    Silence/speech detection method based on set of decision graphs

  • Original language description

    In the paper we demonstrate a complex supervised learning method based on a binary decision graphs. This method is employed in construction of a silence/speech detector. Performance of the resulting silence/speech detector is compared with performance ofcommon silence/speech detectors used in telecommunications and with a detector based on HMM and a bigram silence/speech language model. Each non-leaf node of a decision graph has assigned a question and a sub-classifier answering this question. We testthree kinds of these sub-classifiers: linear classifier, classifier based on separating quadratic hyper-plane (SQHP), and Support Vector Machines (SVM) based classifier. Moreover, besides usage of a single decision graph we investigate application of a set of binary decision graphs.

    Metoda detekce řeči a ticha založená na množině rozhodovacích grafů

  • Czech description

    V práci demonstrujeme komplexní metodu strojového učení založenou na množině binárních rozhodovacích grafů. Tato metoda je využita při konstrukci detektoru řeči a ticha. Přesnost výsledného detektoru je porovnána s přesností bežných metod pro detekci ticha a řeči používaných v prostředí telekomunikací a s detektorem založeným na HMM s bigramových pseudo-jazykovým modelem.
