Natural-language surveillance of packet-based communications
First Claim
1. A method comprising:
- a speech-analysis platform receiving speech data representing at least part of a speech session;
the speech-analysis platform comparing the speech data with each of at least one stored speech-characteristics profile in an automated manner, wherein each such profile is associated with a person that is a target of surveillance, wherein the comparing step comprises using natural-language-processing (NLP) to compare the speech data with the at least one stored speech-characteristics profile on each of a lexical level, a syntactic level, a semantic level, and a discourse level, wherein said using of NLP does not comprise conducting voiceprint analysis;
the speech-analysis platform determining in an automated manner from said using of NLP whether the speech data matches any of the profiles; and
if the speech-analysis platform determines from said using of NLP that the speech data matches at least one of the profiles on each of the lexical level, the syntactic level, the semantic level, and the discourse level, the speech-analysis platform responsively storing an indication that the speech data matches at least one of the profiles.

Abstract
Methods and systems are provided for natural-language surveillance of packet-based communications. Speech data is received, representing at least part of a speech session. The speech data is compared with at least one speech-characteristics profile in an automated manner. The comparing step comprises using natural-language-processing (NLP) to compare the speech data with the profiles on at least one of a lexical level, a syntactic level, a semantic level, a discourse level, and a pragmatic level. It is determined in an automated manner whether the speech data matches any of the profiles. If the speech data matches at least one profile, an indication that the speech data matches the at least one matching profile is responsively stored.
