PURPOSE:To provide teacher's voice appropriate for a learner by converting the rhythm information of an input voice into the rhythm information of a standard voice, synthesizing both the information and outputting the synthesized voice as the teacher's voice. CONSTITUTION:A pitch extracting/analyzing part 70 extracts the pitch of an input voice by using an input voice file analyzed by an input voice analyzing part 40 and receiving the sound element boundary of the input voice by a data collating part 50, finds out a pitch dividing position, analyzes the input voice file synchronously with the pitch, and writes the analyzed result in the 2nd synthesized wave forming file similarly to the pitch synchronizing analysis of the reference voice file. A synthesizing part 80 synthesizes a voice by using at least one of the rhythm information of reference voices and the residual characteristics and voice path characteristics of the input voice based upon the synthesized wave forming file to form a teacher's voice and the rhythm information of the teacher's voice is converted into that of the standard voice. A synthesized wave storing part 130 stoers the teacher's voice and outputs it when necessary. Thus, correct training can be attained. |
