Psutka Josef V. and Hoidekr, J. and Ircing, P. and Psutka, J. : Automatic transcription of TV ice-hockey commentary . Proceedings , p. 419-423, International Institute of Informatics and Systemics, Orlando, 2003.


Automatic recognition of a TV commentary accompanying an ice-hockey match is usually a hard task due to the spontaneous speech of a commentator put often into a very loud background noise. Although a vocabulary of an ice-hockey commentary seems to be relatively well limited we show that the lexicon formed by collecting words of 15 ice hockey matches provided by one TV commentator does not sufficiently cover commen- taries of new matches and a high OOV (Out Of Vocabulary) rate brings about many recognition problems. To partly alleviate this problem we collected manual transcripts of further 16 matches and designed a knowledge-base adaptation technique ensuring an efficient modification of a recognition lexicon and LM statistics. A suitable adaptation approach was also tested with a goal of adapting a LM to a style of speaking of a new commentator.
