System and Method for Three-Way Call Detection

摘要

A system for detecting three-way calls in a monitored telephone conversation includes a speech recognition processor that transcribes the monitored telephone conversation and associates characteristics of the monitored telephone conversation with a transcript thereof, a database to store the transcript and the characteristics associated therewith, and a three-way Call detection processor to analyze the characteristics of the conversation and to detect therefrom the addition of one or more parties to the conversation. The system preferably includes at least one domain-specific language model that the speech recognition processor utilizes to transcribe the conversation. The system may operate in real-time or on previously recorded conversations. A query and retrieval system may be used to retrieve and review call records from the database.

1. A system for detecting a presence of a third party participating in a monitored telephone conversation, the system comprising:
a speech recognition module configured to detect a first characteristic of the monitored telephone conversation and a second characteristic of the monitored telephone conversation; a speech analysis module configured to calculate a score for the monitored telephone conversation, the calculating including:
associating a first score with the first characteristic;associating a second score with the second characteristic; andsumming the scaled first weight and the scaled second weight; and a three-way call detection module configured to detect the presence of the third party based on a comparison of the score to a predetermined threshold.
