This paper presents the language identification (LID) systemdeveloped in Speech@FIT. The system consists of twoparts: Acoustic LID determines the language directly on thebasis of features derived from the speech signal. We haveimproved existing approaches by adding discriminative trainingof acoustic models. In phonotactic LID, speech is firsttranscribed by phoneme recognizer into strings or graphs (lattices)of phonemes. On these, language models are trainedto capture statistics of sequences of phonemes. We have pioneeredthe use of so called îanti-modelsî for this task. All experimentalresults are reported on standard NIST 2003 data;comparison with other published results is favorable to oursystem.
