Fuzzy parameter clustering method in speech recognition


The paper proposes a parameter clustering method using fuzzy clustering analysis to decrease the parameter size efficiently and improve the robustness of parameter training in large vocabulary continuous speech recognition systems. Based on the structure of a phonetic decision tree, leaf nodes are used for Gaussian fuzzy clustering and the root node or… (More)
