Abstract: The present invention provides a method and apparatus (100) for capturing and analyzing customer interactions, the apparatus comprising a multi-segment interaction capture device (324), an initial set up and calibration device (326), a pre-processing and context extraction device (328) and a rule-based analysis engine (300).
Abstract: A method and apparatus for verifying the authenticity and integrity of an ordered sequence of digital video frames, without having access to the original recording, by embedding therein a respective series of digital signatures based on a secret key, or keys, and on the video content of respective frames. Signatures are camouflaged by embedding in transform coefficients of a transformed representation of the video data in parts of the frame corresponding to motion. If there is sufficient motion to contain all of the signature bits, a supplementary technique embeds in high-texture areas of a frame. A final fall-back is to embed in a pre-defined default zone. A method of predicting when supplementary embedding is needed enables the process to be applied in a single pass allowing real-time operation. Verification is done during decoding by comparing, for identity, embedded signatures with signatures calculated anew using the method employed to embed.
Abstract: A method and apparatus for improving speech recognition results for an audio signal captured within an organization, comprising: receiving the audio signal captured by a capturing or logging device; extracting a phonetic feature and an acoustic feature from the audio signal; decoding the phonetic feature into a phonetic searchable structure; storing the phonetic searchable structure and the acoustic feature in an index; performing phonetic search for a word or a phrase in the phonetic searchable structure to obtain a result; activating an audio analysis engine which receives the acoustic feature to validate the result and obtain an enhanced result.
Abstract: A method and apparatus for determining whether a speaker uttering an utterance belongs to a predetermined set comprising known speakers, wherein a training utterance is available for each known speaker. The method and apparatus test whether features extracted from the tested utterance provide a score exceeding a threshold when matched against one or more of models constructed upon voice samples of each known speaker. The method and system further provide optional enhancements such as determining, using, and updating model normalization parameters, a fast scoring algorithm, summed calls handling, or quality evaluation for the tested utterance.

Abstract: The disclosed method and apparatus combine interactions and transactions in order to detect fraud acts or fraud attempts. In one embodiment, one or more interactions is correlated with one or more transactions, the interactions is and transactions features are combined, and features are extracted from the combined structure. The features are compared against one or more profiles, and a combined risk score is determined for the interactions or transactions. If the risk score exceeds a predetermined threshold, a preventive/corrective action can be taken. In another embodiment, behavioral characteristics extracted from one or more interactions associated with a transaction, with a risk score obtained by analyzing the transaction. The behavioral characteristic are used to enhance suspicion level related to a transaction being fraudulent, and to enable the taking of measures related to the transaction or to the person handling the transaction.
Abstract: A method and apparatus for indexing one or more audio signals using a speech to text engine and a phoneme detection engine, and generating a combined lattice comprising a text part and a phoneme part. A word to be searched is searched for in the text part, and if not found, or is found with low certainty is divided into phonemes and searched for in the phoneme parts of the lattice.
Abstract: A method and apparatus for integrating intercepted information with information obtained from an at least one data retention source, the method comprising receiving intercepted information from an interception source, receiving information from a data retention source, and analyzing the information received from the data retention source, in association with the intercepted information. The intercepted information can comprise meta data related to the intercepted communications, and/or the contents of the communication themselves. This enables a user such as a law enforcement agency to reveal possibly indirect connections between target entities s wherein the connections involve non-target entities. The method and apparatus combine interception and content analysis methodologies with traffic analysis techniques.

Abstract: An apparatus and methods for generating an ontology for a domain based on analysis performed on interactions captured in the domain. The analysis provides groups of concepts which are used as topics appearing or retrieved from the interactions are used as topics or concepts in the ontology. Concepts belonging to one group are indicated as connected within the ontology. The ontology can then be used in analyzing further interactions and provide meaning, content and relationships between concepts.

Abstract: A method for reliably communicating unreliable protocol packets by encapsulating one or more unreliable protocol packets in a packet constructed according to a predefined format. The method further employs an acknowledgement mechanism whereby a receiver of packets acknowledges reception by responding with a packet containing information pertaining to received packets. A sender retransmits packets for which no acknowledgement was received within a predefined period of time.

Abstract: A method and apparatus for segmenting an audio interaction, by locating anchor segment from each side of the interaction, iteratively classifying additional segments into one of the two sides, and scoring the resulting segmentation, If the score result is below a threshold, the process is repeated until the segmentation score is satisfactory or until a stopping criterion is met. The anchoring and the scoring steps comprise using additional data associated with the interaction, a speaker thereof, internal or external information related to the interaction or to a speaker thereof or the like.
Abstract: In a multi-lingual environment, a method and apparatus for determining a language spoken in a speech utterance. The method and apparatus test acoustic feature vectors extracted from the utterances against acoustic models associated with one or more of the languages. Speech to text is then performed for the language indicated by the acoustic testing, followed by textual verification of the resulting text. During verification, the resulting text is processed by language specific NLP and verified against textual models associated with the language. The system is self-learning, i.e., once a language is verified or rejected, the relevant feature vectors are used for enhancing one or more acoustic models associated with one or more languages, so that acoustic determination may improve.
