This paper describes our effort with an automatic transcription of TV ice-hockey commentaries1. The ice-hockey matches were played during the World Championships 2000 and 2001 in St. Petersburg (Russia) and Hannover (Germany), respectively and were transmitted by the Czech TV channels NOVA and CTV1 with an accompanying commentary of Robert Záruba. Annotation rules designed for the processing of a commentary comprising specific background noise are formed and a list of non-speech events is proposed. A baseline ASR system was built using commentaries of 15 training matches and tested using utterances randomly selected from 4 tested matches. Several types of adaptive lexicons were designed to decrease a number of OOV words and improve recognition accuracy.
