Abstract: PURPOSE: A codebook based high-speed operation method for improving sounds is provided to reduce operation quantity while maintaining the performance by using a code-vector selection mode. CONSTITUTION: A codebook based high-speed operation method for improving sounds is as follows. A noise code vector is selected from noise codebooks (S100). Sound code vectors and the selected noise code vectors are combined so that an optimal sound and noise vector index is searched (S200). [Reference numerals] (AA) Start; (BB) Finish; (S100) Select one noise code vector by using an equation 15; (S200) Search optimal sound and noise code vectors by combining sound code vectors and the selected noise code vector
