Embodiment Construction

[0027] In the content disclosed in the present invention, the term "group voice remote communication" is intended to include various behaviors in which multiple participants located at different physical locations communicate with each other in a group manner at the same time. In other words, the receiver should be able to receive simultaneous transmissions from at least two other participants. This "group voice remote communication" includes, for example, common remote teleconference methods, but also includes different solutions based on, for example, the concept of push-to-talk. In the embodiments given below, the term "remote conference call" is sometimes used to illustrate the principle of the present invention. However, the described embodiments should not be construed as limiting the scope of any special teleconference standard or the general interpretation of the term "teleconference". On the contrary, the following embodiments can be applied to many different systems ...

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 of signals representing sound of the first transmitting party and sound of the second transmitting party. The method further comprises obtaining of measures of sound activity for the first and second transmitting parties, respectively and selecting a first angle and / or a second angle based on the obtained measures of sound activity. The method further comprises processing 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.

Description

Technical field [0001] The present invention generally relates to methods and devices for group voice remote communication, and specifically relates to such methods and devices associated with perceived sound directions. Background technique [0002] In today's many telecommunication systems, different types of teleconference services are provided. In a teleconference session, more than two parties can participate at the same time and exchange information in any direction. The general effort is to provide communication scenarios that are as close as possible to real-world meetings. [0003] In a real-world conference, participants usually sit around a table, and when someone is speaking, the remaining participants usually turn their heads towards the speaker in order to look at the speaker and maximize the relevance of the speech to their respective ears. This maximizes the signal-to-noise ratio. When more than one person is talking at the same time, the human auditory system ca...
