Embodiment Construction

[0027] In the present disclosure, the term "group voice telecommunication" is intended to include various activities in which a plurality of participants located at different physical locations communicate with each other in a group manner simultaneously. In other words, the receiver should be able to receive simultaneous transmissions from at least two other participants. Such "group voice telecommunication" includes eg common teleconferencing methods, but also different solutions based eg on the push-to-talk concept. In the examples given below, the term "teleconferencing" is sometimes used to illustrate the principles of the present invention. However, the described embodiments should not be construed as limiting the scope of any particular teleconferencing standard or general interpretation of the term "teleconferencing." Rather, the following embodiments can be applied to many different systems for general group voice telecommunication.

[0028] The basic concept of the...

Abstract

A method of audio scene management in a teleconference or other group sound telecommunication is presented, in which teleconference at least a first transmitting party, a second transmitting party and a receiving party participates. The method comprises receiving (210) of signals representing sound of the first transmitting party and sound of the second transmitting party. The method further comprises obtaining (212) of measures of sound activity for the first and second transmitting parties, respectively and selecting (214) a first angle and / or a second angle based on the obtained measures of sound activity. The method further comprises processing (216) of the received signals into processed signals such that sound from the first transmitting party is experienced by the receiving party as emanating from the first angle while sound from the second transmitting party is experienced as emanating from the second angle, with respect to the receiving party. Finally signals representing the processed signals are outputted (218).

Description

technical field [0001] The present invention relates generally to methods and apparatus for group voice telecommunication, and in particular to such methods and apparatus associated with perceived direction of sound. Background technique [0002] In many telecommunications systems today, different kinds of teleconferencing services are provided. In a teleconferencing session, more than two parties can participate simultaneously and exchange information in any direction. A general effort is to provide a communication scenario as close as possible to a real-world meeting. [0003] In a real world meeting, participants are usually seated around a table, and when someone speaks, the rest of the participants usually turn their heads towards the speaker in order to look at the speaker and maximize the correlation of the speech reaching their respective ears. This maximizes the signal-to-noise ratio. When more than one person is speaking at the same time, the human auditory syst...
