Abstract: Systems and methods are provided for processing audio information. An exemplary system may include a communication interface configured to receive a plurality of audio streams obtained by multiple terminal devices. The system may also include a memory and a processor. The processor may execute instructions stored on the memory to perform operations. The operations may include beamforming the plurality of audio streams based on a spectral mask indicating signal and noise presence probabilities. The operations may also include synchronizing the beamformed audio streams and determining signal-to-noise-ratio (SNR) indicators associated with the synchronized audio streams. The operations may further include selecting a candidate audio stream based on the SNR indicators and generating a synthesis audio stream including at least a portion of the candidate audio stream.

Abstract: Systems and methods are provided for processing information of a meeting. An exemplary system may include a communication interface configured to receive meeting information obtained by a plurality of client devices. The meeting information may include multiple audio streams. The system may also include a memory and a processor. The processor may execute instructions stored on the memory to perform operations. The operations may include determining signal-to-noise-ratio (SNR) indicators associated with the audio streams. The operations may also include selecting, from the audio streams, a candidate audio stream based on the SNR indicators. The SNR indicator associated with the candidate audio stream may indicate that the candidate audio stream has a higher average SNR than that of a predetermined number of other audio streams. In addition, the operations may include generating an output data stream including at least a portion of the candidate audio stream.

Abstract: Embodiments of the disclosure provide systems and methods for logging a meeting. The system may include a memory storing computer-executable instructions and a processor. The processor may be configured to execute the instructions to perform operations. The operations may include receiving audio of the meeting captured by at least one microphone device and determining an arriving angle of speech from at least one attendee of the meeting based on the captured audio. The operations may also include generating a data stream based at least in part on the arriving angle of speech, determining an identification of the at least one attendee, and matching the identification to the data stream.

Abstract: Systems and methods for managing a presentation service are provided. An exemplary system may include at least one memory storing computer-executable instructions and at least one processor in communication with the memory. The computer-executable instructions, when executed by the processor, cause the processor to perform operations. The operations may include receiving, from a terminal device, identification information of a user. The operations may also include determining whether the user enrolls in the presentation service based on the identification information. In response to a determination that the user enrolls in the presentation service, the operations may include selecting presentation information associated with the user in a content database. The operations may further include causing a display device associated with the terminal device to display at least part of the presentation information.

Abstract: Embodiments of the disclosure provide a system for managing an access control a meeting. The system may include a communication interface that receives video and audio of the meeting. The system may also include a processor that executes instructions to generate a biometric characteristic for an attendee based on at least one of the video and the audio, and to associate identity information of the attendee with the biometric characteristic based on a comparison of the biometric characteristic with stored biometric characteristics of known users. The processor may also execute the instructions to generate a data stream that includes at least one of the video and the audio of the attendee, to tag the data stream with the identity information based on the associated biometric characteristic, and to selectively cause the data stream to be shown on a display based on selection of the tag.

Abstract: Embodiments of the disclosure provide a system and methods for logging and reviewing a meeting. The system may include a communication interface configured to receive video of the meeting captured by at least one camera device and audio of the meeting captured by at least one microphone device, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the instructions to generate a plurality of data streams based on captured video and captured audio, and to determine identifications of attendees of the meeting based on at least one of the captured video and the captured audio. The processor may also be configured to execute the instructions to transcribe speeches of the attendees based on at least one of the captured audio.
