 1 wherein the voice quality statistic monitoring device allows the voice quality statistics of at least one of the participant's calls of the audio conference to be displayed to an application programming interface via a web page or other graphical user interface such that the application programming interface can automatically and internally report a problem and remedy the problem.
9. The method of claim 1 wherein the voice quality statistic monitoring device allows the voice quality statistics of at least one of the participant's calls in the audio conference bridge to be displayed to an operator.
10. The method of claim 1 wherein the voice quality statistic monitoring device allows the voice quality statistics of at least one of the participant's calls in the audio conference to be displayed to a moderator via a web page or other graphical user interface via the Internet in real time or near real time.
11. The method of claim 1 further comprising the application server collecting voice quality statistics from the voice quality measuring device at preconfigured intervals.
12. The method of claim 1 further comprising the application server collecting voice quality statistics from the voice quality measuring device only when the statistics change and reach a preselected threshold.
13. The method of claim 1 further comprising pulling real time voice quality statistics by the application server from the voice quality measuring device.
14. The method of claim 1 further comprising pushing real time voice quality statistics to the application server from the voice quality measuring device.
15. The method of claim 1 further comprising coupling the application server to a media gateway through the voice quality measuring device.
16. The method of claim 1 further comprising coupling the application server to a media gateway through the voice quality measuring device, a load balancer and a conference media server.
17. The method of claim 1 , wherein the automatic application programming interface is a voice recognition interface.
18. The method of claim 1 further comprising a voice response unit employed in conjunction with the automatic application programming interface, and wherein the voice response unit issues a command in response to reporting voice quality statistics collected and the automatic application programming interface takes action based upon the command.
19. The method of claim 1 wherein at least one of the operator and the moderator predefines actions for the automatic application programming interface to initiate when certain voice quality impairments are summarized in the report.
20. A system for providing real-time or near real-time voice quality statistics for a plurality of customers participating in an audio conference that allows the plurality of customers to obtain information about real time impacts from a plurality of calls coming from the public switched telephone network (PSTN) into the audio conference comprising:
a media gateway configured to accept a plurality of calls from attendees in a corresponding audio conference;
a voice quality measuring device configured configured to provide real time statistics regarding at least one of the plurality of call's quality impacts from the PSTN into the audio conference; and
an application server communicably coupled to the voice quality measuring device, and the PSTN, wherein the application server dispatches voice quality statistics between the voice quality measuring device and at least one of an operator, a moderator, and a customer through at least one of a web page and a graphical user interface, and wherein the application server is configured to detect a deficiency impact of the measured voice quality statistics as measured through the voice quality measuring device, and provide an automatic command via an automatic application programming interface to reduce the deficiency impact as indicated from the voice quality statistics to correct the deficiency.
