Procedure and mechanism for controlling and using voice communication

A communications system comprising

• a first microphone configured to receive vocal utterances from a first person and convert those utterances to a voice signal;
• a first processor connected to the first microphone, the first processor configured to receive the voice signal and generate a transmission signal by processing the voice signal;
• a transmitter connected to the first processor, the transmitter configured to transmit the transmission signal via a network;
• a receiver configured to receive a signal input from the network and output a received signal based on the received signal input from the network;
• a second processor connected to the receiver, the second processor configured to receive the received signal and generate a listening signal by processing the received signal;
• and
• a speaker that is connected to the second processor, the speaker configured to receive the listening signal and convert the listening signal to an acoustic signal to be perceived by the first person,
• wherein the second processor is configured such that the processing of the received signal by the second processor to generate the listening signal comprises:
• adding the voice signal branched to the second processor to the received signal to form the listening signal such that the vocal utterances from the first person are includable within the acoustic signal;
• branching the transmission signal to create a branched transmission signal;
• subjecting the branched transmission signal to a variable echo compensation to generate an echo compensation signal matching an anticipated echo of the transmission signal contained in the received signal;
• and
• subtracting the echo compensation signal from the received signal to generate the listening signal.

A communication device comprising:

• a first microphone configured to receive vocal utterances from a user and convert those utterances to a voice signal;
• a first processor connected to the first microphone, the first processor configured to receive the voice signal and generate a transmission signal by processing the voice signal;
• a transmitter connected to the first processor, the transmitter configured to transmit the transmission signal to a network;
• a receiver configured to receive an input signal from the network and output a received signal;
• a second processor connected to the receiver, the second processor configured to receive the received signal and generate a listening signal by processing the received signal, the processing of the received signal comprising:
• adding the voice signal to the received signal such that vocal utterances from the user are obtainable from the generated listening signal,
• branching the transmission signal to create a branched transmission signal;
• subjecting the branched transmission signal to a variable echo compensation to generate an echo compensation signal matching an anticipated echo of the transmission signal contained in the received signal, and
• subtracting the echo compensation signal from the received signal to generate the listening signal;
• and
• a speaker connected to the second processor, the speaker configured to receive the listening signal and convert the listening signal to an acoustic signal to output the acoustic signal such that the acoustic signal is perceivable by the user such that the vocal utterances are hearable by the user via the acoustic signal.
