This paper describes the new framework of context-dependent (CD) Initial/Final (IF) acoustic modeling using the decision tree based state tying for continuous Chinese speech recognition. The Extended Initial/Final (XIF) set is chosen as the basic speech recognition unit (SRU) set according to the Chinese language characteristics, which outperforms the standard IF set. An adaptive mixture increasing strategy is applied when splitting the single Gaussian into mixed Gaussians in each tied state… CONTINUE READING
