Abstract: Methods and systems to perform textual queries on voice communications. The system has an index service for storing a audio content data sets for voice communications. The audio content data sets include at least three audio content data sets for each voice communication. The three audio content data sets include a first audio content data set generated using a speech-to-text conversion technique, a second audio content data set generated using a phoneme lattice technique, and a third audio content data set generated using a keyword identification technique. The system includes a search engine configured to: receive search criteria from a user, the search criteria having at least one keyword; search each of the first, second and third audio content data sets for at least a portion of the plurality of voice communications to identify voice communications matching the search criteria; and combine the voice communications identified by each search to produce a combined list of identified voice communications.

Abstract: A user-profiling method for providing advertisement data and/or online content to a user and a computer program. In the user-profiling method a user provided with a computing device maintains a voice and/or a video communication with a second user through a communications provider, the method comprising: receiving a profiling engine said voice and/or said video communication from said communications provider as an input; processing said profiling engine, by means of an algorithm, a plurality of keywords related to data identifying a plurality of profiling parameters obtained from said voice or said video communication in order to obtain a user profile, and providing data advertisement and/or online content to said user on the basis of said obtained user profile.

Abstract: A system and a method for analyzing the content of a voice conversation. In particular a system for analyzing the content of a voice conversation, comprising a communication block which establishes and manages the communication session between the parties of said conversation; a keyword module in communication with a plurality of information sources for obtaining and storing keywords relevant to the parties; and an extraction block which extracts at least part of said conversation based at least in part on keywords stored in the keyword module and related to the parties.
