Multi-Level Multi-Decision Models in ASR

Multi-Level Multi-Decision Models for Automatic Speech Recognition is discussed. It is hierarchically organized. Here there are not used the generative grammars for model speech signal synthesis as a feedback in speech recognition process. Instead of the latter significant decisions, but under simplified conditions, at all levels of a speech signal processing hierarchy are introduced. The 3-level model with phoneme recognizer, word recognizer and continuous speech interpreter is proposed. Experimental results for the 3-level model are given and problems to be solved are discussed.
