In this paper we analyze the possibilities of using speech analytics and speech technologies to monitor the information space. The “Analyze” speech analytics system is used to perform audio data analysis. Analyze, an automated keyword spotting system, is based on large vocabulary continuous speech recognition approach. Our system can handle both previously recorded audio files, and analyze the voice stream in real time. If we include a keyword spotting system into our information space monitoring systems, we will significantly expand the range of information sources and monitor the controlled environment more effectively.
