PROBLEM TO BE SOLVED: To provide a spatio-temporal resolution technique capable of minimizing an error and retaining ascending-order characteristics of LSP parameters.SOLUTION: A time function calculation unit 1 fixes a, and calculates a time function F and t, ..., tby dynamic programming. A difference LSP amplitude calculation unit 2 fixes the calculated time function F and t, ..., t, and calculates a difference LSP amplitude dby the dynamic programming. An LSP matrix calculation unit calculates a value of adefined by the following expression using the calculated difference LSP amplitude d. |
