摘要： A device (330) is provided in a teleconference system (110-1) that includes multiple microphones (340). The device (330) receives information (350) indicating whether a signal (130), received by the teleconference system (110-1 ), is a speech signal or a non-speech signal, and determines a first state (530) when the information indicates that the signal (130) is a speech signal. The device (330) also determine a second state (540) when the information indicates that the signal (130) is a non-speech signal. When the first state (530) is determined, the device (330) fixes gains associated with the multiple microphones (340) to disable adaptive audio capture, end an acoustic echo controller (320) enabled. When the second state (540) is determined, the device (330) varies the gains associated with the multiple microphones (340) to enable adaptive audio capture, end the acoustic echo controller (320) is disabled.

摘要： Conference bridge (1) for managing an audio scene comprising two or more participants, the conference bridge comprising a mixer (2) and several user channels (3a, 3b, 3N). The conference bridge is arranged to continuously create a 3D positional audio environment signal for each participant as a listening participant, by rendering the speech of each participant as a 3D positioned virtual sound source and excluding the speech of the listening participant, and to distribute each created 3D positional audio environment signal to the corresponding listening participant. Further, the conference bridge is arranged to place the virtual sound source corresponding to each participant at the same spatial position relative the listening participant in every created 3D positional audio environment.

摘要： 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).

摘要： A conference bridge for managing arriving packets of multiple packetized media streams of a non-synchronous packet network includes queue memories (22) arranged to queue arrived packets for each stream. A control unit (24) monitors the queued packets to detect arrival of temporally related packets of the streams. A mixer (16) mixes selected temporally related packets once it has been detected that they have arrived.

摘要： A basic idea for efficient media communication between two nodes in a group communication system is to set up a number, N, of parallel, separate media streams of the same media type in a given direction between the nodes, where N is equal to or greater than 2. Before setting up the media streams, the actual number of media streams is negotiated (Sl). Once the negotiation is completed, the media streams are established (S2). Media data of the same type can then be transferred in parallel, media streams (S3), where each media stream may include media data from a separate source or from a mix of sources. In this way, a richer and/or more personalized rendering of the media data is enabled since media data may be transported as individual media streams and processed locally in a participant, rather than processed and mixed into a single stream by a central mixer.
摘要翻译：在组通信系统中的两个节点之间的有效媒体通信的基本思想是在节点之间的给定方向上建立数个N个相同媒体类型的并行分离的媒体流，其中N等于或大于在设置媒体流之前，协商媒体流的实际数量（S1）。一旦协商完成，就建立媒体流（S2）。然后可以并行地传送相同类型的媒体数据，媒体流（S3），其中每个媒体流可以包括来自单独来源的媒体数据或源的混合。以这种方式，媒体数据的更加丰富和/或更个性化的呈现是可以实现的，因为媒体数据可以作为单独的媒体流传送并在参与者中本地处理，而不是通过中央混合器被处理并混合成单个流。

摘要： In accordance with an example embodiment of the present invention, disclosed is a method and an apparatus thereof for detecting voiced speech in an audio signal. The method comprises calculating an autocorrelation function, ACF, of a portion of an input audio signal and detecting a highest peak of said autocorrelation function within a determined range. A peak width and a peak height of said detected highest peak are determined and based on the peak width and the peak height it is decided whether a segment of an input audio signal comprises voiced speech.
