Description
  • Článek popisuje několik přístupů pro akustickou detekci klíčových slov pomocí GMM/HMM rozpoznávače a rozpoznávače zaleženého na dlouhých časových trajektoriích. V HMM rozpoznávači byly vyzkoušeny jak kontextově nezávislé tak kontextově závislé fonémy. Systém byl testován na záznamech meetingů, které jsou tvořeny plynulou neformální řečí. Byly vyzkoušeny různé konfigurace rozpozávací sítě a vlastnosti jednotlivých systémů jsou shrnuty v závěru. (cs)
  • This paper describes several ways of acoustic keywords spotting (KWS), based on Gaussian mixture model (GMM) hidden Markov models (HMM) and phoneme posterior probabilities from FeatureNet. Context-independent and dependent phoneme models are used in the GMM/HMM system. The systems were trained and evaluated on informal continuous speech. We used different complexities of KWS recognition network and different types of phoneme models. We study the impact of these parameters on the accuracy and computationnal complexity, and conclude that phoneme posteriors outperform conventional GMM/HMM system.
