Description
  • This paper describes preprocessor for the fully automated continuous speech transcription system. The preprocessing consists of the automatic segmentation followed by the broad-class segment identification.The former is capable of detecting speaker and/or acoustic changes in the BN audio stream with the precision being 82.75%. The latter acts as a filter that removes nonspeech parts.The performance of the proposed system was evaluated on the multi-lingual pan-European COST278 BN database containing data in 6 languages. The difference in performance between automatically and manually preprocessed BN streams was only minimal - 1.12%.

  • Tento článek popisuje systém předzpracování audio signálu pro účely automatické transkripce audio-záznamů. Předzpracování spočívá v automatické segmentaci signálu následované identifikací řeč/neřeč.Funkčnost systému byla ověřena na úloze automatického přepisu databáze televizního zpravodajství. Rozdíl v úspěšnosti přepisu mezi automaticky a ručně předzpracovanými daty byl pouze minimální – 1.12%. (cs)
