SYSTEM AND METHOD FOR SPEAKER ADAPTATION USING BILINEAR MODEL

摘要

PURPOSE: A system and a method for adapting a speaker which used bi-linear model are provided to improve performance of speaker adaptation by controlling the number of estimation parameter according to the number of adaption data. CONSTITUTION: An observation matrix configuring unit(22) comprises observation matrix by using SD model which is comprised by considering mean vector. A bi-linear model configuring unit(23) calculates asymmetric bilinear model parameter by applying SVD about the comprised matrix. The bi-linear model configuring unit comprises a bi-linear model by performing linear transformation as a space which reflects the style of a speaker. If an adaptation data of a new speaker comes in, a speaker suitability part approximates only the style factor to constitute a speaker adaptation model.
