A method for information processing includes receiving in a computer a corpus of recorded conversations, with two or more speakers participating in each conversation. Respective frequencies of occurrence of multiple words in each of a plurality of chunks in each of the recorded conversations are computed. Based on the frequencies of occurrence of the words over the conversations in the corpus, an optimal set of topics to which the chunks can be assigned is derived, such that the optimal set maximizes a likelihood that the chunks will be generated by the topics in the set. A recorded conversation from the corpus is segmented using the derived topics into a plurality of segments, such that each segment is classified as belonging to a particular topic in the optimal set.

Unsupervised automated topic detection, segmentation and labeling of conversations

Methods and systems are described for recording screen data and audio data relating to a call The screen recording session is initiated and terminated within the controller, based on correlation between audio data and screen data from the call, without requiring involvement with a controller or Computer Telephony Integration (CTI) layer

Call recording with screen and audio correlation

Systems for caller identification and authentication may include an authentication server. The authentication server may be configured to receive audio data including speech of a plurality of telephone calls, use audio data for at least a subset of the plurality of telephone calls to populate a plurality of word clusters each associated with a specific demographic, and/or use audio data for at least one of the plurality of telephone calls to identify the telephone caller making the telephone call based on determining a most similar word cluster of the plurality of word clusters to the audio data of the caller.

Systems and methods for cluster-based voice verification

A terminal and a recording method of the terminal are presented. The terminal includes one or more processors and a memory storing computer readable program, where the one or more processors is configured to monitor call trigger event, and when the call trigger event is detected, trigger the call unit to switch a terminal status; control switching of the terminal status; and initiate a recording operation to start recording of the current call when the terminal status controlled by the call unit is switched to the calling state related to the call trigger event. If a call is performed with the terminal and recording is needed, a recording operation is automatically initiated according to a one-off event trigger and monitoring of the terminal status, which simplifies steps of the recording operation of the terminal, improves usability of the terminal, and achieves a one-click effect of recording and calling.

Terminal and Recording Method of Terminal

A system or method for dynamic redundant call recording may include a plurality of recording devices, each recording device having a plurality of recording resources, and a resource allocator. The resource allocator may receive a request from a call receiving node for commencement of a recording session. It may then attempt to connect to a first one of the plurality of recording devices and if successful, establish a recording session between the call receiving node and the recording device, or if not successful, attempting to connect the recording session controller to a second one of the multiple recording devices. Two resource allocators may operate in parallel to establish dual recording using resources at two different recording devices. Call content may be recorded separately from call metadata and may be integrated with the metadata using a unique call ID.

System and method for dynamic redundant call recording

Methods and systems are described for call recording, e.g. in a VoIP system. At least one endpoint may be configured to terminate a call. A recording system may be configured to record call content data from multiple endpointsA the controller may receive, from a call exchange, interaction metadata relating to calls starting and terminating at the endpoint; receive notifications relating to call content from the recording system; and match the interaction metadata to the notifications.
