Originální abstrakt

This paper describes several ways of acoustic keywords spotting (KWS),based on Gaussian mixture model (GMM) hidden Markov models (HMM) andphoneme posterior probabilities from FeatureNet. Context-independentand dependent phoneme models are used in the GMM/HMM system. Thesystems were trained and evaluated on informal continuous speech. Weused different complexities of KWS recognition network and differenttypes of phoneme models. We study the impact of these parameters on theaccuracy and computational complexity, and conclude that phonemeposteriors outperform conventional GMM/HMM system.
