PURPOSE:To enable high quality voice conversion by executing vectorization of plural rhyme in a frequency axis, obtaining a corresonding path by means of matching according to a dynamic planning method and utilizing this correspondence for frequency conversion. CONSTITUTION:Plural rhymes vectorization means 1 and 2 obtains a spectral envelope at maximum power for each of plural number of rhyme included in voice produced by each speaker. A corresponding path extracting means 3 obtains the corresponding path according to the dynamic planning method by matching the spectral envelope for the two rhyme corresponding to each other by means of the dynamic planning method. A frequency conversion means 4 executes the frequency conversion for each rhyme included in the sound of a speaker A by utilizing the corresponding path. Thus, since nonlinear conversion is executed for the spectral envelope for plural number of rhyme, the voice conversion in higher quality can be obtained. |
