A speech synthesizing method of statistical speech synthesis system using a switching linear dynamic system

PURPOSE: A method for combining sounds of a statistical speech combining system using a switching linear dynamic system is provided to apply a voice database and a switching linear dynamic system which learns an existing education system, thereby combining voices. CONSTITUTION: A system learns a statistical model from a voice database. The system learns a system parameter of a switching linear dynamic system using an ML(Maximum Likelihood) method(S100). The system selects a statistical model and a converter corresponding to an input sentence or an input word. The system uses a learnt statistical model value as an input value. The system combines voices which are from a combined feature vector of the switching linear dynamic system(S200).
