According to one embodiment, a signal processing apparatus correlates a plurality of communication terminals as a group and enables one-to-many communications in the group. The signal processing apparatus includes processing circuitry. The processing circuitry assigns a transmission right to one of the communication terminals in the group. The processing circuitry generates text data based on voice data from said one of the communication terminals in possession of the transmission right. The processing circuitry gives a texting completion notice indicative of completion of texting processing to the communication terminals in the group. The processing circuitry transmits, after the texting completion notice is given, the generated text data to at least one of the communication terminals in the group.

A call processing method and an electronic device are provided. The method is performed by an electronic device and includes: in a case that a call is connected successfully, obtaining the number of speakers in the current call. The method further includes: when the number of speakers is greater than a preset threshold, determining whether a user of the electronic device is a target user. The method additionally includes: if the user of the electronic device is a non-target user, disabling a speaking channel of the electronic device; and if the user of the electronic device is a target user, keeping the speaking channel of the electronic device on.

A computer-implemented method comprises establishing, by media servers, a video conference for client computing devices, each media server receiving audio data and video data from a local subset of the client computing devices, selecting, by each media server, a portion of the local subset for which to send audio data to other media servers, sending, by each media server, audio data associated with the portion to other media servers, after receiving audio data from other media servers, generating, by each media server, ordered global list data that identifies each client computing device for which the media server has received audio data, based on the global list data and by each media server to other media servers, sending video data for each client computing device of the local subset that satisfies a threshold value.

A conference system includes a conversation state determiner that determines whether or not the state of first and second users is a direct conversation state in which direct conversation is possible without using a speech system, and an output controller that controls whether or not to cause the speech system to output a first acquired voice from a second speaker, based on the determination result of the conversation state determiner.

A conferencing system that is connected to multiple information processing devices over a network and provides each of the multiple information processing devices with a conference screen, comprises: a first participant information obtaining unit that obtains first participant information corresponding to a first participant who participates in a video conference by using each of the multiple information processing devices; a second participant information obtaining unit that obtains second participant information related to a second participant who indirectly participates in the video conference together with the first participant; and a display controller that: displays the first participant information obtained by the first participant information obtaining unit in a predetermined display area on the conference screen; and displays the second participant information obtained by the second participant information obtaining unit in the predetermined display area on the conference screen.

Systems and methods for efficient management of an audio/video conference are disclosed. The methods comprise recording voice data of a first user connected to a conference while the user is in a first state, determining the first user is talking while in the first state, and initiating playback of the recorded voice data of the first user to a plurality of other users, wherein a playback rate of the recorded voice data is variable.

Systems and methods for video conference content auto-retrieval and focus based on learned relevance is provided. In accordance with the systems and methods, audio streams and video streams from client devices participating in a video conference are received. Based on the audio streams, a subject being discussed during the video conference at a point in time is determined. A video stream that is most relevant to the subject being discussed during the video conference at the point in time is determined from the video streams. The determined video stream is provided to the client devices for presentation on the client devices while the subject is being discussed during the video conference.

A communication server and accompanying communication devices allow near instantaneous communication between users of the communication devices. A communication device may be configured with multiple channels, where each channel is assigned a corresponding communication device. As the communication devices are registered with the communication server, each communication device has knowledge of other registered communication devices. Thus, communication devices may communicate nearly instantaneously with each other. Furthermore, as the communication device is equipped with multiple channels, a single communication device may host a conference call with other communication devices. In addition, communication device may include multiple buttons to control the communication device, and indicator lights to indicate the status of calls with other communication devices

A system for managing a communication session between a number of participants is provided. The system can analyze activity of each participant and generate recommendations on the communication flow of a meeting. For instance, the system can analyze user activity and other contextual data for each user to determine a recommended speaking arrangement for the participants. The recommendations can be presented to a moderator who can then utilize the recommendations to control the flow of the meeting. Inputs received from the moderator can modify speaking and viewing permissions to emphasize or deemphasize displays and audio of individual participants. In some configurations, the recommendations can be utilized by a system to automatically control permissions for each participant for the purposes of controlling communication and flow of an event, such as an online meeting.

A mobile communication terminal used in a communication system in which audio based on an audio signal transmitted from a given mobile communication terminal having speaking rights is output from another mobile communication terminal, the given mobile communication terminal being selected by a server storing priority rank information indicating a priority rank pertaining to acquisition of the speaking rights for each of a plurality of mobile communication terminals, the mobile communication terminal including a rank signal receiver receiving, from the server, a priority rank signal based on the priority rank information stored by the server and indicating the priority rank for at least a subset of the mobile communication terminals and a display displaying a terminal priority rank based on the priority rank signal when the rank signal receiver receives the priority rank signal.
