The projects aims at massive usage of streamed audio for a qualitative improvement of LID (automatic
language identification) system accuracy. The speech processing research group at Faculty of Information
Technology, Brno University of Technology (Speech@FIT) disposes of a state-of-the-art LID system based
on acoustic and phonotactic modeling. For further improvement of its accuracy, it is crucial to gather huge
amounts of language-specific data. In the framework of this project, such data will be collected from available
streamed sources (Internet radios), on-line stored, parameterized and processed. We will develop software
for training of LID models. Resulting models and algorithms will be evaluated in international evaluation
campaigns organized by NIST and in cooperation with Czech law enforcement forces.
