摘要： A conference terminal and an echo cancellation method for a conference are provided. In the echo cancellation method, a synthetic speech signal is received. The synthetic speech signal includes a user speech signal of a speaking party corresponding to a first conference terminal of multiple conference terminals and an audio watermark signal corresponding to the first conference terminal. One or more delay times corresponding to the audio watermark signal are detected in a received audio signal. The received audio signal is recorded through a sound receiver of a second conference terminal of the conference terminals. An echo in the received audio signal is canceled according to the delay time.

摘要： Determining the angle of sound relative to the centerline of a microphone array. The angle of the centerline of a camera field-of-view (FoV) and the angle of the camera FoV is determined. Knowing the angle from the centerline of the microphone array of the particular sound and then the angle of the centerline of the camera FoV and angles of the camera FoV allows a determination if the sound is inside the FoV of the camera. If so, the microphones are unmuted. If not, the microphones are muted. As the camera zooms or pans, the changes in camera FoV and centerline angle are computed and used with the sound angle, so that the muting and unmuting occurs automatically as the camera zoom and pan angle change.

摘要： Embodiments for delay-induced miscommunication reduction are provided. The embodiment may include capturing data streams transmitted between participants in an A/V exchange; translating, on a sender device prior to transmission to a recipient device, an audio stream within the data streams to text; timestamping, on a sender device prior to transmission to the recipient device, each word in the translated audio stream; transmitting the audio stream and the sender-side translated and timestamped audio stream to the recipient device; translating, on the recipient device, the transmitted audio stream to text; timestamping, on the recipient device, each word in the translated audio stream; determining a lag exists in the A/V exchange based on a comparison of each timestamp for corresponding words on the sender-side translated and timestamped audio stream and the recipient-side translated and timestamped audio stream; and generating a true transcript of an intended exchange between the participants based on the comparison.

摘要： A device for communication includes one or more processors configured to receive, during an online meeting, a speech audio stream representing speech of a first user. The one or more processors are also configured to receive a text stream representing the speech of the first user. The one or more processors are further configured to selectively generate an output based on the text stream in response to an interruption in the speech audio stream.

摘要： The present invention, belonging to the technical field of data transmission, relates to an integrated intelligent interaction machine. The integrated intelligent interaction machine comprises a signal transmission device, a processing device, a upper computer and a network transmission device, wherein the signal transmission device is connected to the processing device, the processing device is connected to the upper computer, and the upper computer is connected to the processing device through the network transmission device. The signal transmission device is used to receive a screen transmission signal and transmit it to the processing device, and the processing device is used to process the screen transmission signal to obtain screen transmission data and transmit the screen transmission data to the upper computer. The upper computer is used to connect to an external network and output a network signal to the network transmission device, and the network transmission device transmits the network signal to the processing device. The upper computer is used to connect the external network and the internal device of the equipment to provide the network signal for the processing device, thereby realizing the communication between the processing device and the external network. The screen transmission data and the network signal are transmitted through different paths, so as to carry out screen transmission communication in the equipment and network sharing, respectively, thereby improving the data transmission convenience of the integrated intelligent interaction machine.

摘要： The interactive and shared surface technique described herein employs hardware that can project on any surface, capture color video of that surface, and get depth information of and above the surface while preventing visual feedback (also known as video feedback, video echo, or visual echo). The technique provides N-way sharing of a surface using video compositing. It also provides for automatic calibration of hardware components, including calibration of any projector, RGB camera, depth camera and any microphones employed by the technique. The technique provides object manipulation with physical, visual, audio, and hover gestures and interaction between digital objects displayed on the surface and physical objects placed on or above the surface. It can capture and scan the surface in a manner that captures or scans exactly what the user sees, which includes both local and remote objects, drawings, annotations, hands, and so forth.
