A Study on Adapting Czech Automatic Speech Recognition System to Croatian Language
Original language description
After successful adaptation of our Czech large-vocabulary speech recognition system to Slovak, we investigate the possibility to port it to another Slavic language, Croatian in this case. We describe how we build a large lexicon (recently with 255 thousand entries) and a language model from publicly available Internet sources and how an existing Czech acoustic model (AM) can be utilized for bootstrapping and training a model applicable for Croatian. For the AM adaptation we use the Croatian part of theGlobalPhone database. An independent evaluation is done on a test set made of transcribed broadcast recordings of Radio Pula. When using the original Czech acoustic model, the word error rate is 27.6 %, with the model adapted to Croatian, it is reduced to 19.4 %.
