Abstract: A single audio interface signal switching circuit and a single audio interface switching device are provided by the embodiments of the present disclosure, which sets only one single audio interface and uses a working mode switching module to control a driver chip to generate different drive signals, in order to control working states of an audio signal output module, a time code input module, and a time code output module electrically connected with the driver chip. Since there is only one audio interface, and a working mode of the single audio interface switching device is controlled by the working mode switching module, so that a volume of the single audio interface switching device is reduced.

Abstract: Provided is a voice communication system that notifies a terminal device of transmission restriction information when the number of received voice signals reaches a predetermined number. A server device continuously counts the number of simultaneously received voice signals. A first terminal device transmits, to the server device, a voice signal with identification information of a second terminal device. The server device transfers, to the second terminal device, the voice signal transmitted from the first terminal device. However, when the number of simultaneous receptions of the voice signals reaches a predetermined restriction value, the server device transfers, to the second terminal device, the received voice signal with transmission restriction information attached thereto. The second terminal device does not transmit a voice signal, even if a user performs a transmission operation, during reception of the voice signal with the attached transmission restriction information.

Abstract: Embodiments described herein provide for passive caller verification and/or passive fraud risk assessments for calls to customer call centers. Systems and methods may be used in real time as a call is coming into a call center. An analytics server of an analytics service looks at the purported Caller ID of the call, as well as the unaltered carrier metadata, which the analytics server then uses to generate or retrieve one or more probability scores using one or more lookup tables and/or a machine-learning model. A probability score indicates the likelihood that information derived using the Caller ID information has occurred or should occur given the carrier metadata received with the inbound call. The one or more probability scores be used to generate a risk score for the current call that indicates the probability of the call being valid (e.g., originated from a verified caller or calling device, non-fraudulent).

Abstract: A fraud detection system receives incoming calls and determines a fraud score indicating the likelihood that the incoming call is from a fraudulent or malicious caller. The system is able to determine the age of a telephone number of an incoming call and from it determine a fraud score for the call.

Abstract: A fraud detection system receives incoming calls and determines a fraud score indicating the likelihood that the incoming call is from a fraudulent or malicious caller. The system is able to learn patterns of fraudulent activity from historical call records and feedback provided by a subscriber.

Abstract: The present disclosure describes receiving a trigger operation indication that content has been selected by a user device, and determining whether the content offers a recurring audio content data. The operation may also include retrieving a first audio content and transmitting the first audio content to the user device.

Abstract: Systems and methods are described to enable a device of a user to automatically join an ongoing conference, where the device is not currently joined to the conference. A first audio signature is generated based on voices of users already in the conference, and a second audio signature is generated based on an audio signal captured by a microphone of the device associated with the first user when the device associated with the first user was not joined to the conference. The first audio signature and the second audio signature are compared, and in response to determining that first audio signature matches the second audio signature, the device associated with the first user is joined to the conference.

Abstract: A system and method for a cloud callback platform, comprising at least a profile manager, callback manager, interaction manager, media server, context analysis engine, and context aggregator mechanism, allowing users to call a business, agents in contact centers, or other users who are connected to cloud callback platform, and, failing to connect to the individual they called, or by request, allow for an automatic callback object to be created, whereby the two users may be automatically called and bridged together at a time when both users are available, and a context summary report is sent to one or more user. The system and method implement predictive logic to determine the most successful alternative communication channel to use to bridge the two parties.
