A method for managing at least three-party dialogs between communication devices, the method comprising: receiving, by a processor of a computing device, digital connection requests from at least three communication devices already connected to each other over a plain old telephone service connection; establishing, by the processor, digital connections with the at least three communication devices; performing, by the processor, one or more tests on the at least three communication devices to determine whether the at least three communication devices include software or logic enabling the at least three communication devices to digitally communicate and transmit audio signals for analysis; switching, by the processor, the connection between the at least three communication devices from the plain old telephone service connection to the digital connections, when the at least three communication devices include the software or logic, thereby enabling the at least three communication devices to communicate with each other via the computing device over the digital connections; receiving, by the processor, audio signals from at least a portion of the at least three communication devices, the audio signals being part of at least a three-party dialog between users of the at least three communication devices; splitting, by the processor, each of the received audio signals into corresponding first signals and second signals; transmitting, by the processor, the first signals to the at least three communication devices over the digital connections in the form of audio to be output by each of the at least three communication devices; analyzing, by the processor, the second signals to produce measurements of features of the second signals; transmitting, by the processor, to at least one of the plurality of communication devices, feedback data comprising at least a portion of measurements of features of the second signals, the feedback data contextualizing the participation of each of the users of the at least three communication devices during the at least three- party dialog; and maintaining the plain old telephone service connection. receiving, by a processor of a computing device, digital connection requests from at least three communication devices already connected to each other over a plain old telephone service connection; establishing, by the processor, digital connections with the at least three communication devices; performing, by the processor, one or more tests on the at least three communication devices to determine whether the at least three communication devices include software or logic enabling the at least three communication devices to digitally communicate and transmit audio signals for analysis; switching, by the processor, the connection between the at least three communication devices from the plain old telephone service connection to the digital connections, when the at least three communication devices include the software or logic, thereby enabling the at least three communication devices to communicate with each other via the computing device over the digital connections; receiving, by the processor, audio signals from at least a portion of the at least three communication devices, the audio signals being part of at least a three-party dialog between users of the at least three communication devices; splitting, by the processor, each of the received audio signals into corresponding first signals and second signals; transmitting, by the processor, the first signals to the at least three communication devices over the digital connections in the form of audio to be output by each of the at least three communication devices; analyzing, by the processor, the second signals to produce measurements of features of the second signals; transmitting, by the processor, to at least one of the plurality of communication devices, feedback data comprising at least a portion of measurements of features of the second signals, the feedback data contextualizing the participation of each of the users of the at least three communication devices during the at least three- party dialog; and maintaining the plain old telephone service connection.
